REPORT SUMMARY

In order to meet the requirements of the South African Air Quality Act No. 39 of 2004

(Reference 9.1), all Solid Fuel Combustion Installations (Category 1.1) such as Kendal Power

Station, are obligated to monitor several listed pollutants during operation. These pollutants

include particulate matter, Sulphur Dioxide and Oxides of Nitrogen. The Act further specifies

that all particulate monitoring programs are required to meet international standards such as

ISO 9096 & 12141 (Reference 9.2 & 9.3) and therewith ISO 10155 (Reference 9.4). To this

end and in keeping with the ESKOM Standard for Emission Monitoring and Reporting (420-

56242363) (Reference 9.5) Eskom’s Kendal Power Station scheduled particulate emission

monitor correlations on Units No. 2 & 6. The risks areas included Units No. 2 & 6’s

electrostatic precipitators and the pollutant considered was particulate matter (particulate

emission monitors correlations).

Continuous particulate emission monitors generally operate on a principle of passing a light

beam through a dust-laden gas stream. The dust concentration is then determined by measuring

the degree of light attenuation resulting from the dust within the gas stream. However the

degree of light attenuation is dependent on more than just the quantity of dust. Dust

characteristics such as colour, size, shape and distribution of the dust within a duct, will all

impact on the amount of light that is attenuated. In addition, these characteristics will change

over time as the plant’s electrostatic precipitator or bag filters performances change. In order to

compensate for these characteristic changes and to facilitate the determination of mass

emissions from the light attenuation, a correlation of light attenuation and measured mass

emissions must be conducted at regular intervals. The correlation of the light attenuation and

mass emission requires the determination of the actual mass emission emitted from a particular

plant by means of isokinetic or Gravimetric dust sampling. This procedure must be conducted

over a range of plant operating conditions representative of the plant’s general operating

conditions and is referred to as a particulate emission monitor correlation or a dynamic

calibration.

Stacklabs, an environmental testing laboratory, was contracted by Eskom Kendal Power Station

to complete the required particulate emission monitor correlations on Units No. 2 & 6. The

required site measurements were carried out from the 30th of August to the 10

th of September

2016. The relevant results and correlation graphs have been presented in this report and may be

summarised as follows:

Report Recommendations

It is recommended that:

The particulate emissions from Units No. 2 & 6 reported to the authorities are according to

the correlation function presented in Figures No. 1 & 2 of this report.

New compliant correlations are conducted on Unit No. 2 & 6 during the third quarter of

2018.

# Kendal Power Station Units No 2 & 6 Correlation August & September 2016 Report No. RSL224 Page 1 of 62

1. Monitoring Objective

The primary objective of the particulate emission monitor correlations presented in this report

is to quantify the concentrations of the particulate matter released into the atmosphere during

the operations of Units No. 2 & 6 at Kendal Power Station.

The requirement for conducting the particulate emission monitor correlations is to demonstrate

compliance with the requirements of the National Environmental Management: Air Quality Act

(39/2004), Listed Activities and Associated Minimum Emission Standards in terms of Section

21, Category 1.1. The substance applicable under Category 1.1 is Particulate Matter which is

capped at 100 mg/Nm3 dry @ 10% O2. This cap limit however, in the case of Kendal Power

Station, was negotiated to 200 mg/Nm3 dry @ 10% O2.

2. Plant Description & General Operating Procedure

2.1. The pulverised fuel steam generating boilers on which the particulate emission monitor

correlations were conducted were originally designed for a maximum steam flow equivalent to

697MW. These boilers were each equipped with two parallel electrostatic precipitators with a

design capacity of 1070 Am3/s gas flow and a performance collecting efficiency of greater than

99.93%. The electrostatic precipitators were later retro-fitted with sulphur trioxide flue gas

conditioning.

2.2. During the correlations, the particulate emission measurements were conducted through

purpose built ports situated on the various Units’ stacks at a level approximately 180m above

ground level. For a diagrammatic representation of the test positions, see the following sketch.

Measurements were conducted along sections Q—Q.


2.3. The operating regime followed during the correlation periods included all significant activities

that arise during normal production as well as some fault conditions. The correlation included

measurements at the following Boiler Loads:

*Measurement No. 8 on Unit No. 6 was not completed due to an unexpected unit shutdown.

A total of 9 measurements were completed on Unit No. 2.

For additional information of the plant parameters please see Appendix No. 2.

3. Methods & Procedures

The method selected for the determination of the particulate emission concentrations on Units

No. 2 & 6 was in compliance with ISO 9096 Stationary source emission – Manual

Determination of mass concentration of particulate matter.

This general method can be briefly described as follows:

A sharp-edged nozzle is positioned in the duct facing into the moving gas stream and a sample

flow of the gas is extracted isokinetically for a measured period of time. To allow for non-

uniformity of the distribution of particulate concentration in the duct, samples are taken at a

pre-selected number of stated positions in the duct cross-section. The particulate matter

entrapped in the gas sample is separated by a filter medium, then dried and weighed. The

particulate concentration is calculated from the weighed particulate mass and the gas sample

volume. The particulate mass flow rate is calculated from the particulate concentration and

the duct gas volumetric flow rate. The particulate mass flow rate can also be calculated from

the weighed particulate matter, the sample time, the area of the sample plane and the nozzle

opening.

The degree to which this sample represents the total gas flow depends on

Homogeneity of the gas velocity within the sampling plane;

A sufficient number of sampling points in the sampling plane;

Isokinetic withdrawal of the plane

As stated above, the gas has to be sampled at more than one sampling point in the sampling

plane, dependant on the sampling plane area. This plane is normally divided into equal areas,

at the centres of which gas is withdrawn. To determine the particle concentration in the plane,

the nozzle is moved from one sampling point to the other, extracting gas isokinetically at each

point. Sampling periods should be equal for each sampling point, resulting in a composite


sample. If equal sampling areas cannot be chosen, the sampling period shall be proportional

to the sampling area. The sample is extracted through a sampling train, which principally

consists of:

A sampling probe tube with entry nozzle;

A particle separator;

A gas metering system, in-stack or external;

A suction system

The particle separator and / or the gas metering system may be located either in the duct, or

placed outside the duct.

It is necessary to avoid condensation of vapour in the sampling train during gas sampling,

because it will interfere with particle separation, particulate condition and flow measurements.

To this end, the probe tube, the particle separator and the gas flow-measuring device may be

heated above the relevant dew point where necessary. The water vapour may intentionally be

removed downstream of the particle separator, to make use of a dry gas meter for the

measurement of sampled gas volume.

For isokinetic sampling, the gas velocity at the sampling point in the duct has to be measured,

and the corresponding sample gas flow has to be calculated and adjusted.

Normally a Pitot static tube is used for the measurement of duct gas velocity. If the sample gas

flow-measuring device is used within the duct, the relationship between the measured pressure

drop and the pitot static tube differential pressure is simple, facilitating the adjustment to

isokinetic conditions. If the gas meter device is situated outside the duct, the calculation of the

isokinetic sample gas flow rate is more complicated. The calculation may also include the duct

gas density under standard conditions (which may be derived from the dry gas composition and

the moisture content), the temperature, static pressure of the gas in the duct, the gas meter

device, and the water vapour content of the duct gas, if the sample gas flow is measured after

water removal.

After sampling, the collected particulate matter is completely recovered, dried and weighed and

the concentrations are determined.

All Stacklabs isokinetic sampling is carried out employing procedures and equipment that

comply with the requirements of ISO 9096 12141 1992 (Reference 1). All Stacklabs sampling

equipment is calibrated by SANAS accredited laboratories.

Kendal personnel were responsible for the setting of the plant prior to the test period. Stacklabs

was contracted to provide the service of particulate emission monitors correlation through

isokinetic dust sampling only.

The broad outlines of filter weighing, pre-test preparations, sampling system integrity checks

and sampling procedures are discussed in Appendix No 5.

5. Discussion

5.1. Unit No. 2 Total Particulate Matter (TPM) Monitor Correlation

The correlation on Unit No. 2 was completed from the 2nd

to the 10th of September 2016. A

total of 9 measurements were conducted. The measured particulate emission concentrations

ranged from 15.4 to 42.3 mg/Nm3 Dry @ 10% O2, well below the negotiated cap value of 200

mg/Nm3 Dry @ 10% O2. The corresponding particulate emission monitor signals, recorded

from Output No. 1, ranged from 5.2 to 6.3 mA over an operating range of 537 to 676 MW. The

resulting co-ordinates produced the following correlation with a coefficient of 0.98, well within

the standard’s tolerance of 0.95 to 1.00.

The figure above also includes, for comparative purposes, the Measurement co-ordinates from

the previous correlation conducted in December 2015. It can be seen that the co-ordinates from

the 2015 correlation support the new correlation, with all 9 of the 2015 co-ordinates falling

within the 2016 September correlation tolerance intervals. It can however also be seen that the

particulate emissions measured from Unit No. 2 have significantly decreased from December

2015 to September 2016. The average emission concentrations measured in December 2015

was recorded as 118 mg/Nm3 dry @ 10% O2 whereas the average emission concentration

measured in September 2016 is 29.5 mg/Nm3 dry @ 10% O2.


5.2. Unit No. 2 Airflow to Gas Flow Correlation

The Total Air Flow to Gas Volume Flow Rates correlation was also determined during this

period. The measured gas volume flow rates, which ranged from 702.7 to 905.4 Nm3/s Dry

@ 10% O2, were correlated against the plants corresponding Total Air flow Rates to produce a

correlation with a coefficient of 0.99. No measurements were excluded from the final Total Air

Flow to Gas Flow correlation.

The following trends indicate typical normal load and air flow variation experienced during the

Measurements on Unit No. 2.

5.4. Unit No. 6 Total Particulate Matter (TPM) Monitor Correlation

The correlation on Unit No 6 was completed from the 30th of August to the 8

th of September

2016. A total of 11 measurements were conducted on Unit No. 6 however measurement No. 8

was not completed due to a unit shut down that coincided with this measurement. The measured

particulate emission concentrations ranged from 27.2 to 114.9 mg/Nm3 Dry @ 10% O2, well

within the cap value of 200 mg/Nm3 Dry @ 10% O2. The corresponding particulate emission

monitor signals, recorded from Output No. 1, indicated values from 5.5 to 11.0 mAs over an

operating range of 392 to 677 MW. The resulting correlation complies with the requirements

of the ISO 10155 and the Eskom standard for Emission Monitoring & Reporting and may be

used in the report of emission form Unit No. 6.

5.5. Unit No. 6 Airflow to Gas Flow Correlation

The Total Air Flow to Gas Volume Flow Rates correlation was also determined during this

period. The measured gas volume flow rates, which ranged from 479.4 to 945.6 Nm3/s Dry @

10% O2, were correlated against the plants corresponding Total Air flow Rates to produce a

correlation with a coefficient of 0.99. No measurements were excluded from the final Total Air

Flow to Gas Flow correlation. The following Boiler Load trends indicate the normal load

variation experienced during the Measurements on Unit No. 6.


6. Monitoring Deviations

6.1. A total of 9 & 10 measurements were included in the correlations of Units No. 2 & 6

respectively. The Eskom Emission standard set a target of 12 measurements for correlations on

ESP Unit, however this could not be complied with during the allocated time period due to an

unscheduled unit shut down and plant constraints.

7. Recommendations

It is recommended that:

7.1. The particulate emissions from Units No. 2 & 6, reported to the authorities, are according to the

correlation functions presented in Figures No. 1 to 4 of this report.

Filter Weighing Procedure

Sampling System Integrity Checks

And

Sampling Procedures


1. FILTER WEIGHING

Before the test, the filters are prepared as follows:

The required numbers of filters are marked with a unique number. The filters are then heated

in an oven at 120 degrees Celsius for a period of one hour. After heating, all the filters are set

out together with three reference filters in a dedicator where they will condition for a period of

48 hours. Each filter is then weighed three times, in a temperature controlled clean room,

where the masses are captured on a dedicated computer system. Following the weighing

process, the filters are packed and sealed into a separate container ready for use. The reference

filters are treated in the same manner as those earmarked for the tests, but are not taken to site.

After the site measurements, the used and reference filters are again set out in the desiccators

and allowed to condition for up to 100 hours. The same weighing procedure is again followed

and the final contaminant masses are calculated by the computer system.

2. PRE-TEST PREPARATIONS

On site, the equipment is set up at the measuring location. The inside dimensions of the duct

are determined. The number of test points per traverse is determined according to the standards

and the sampling probe marked accordingly

3. SAMPLING SYSTEM INTEGRITY

A leak check is performed on the impulse lines to ensure measurement integrity.

With each change in filter or any other operation which might influence the integrity of the

vacuum system, a vacuum check is performed. This ensures that only the gas which entered the

nozzle will be measured by the gas test meter. Gaseous analysers are zero and span checked

with calibration gas at the measurement points.

4. SAMPLING PROCEDURE

Gas temperature, pressure and velocity head readings are logged at each sampling point.

Velocity head readings are updated at intervals of 1 minute. During this time, the computer

program calculates the orifice flow settings required for isokineticity and the flow is adjusted

accordingly with each update, either automatically or manually depending on the particular

system used.

Oxygen in the flue gas is measured to determine gas density.

An orifice flow meter is used to facilitate the adjustment of the sampling flow rate at one-

minute intervals. The relevant parameters for flow calculation are entered into the computer.

The computer is programmed to determine the flow rate through the orifice in order to achieve

isokineticity. A dry gas meter is incorporated into the sampling train and is used to record the

total actual volume sampled and therewith to determine the percentage isokineticity.

Moisture is separated from the sampled gases during sampling, using a water trap and silica gel.

The ‘A’ indicator in the silica gel changes colour as moisture is absorbed. The accumulated

liquid is used after the test to determine the moisture content on a percentage-by-volume basis.

This value is again incorporated into the volume of dry gas sampled to determine the

concentration of pollutants in the gases at Actual and Normal (sometimes referred to as

Standard) conditions.

The uncertainty before the test, about the moisture content in the gas, fluctuation in the gas

flows and human error contribute towards the final deviation from 100 % isokineticity.


After completion of a measurement the relevant sampling components may be rinsed in order to

capture pollutants that may have become attached to the sampling system’s exposed surfaces.

The rinse medium is captured and contaminants within will be added to the total sampled mass.

Relevant plant operating parameters are logged, where possible, for reference purposes and it is

usually recommended to take raw product samples during the tests. The content of certain

elements in the raw product has specific bearing on plant performance and is useful for

comparative reference.

On completion of all the site measurements the equipment will be removed from the plant,

returned to the laboratory and work shop for processing and cleaning. Where necessary,

additional calibration checks will be conducted on specific instruments to determine operational

continuity.
