Biogas block-type thermal power station with pilot injection engine

SEVA Energie AG block-type thermal power stations –

modern and environmentally compatible technology for electricity and heat generation

The SEVA Energie AG is active in the future-oriented market of regenerative and alternative energies.

on the production of block-type ther-

mal power stations. Since 2001 the

SEVA Energie AG has been producing

its block-type thermal power stations

at its new location, the Ecopark in

Emstek.

SEVA INTRODUCES ITSELF

Tradition and know-how

The SEVA Energie AG was established in

1982 as a GmbH (limited liability com-

pany). SEVA staff recognised quite early

that a change would come about in the

realm of electricity and heat gen-

eration. The anticipated scarcity of fos-

sil fuels, restrictions in the utilisation of

nuclear energies and the intensifi ed uti-

lisation of wind power stations clearly

showed the enormous potential in the

utilisation of regenerative energies.

With the objective of generating elec-

tricity and heat effi ciently, SEVA

started in the early 1990’s with the

construction of block-type thermal

power stations (also known as com-

bined heat & power plants, CHP), ini-

tially for operation with heating oil or

natural gas, and later increasingly for

application in biogas plants. The

increasing demand for block-type ther-

mal power stations led to the construc-

tion of a production and offi ce building

in Ahlhorn in 1993. The SEVA Energie

AG was established by Günther J.

Schulz on 1 January 2000; from then

on the fi rm placed its main emphasis

The SEVA Energie AG is a continually

growing, innovative company, which is

amongst the leading manufacturers of

biogas block-type thermal power

stations in Germany.

SEVA, your competent partner in energy matters

Today the SEVA Energie AG employs

150 people, and is an apprentice-

training enterprise for commercial

professions, mechatronics specialists,

electricians as well as for information

science specialists and logistics special-

ists. In 2007, the company produced

block-type thermal power stations with

an installed total output of 60 mega-

watts on a present-day production

area of �,000 m2.

In addition to several distribution

and service branch establishments

in Germany, the SEVA Energie AG is

also active on the international market.

For instance, SEVA contact partners

are available for customers in the USA,

Luxembourg, Italy and Japan. There is

also an increasing interest in block-type

thermal power stations abroad, and

particularly in the SEVA Energie AG’s

know-how with regard to the utilisation

of regenerative and alternative energy

sources.

In addition to the EU countries, Eastern

Europe and above all the USA are inter-

Fully developed technology and efficient concepts

BLOCK-TYPE THERMAL POWER

STATIONS

Function and technology

As a result of the generation of electric-

ity and heated coupled in block-type

thermal power stations, the utilised pri-

mary energy utilised is optimally exploi-

ted. The burden on the environment

is thereby relieved vis-à-vis the con-

ventional supply of electricity and heat

from power stations and boilers.

SEVA Energie AG block-type thermal

power stations achieve electricity-side

efficiencies of over 40 %. In compari-

son with uncoupled generation of elec-

tricity and heat, the utilisation of these

block-type thermal power stations

allow considerable energy savings

(over 35 %) to be realised.

The SEVA Energie AG aggregates are

for the most part produced for utili-

sation in biogas plants and operation

with vegetable oil. If one compares the

CO2 emissions of a block-type ther-

mal power station with the emissions

from normal power stations and boil-

ers, the block-type thermal power

station shows a much more favourable

CO2 balance and protects the environ-

ment. Refraining from the utilisation

of fossil fuels allows a virtually CO2–

neutral utilisation of block-type

thermal power stations.

In addition to the application in bio-

gas plants, this decentralised form of

energy supply is also industrially applied

for provision of process heat or for

steam generation. In addition to

block-type thermal power stations for

operation with regenerative and fossil

fuels, SEVA Energie also plans and

builds turnkey facilities, such as com-

plete biogas and vegetable oil

plants. Furthermore, SEVA offers heat

supply contracts (also called contract-

ing), and provides favourable heat at

predetermined prices.

As an operator and reliable partner, the

SEVA Energie AG then takes care of the

planning, financing and regular mainte-

nance of the heating plant.

As a result of the coupling of the waste

heat from cooling water, charge air and

waste gas, the facilities (with supply

temperatures of 90 to 110 °C) are ide-

ally suitable for utilisation in proximity

heating networks and building

heating systems.

Comprehensive and permanent control

CONTROL ENGINEERING

Reliability and competence

The service life of SEVA block-type

thermal power stations (over 8,000

hours) and the 24/7 availability necessi-

tates – in addition to regular mainte-

nance – reliable and robustly desig-

ned mechanical and electro-technical

components.

In its automation concept the SEVA

Energie AG relies on switching devices

and automation components from

renowned German manufacturers.

These system components monitor and

display. This infrared touch panel has a

robust operating interface made of

composite safety glass and also ensures

constantly reliable operation under

rough environmental conditions.

A remote diagnosis or remote access

to the system via a PC can take place

by means of a router included in the

scope of delivery and an ISDN connec-

tion available to the customer.

cooling and hot water temperature

as well as the oil level and fuel supply.

These data are compiled in a decentra-

lised manner via a remote system,

and routed to the central control

mechanism by means of an interface.

The visualised control automation

(VISTA) supports the operation and dis-

play of operating data via a 5.7” touch

Block-type thermal power stations

operated with vegetable oils are uti-

lised in agricultural livestock breeding

enterprises.

Among the preferred fields of applica-

tion in the municipal realm are combi-

nations of significant heat consumers

such as indoor swimming pools and

school centres with the surrounding

residential building. But other large

individual objects such as hotels, old

peoples’ homes, hospitals, housing

areas well as multiple family dwellings

are predestined for the utilisation of

block-type thermal power stations.

That‘s how the operation of block-type

thermal power stations from the SEVA

Energie AG makes it possible for the

operator to become independent from

a central energy supply with the cer-

tainty of modern and above all environ-

mentally compatible, innovative tech-

nology for provision of electricity and

heat.

Moreover, the company attaches spe-

cial importance to a high degree of

production depth as well as fast and

reliable service.

GAS OTTO ENGINES

Performance and effi ciency

Gas Otto engines work according to

the internal combustion principle, and

have been specially developed for ope-

ration with gas. The operation with

high-grade combustible gasses such as

methane (CH4), the main constituent

of natural gas, is characterised through

a high degree of effi ciency, a clean

combustion and a good CO2 balance.

In order to minimise the nitrogen oxide

emissions, the engines are operated as

so-called “lean-burn engines” with a

high degree of excess air.

Gas Otto engines are applied, amongst

other things, for energetic utilisation

of lean gases which are created during

the fermentation of organic wastes

(biogases and landfi ll gases). Gas Otto

engines can also be operated with

other types of gases such as natural

gas or propane gas, which can be use-

ful for starting biogas plants in order

to provide the necessary process heat.

The SEVA Energie AG produces block-type

thermal power stations for small and medium-

size gas engines in the power range from

50 kW to 1,700 kW. The well-develop ed

technology enables safe operation of these

engines with biogas under compliance with

waste gas limits according to TA air.

VEGETABLE OIL ENGINES

Stability and attractiveness

Vegetable oil-driven block-type thermal

power stations are considered to be an

effi cient alternative to aggregates

which are operated with fossil fuels.

The engines utilised in these block-type

thermal power stations are serial diesel

engines which are adapted by the

SEVA Energie AG for operation with

vegetable oil.

After reaching the operating tempera-

ture, a changeover to vegetable oil

operation takes place automatically,

and the aggregate is supplied with

fuel from the main tank. In turn, an

automatic changeover to operation

with biodiesel occurs if the block-type

thermal power station is turned off,

and the lines for the fuel supply as well

as the engine are fl ushed.

SEVA Energie AG vegetable oil block-

type thermal power stations are

resistant to long-term utilisation of

vegetable oils.

Because of the exclusive utilisation

of technically well-developed

engines and components of the

highest workmanship quality, the

SEVA Energie AG aggregates are opti-

mally equipped for stronger material

stress through the utilisation of vege-

table oil.

SEVA produces vegetable oil block-type

thermal power stations with thermal

outputs ranging from 100 to 550 kW,

and thus offers its customers a large

selection of block-type thermal power

stations featuring various power

classes.

PILOT INJECTION ENGINES


Pilot injection engines work accord-

ing to the diesel principle and are self-

ignition engines. Industrial diesel

engines, which are adapted to gas

operation through modifi cations, are

frequently utilised.

With pilot injection engines only the

energy required for igniting the fuel

mixture is drawn from the injection

system. Similar to an Otto engine,

A pilot injection block-type thermal power station for installation in an engine room

the main portion of the energy is pro-

vided via the suction system.

These pilot injection engines are utilised

in biogas block-type thermal power sta-

tions in order to burn biogas. For this

purpose the biogas is admixed to the

combustion air by means of a gas

mixer and ignited through the sup-

plied ignition oil. In contrast to

natural gas, biogas has a very high

antiknock quality, and can therefore be

drawn into these diesel engines with-

out the danger of a spontaneous igni-

tion. Adjustments are made so that the

ignition oil portion maximally amounts

to 10 % of the supplied fuel output.

Maximum safety for continuous operation

Included amongst these emergency

power generators is a modern plant

control system, which automatically

starts the back-up power supply in

case of emergency, and later – if the

public network can reassume the sup-

ply – switches back to the network.

Furthermore, the SEVA Energie AG

also offers peak-load generators

for short-term energy demand. These

peak-load generators ensure the supply

in the event of fl uctuating supply, and

enable production operations to

achieve stable and particularly safe

energy management.

These systems are controllable, and the

foreseeable peak load can also cover

load peaks within the range of minutes.

Peak load is frequently traded on elec-

tricity exchanges, where in the extreme

case it can cost several euros per kilo-

watt hour, and the provision of any

Safety and protection

Electricity is a resource of elemen-

tary importance for all companies.

Various environmental incidents show

that the public electricity supply is not

always able to cope with extreme infl u-

ences such as storms, snow, ice and

fl oods. And so it is meaningful for

companies to make themselves inde-

pendent vis-à-vis external disturbances

by obtaining their own electricity

supply systems.

With an emergency power generator

from the SEVA Energie AG, ongoing

operation can be maintained in such

emergency situations by means of a

stable emergency power plant.

As a result of this reliable safety facil-

ity, the customer is protected against

economic losses, and is naturally also

able to provide important devices, sys-

tems and production processes with

electricity over a longer period of time.

supply fi rm is very expensive.

The costs can be considerable reduced

through a high-quality peak-load gen-

erator from the SEVA Energie AG.

SPECIAL ACCESSORIES

Flexibility and variety

SEVA Energie AG containers are spe-

cially manufactured for the installation

of block-type thermal power plants.

Depending on the model of installed

block-type thermal power station, the

containers are delivered in various sizes

ranging from 20 to 40 feet long. With

their special width and special height

of 3 metres, these containers are larger

than the otherwise delivered standard

container, and are also offered as a two-

room or three-room container.

For biogas processing the SEVA Energie

AG offers gas cooling mechanisms

for all deliverable block-type thermal

power stations. In this connection the

biogas is dehumidifi ed or dried through

compressor cooling and a shell-and-

tube heat exchanger. As a result of

this drying process, the water is con-

densed, collected and drained off.

On request, SEVA Energie AG gas fl ares

are immediately mounted with the block-

type thermal power station, or also

mounted afterwards. The gas fl ares are

included in the various services, and are

supplied and mounted including control

cabinet.

Tank farms are also included in the

scope of delivery from the SEVA Energie

AG. And so in addition to double-walled

tank systems ranging from 1,000 to

100,000 litres, customers can also pro-

cure special tanks for underground

storage and insulated tanks for the stor-

age of vegetable oils. Moreover, the

SEVA Energie AG offers a tank control

mechanism for vegetable oil plants,

which has been specially developed for

utilisation with vegetable oil in two-tank

systems. The tank farms are delivered

as ready-made mounted, and include

the piping for the block-type thermal

power station.

SEVA Energie AG heating distributors

are mainly installed in containers, but can

also be utilised for installations in

engine rooms. On request, the distribu-

tors will be equipped with pumps, mix-

ers and heat meters.

Customers are offered various solution

possibilities for sound reduction.

The motor sound can be reduced by up

to 40 dB(A) at a distance of 10 metres

through specially manufactured sound-

absorbing hoods. The waste gas

sound can be reduced through the utili-

sation of combination sound

absorbers so that plant operation is

even possible in residential areas. The

re-cooling systems can also be delivered

as sound-reduced. The SEVA Energie

AG works together with experienced

sound experts in order to take into

account any problems with sound insu-

lation, even in the planning phase.
