Introduction to MAN 18V28/32S

The MAN 18V28/32S Generator Set is a well-proven m edium-speed unit providing over 4 M W at

ISO conditions. It is conservatively rated and offers exceptional reliability and operating economics.

(see the attached)

The prime mover for the Generating Sets is a MAN 28 cm bore Medium-Speed Diesel Engine with

18 cylinders in VEE configuration. The Engine is turbochar ged and intercooled and is

conservatively rated; both in terms of its piston speed and its operational pressures and temperatures.

The Engine runs at 750 rev/min, and is suitable for continuous base load operation on HFO (Heavy

Fuel Oil) with viscosity up to 700 centistokes (cSt) at 50 deg C and with a sulfur content up to 3.5%.

Engine Jacket and Fuel Oil Hea ting Systems enable the Engines to operate without delay on HFO,

reducing the consumption of expensive Light Diesel Fuel to an absolute minimum.

Integral Fuel Injector C ooling Systems are provi ded, preventing the build up of fuel deposits and

cold corrosion on the injector nozzle tips.

This solution is constructed so that groups of three (3) G enerator Sets share fueling and other

auxiliary systems to reduce both set up costs and installation time.

These M3 Plants can be linked together to create Power Plants from 12 to 72 MW.

Acoustic EnclosuresEach Gener ating Set is insta lled w ithin a pu rpose designe d and built enclosur e th at achieves a

reduction in Plant noise levels by up to 50 db(A).

The Enclosures are of su fficient size to enable al l Plant servicing and major overhauls to be carried

out within the protected environment of the Enclosure.

The Enclosure is designed to be transportable within ISO 40 ft c ontainers and then easily

constructed at the generation site piece by piece.

Electrical Module

The primary function of this Module is to s ynchronize the outputs from the individual Generating

Sets. To provide the Plant output to a Power Transformer or to Switchgear.

To provide auxiliary supplies throughout the Plant and to provide a Black-Start capability.

HFO Fuel Tank

Based upon a standard ISO 40-foot c ontainer, this Module provides suf ficient fuel to operate each

group of three MAN Generating Sets at maximum continuous output for approximately 24 hours.

A number of Tanks could be grouped together and stacked to increase fuel storage capacity.

Constructed with an integral bund wall to contain spills, and with integral h eating coils, an HFO

Buffer Tank is located adjacent to each group of Generating Sets.

A Local Pumping Chamber with duty/standby units transfers the f uel oil dir ectly to th e HFO

Treatment Module.

5/13

Water Pumping System

The Engines have clos ed-circuit air-blast Radiat ors and water consum ption is f or initial f ill and

occasional make-up only.

The HFO and Lube Oil centrifuges use a sm all amount of water to maintain a gravity seal in the

centrifuge bowls, but this water can be treated and re-used if required.

Fire Pumps complying with current NFPA standards, and a Reverse Osmosis unit providing process

and drinking quality water for the plant and domestic facilities are Contained in Module 7.

Multi-function Skids

The multi-function skid installed be tween the E ngine and the end wall of the a coustic Enclosu re

contains the Engine starting air supplies, Air Compressors, Fuel Changeover System , Injector

Cooling Module, Dosing System for Engine coo ling water , Lube Oil Centrifuges, and the

Emergency Fuel Shut-Off System.

Modular Radiators

The Engine Cooling Radiators are a closed circuit, fan cooled design, with zero evaporation losses.

They are suitable for continuous operation in high ambient and high humidity conditions.

Fan operation is controlled therm ostatically to optimize operational efficiency, and pipe work and

control cabling are already fitted into the Modules.

The vulnerable soft alloys necessary for ef ficient cooling are encased in a robust space-fram e for

transport.

The frame then becomes the Radiator support stand when the unit is mounted adjacent to the Engine

Enclosure

Radiators

Standard Pipe work and Connections

The pipe Modules link the different items of Plant to enable them to run as a fully-integrated Power

Station.

The size of the individual Modules and thei r connection system s ha ve been designed and

manufactured to minimize site work and to achieve the fastest possible installation times.

These Modules carry the Fuel Oil, both Light and Heavy, from the bulk s torage facility to the Fuel

Treatment and forwarding Plant and on to the Engines.

They also carry the Engine Cooling Water to the Radiators and the site support services:-Fire Main,

Domestic (Potable) Water and Compressed Air.

Air Filters

Oil-bath Air Filte rs pre vent abra sive dusts and particles f rom entering the sensitive com bustion

spaces within the Engines.

Easy to clean and m aintain, these Air Filters enab le the Generating Sets to be used in dif ficult

environmental conditions.

Exhaust System

Exhaust gas from the Engines is routed through an economizer to achieve high operating efficiency.

The Silencer achieves approximately 45 bB(A) reduction in noise levels and the height of the S tack

can be adjusted to meet gas dispersion requirements.

Control Centre

Based upon an ISO 40-foot Contain er, this Module provides the air-conditioned heart of the Power

Plant.

All generating operations are controlled from t his point, including ener gy dispatch to the power

purchaser, data logging and trend analysis of all key operating functions, communications with local

and national control centers, and starting and stopping of the individual Generating Sets.

Dimensions:The plant consists of two 12 MW blocks (3 x 4 MW). They can be used together and independently.Each 12MW self-contained block (3 units) requires a site with dimensions 55m x 35m.The layout/position of each component is fixed within the design and cannot be altered beingcontainerized.

The position of the two 12MW blocks with respect to each other is flexible.

Within the generic layout drawing the 24MW power plant occupies a site with approx. 18,000 meterssquare (dimensions: 140m x 130m).This includes a bulk HFO storage tank and HT electrical switch yard (in your case 33KV) as well as agenerous access/perimeter road and perimeter fence buffer.
