Diesel power station

In diesel power stations diesel is used as the fuel and electricity generated by rotating prime mover by diesel engines. Fuel price is high, so these plants are used to supply low power demands and used as stand by power stations.

Arrangement of diesel power station

Fuel supply system

This system consist of following components. Fuel tank to store the fuel, then some amount of fuel store in the day tank for daily of shortage uses. Filters are used to remove the impurities and fuel transfer pumps are used to pump the fuel.   

Air intake system

Get fresh air from the atmosphere and send them to the diesel engine. It is used filters to remove particles from the air.

Exhaust system

Remove exhaust gas to the atmosphere. It is used silencer to reduce the noise level.

Cooling system

This system is consist of water pumps and cooling towers. Pumps circulate water through cylinders and head jackets then take excess heat from the engine and releases them in the cooling towers. Why cooling is needed? Because all the heat energy created within the engines are not completely converted into the work. Some part remain, if that remain part is not remove it may cause to make damages to the equipment’s.

Lubrication system

This system consist of lubrication oil tank, pumps, filters and also oil coolers to keep oil temperature in low value.

Engine starting system

Basically it is used compressed air for starting. In this case an air compressor is used to make compressed air. That compressed air is fed to some cylinders. Then they act as reciprocating air motors. Fuel is injected to the other cylinders. So after starting engine makes its own power.
