Gas Engine

Gas engines are similar to traditional combustion engines with the main difference being the way the fuel and air are mixed. A petrol engine uses a carburettor or fuel injection whereas a gas engine uses a three-valve system with separate inlet valves for air and gas.

Engine sizes vary with power outputs ranging from 185 kW to 640 kW. The electrical efficiency of a gas engine is typically about 40%, with a heat efficiency of about 40% (at less than 100°c).

How it Works

A Gas Engine is similar to the engine in your car except that instead of using petrol or diesel as a fuel source, biogas is used. A Gas Engine converts the energy within the biogas via our process similar to a convential combustion engine. The drive shaft is used to generate electricity by turning an electric motor, whilst the heat is captured from the exhaust and the water jacket of the engine to make hot water or low pressure steam.

Both streams of heat from the water jacket and the exhaust can be further enhanced through an Organic Rankine Cycle (ORC). This process allows further heat recovery from low temperature sources to be converted into useful work, that can itself be converted into electricity and therefore improve the overall efficiency of the plant.
