Waste no more

Broiler farm litter mixed with woodshavings and poultry droppingsmake an excellent fuel for generating power, contends Fibrogen Ltd, aUK-based developer, builder andoperator of power stations (Technology Partnership Initiative. issue 7).

Fibrogen buys poultry litter andtransports the same to covered storage pits in the power station. Loadedthrough conveyor belts into the furnace, the fuel is burnt at temperatures greater than 850'C. The furnace heats up water in the boiler toproduce steam which drives a conventional steam turbine linked to agenerator with an output of 15.1MW. The net output is supplied to a33 kilovolt power line which connects the power station to the localelectricity sub-station.
