New power generation technology based on gasification of low rank coal
- HRL Ltd., Victoria (Australia)
Low rank coals form an important part of the fossil fuel resources of many economies, and they have been used successfully for power generation. Recently, their use has been questioned on economic and environmental grounds because the high moisture content of low rank coals results in large boiler sizes and low thermal efficiency. Research has been initiated by the State Electricity Commission of Victoria with the objectives of reducing the cost of electricity and CO{sub 2} emissions from brown coal power stations. This research has led to the development of a new process based on integrated drying and gasification of coal for use in a gas turbine combined cycle. Studies have been made on pressurized coal drying, coal gasification, hot gas filtration, and pressurized combustion. The results of those studies, along with economic evaluations, indicate that the technology is technically feasible and economically attractive when compared with alternative technologies for power generation. The technology has great potential for countries wanting to make use of low rank coal resources in a way that will meet emerging requirements for reducing environmental pollutants from power generation. The next stage of developing the technology is the construction and operation of a 10-MW scale facility in the Latrobe Valley. The design and construction work for this began in July 1994.
