ABSTRACT:
A thermal power plant comprises a thermal prime mover and a supercharged gas generator for generating producer gas from coal which, following separation of fly ash and sulphur, serves as fuel for the power plant. A charging group for the gas generator consists of coupled air compressor and gas turbine units, the compressor unit providing compressed air for operating the supercharged gas generator and the gas turbine unit being driven by unburned producer gas from the output of the supercharged gas generator, and a dry dust collector for the fly ash is incorporated in the flow path of the producer gas either ahead of the charging gas turbine or just after the first row of its moving blading. In order to also remove the sulphur content from the producer gas, an injector for a reagent which chemically binds the sulphur is provided in the flow path of the producer gas between the supercharged gas generator and the dry dust collector whereby the chemically bound sulphur is then removed from the producer gas together with the fly ash in the dry dust collector.
