Environmentally acceptable electric energy generation process and plant

Process for salvaging waste and device for preparing said waste

Process for operating a coal-based fluidized bed combustor and fluidized

A combined gas and steam turbine plant includes a coal gasification system having a heat exchanger device and preferably a gas scrubber connected downstream of the heat exchanger device. A gas turbine part is connected downstream of the coal gasification system and has an exhaust gas turbine. A steam generator system receives exhaust gas from the exhaust gas turbine and has an economizer heating surface, an evaporator heating surface, and superheater heating surfaces. A steam turbine part is connected to the steam generator system and has a high-pressure feedwater system. The heat exchanger device of the coal gasification system is connected in such a way that it directly transfers or gives up thermal energy for feedwater heating or steam generation to the high-pressure feedwater system of the steam turbine part.

Combined gas and steam turbine plant with coal gasification

Process and plant for generating steam using waste heat

A gas and steam turbine power plant has a gas turbine with a gas side, a waste heat steam generator having a steam side and being connected downstream of the gas side of the gas turbine, and a steam turbine connected to the steam side of the waste heat steam generator. A super-charged, coal-fired steam generator has an exhaust gas vent line connected to the gas turbine. The coal-fired steam generator includes at least one substoichiometrically operated fluidized bed furnace system, an integrated dust separator connected downstream of the at least one fluidized bed furnace system, and a steam generator slag tap or wet tap furnace having burners with a gas side connected downstream of the dust separator.
