ABSTRACT:
A power plant for burning a fuel at a pressure exceeding atmospheric pressure, in particular a PFBC power plant with a bed vessel enclosed in a pressure vessel, includes a plurality of valves in a hot gas pipe between the bed vessel and a turbine, and an air duct between a compressor and the bed vessel, and in a short-circuit connection between the ducts which are constructed as a single valve unit located in a valve housing. Arranged centrally in the valve housing is a cylinder providing passage for gas to the turbine and an annular channel is formed between the valve housing and the cylinder for compressed air from the compressor. At least one valve is provided in the cylinder and the channel includes a plurality of valves arranged in parallel. Between the annular channel and the cylinder a short circuit connection is provided having a plurality of valves. The valves in the air duct and the valves in the short circuit connection have valve discs arranged on a common spindle. The valve in the air duct can function as a non-return valve should the operating device of one of the valves fail to operate.
