摘要： In the event of an operational disturbance in a turbine-compressor unit of a PFBC plant, the turbine and the compressor are isolated from the bed vessel of the plant by closing a valve in the gas supply conduit to the turbine and by closing a valve in the conduit leading from the compressor. At the same time a valve is opened in a by-pass conduit between the compressor and the turbine. Combustion air is allowed to escape into the atmosphere via one or more blow-off valves. The bed vessel and/or a space between the pressure vessel and the bed vessel are supplied with inert gas in such a way that combustion in the bed is damped down.
