Abstract
A PFBC power plant, with a vessel containing hot gas considerably exceeding the atmospheric pressure and a blow-off device for rapidly emptying a container containing the hot gas. The blow-off device comprises a heat exchanger which is located between the hot gas vessel and a valve in the blow-off device. Heat-absorbing material in the heat exchanger absorbs heat in the hot gas and reduces the temperature in the gas so as to protect the blow-off valve against thermal shock.
