Zusammenfassung:	PROBLEM TO BE SOLVED: To suggest an emergency stop method of a pressurized fluidized bed furnace system which suppresses operation failure of a compressor of a supercharger, and suppresses occurrence of a harmful substance caused by incomplete combustion of a processed material remained in a pressurized fluidized bed furnace.SOLUTION: After a pressure in a pressurized fluidized bed furnace has abnormally increased, by performing a compressed air supply stop process for closing at least one of an auxiliary air supply channel connected to an auxiliary fuel combustion device, or a channel connecting a combustion air supply pipe with a compressor, and a compressed air supply start process for connecting a start burner of the pressurized fluidized bed furnace and at least one channel for connecting the compressor, the problem is solved.
