Chemical reaction furnace system

摘要

A chemical reaction furnace system having a reaction furnace, a reaction gas exhaust flowpath, and a gas scrubbing device in the exhaust flowpath and having a capability of controlling the furnace top pressure is characterized by the provision of a turbine in the exhaust flowpath downstream from the scrubbing device and being operable to recover energy in the reaction gas, a gas bypass flowpath branched from the exhaust flowpath at a point thereof between the scrubbing device and the turbine and bypassing the turbine, turbine inlet pressure controlling means, and a septum bypass valve installed in the bypass flowpath and operating in response to control by the turbine inlet pressure controlling means to control the turbine inlet gas pressure.
