DEVICE FOR RECOVERY OF HEAT OF EFFLUENT CONVERTER GASES Russian patent published in 2013 - IPC C21C5/38 

FIELD: power engineering.

SUBSTANCE: device comprises a cooler of converter gases, a gas cleaning system, compressors for converter gas compression, a gas holder of converter type, a recuperator installed in a gas flue of an oxygen converter for heating of natural gas, switching and isolating valves and a system of automated control of processes in a device. The device is equipped with a mixer of steam and natural gas, a heater of a steam and gas mixture, an afterburning chamber, a reactor of steam conversion, a gas turbine, comprising a compressor, a combustion chamber, a recuperator for air heating and an electric generator. Besides, the mixer of steam and natural gas is connected with the heater of the steam and gas mixture, and the heater of the steam and gas mixture - with the reactor of steam conversion by pipelines of the steam and gas mixture, the gas holder is connected with the afterburning chamber by the pipeline of converter gases, and the reactor of steam conversion is connected by a pipeline of synthetic gas with the gas turbine.

EFFECT: increased efficiency of using chemical and physical heat of effluent converter gas.
