System for recovering pressure and sensible heat from blast furnace gas
with use of dry-type dust collector
摘要:
A system for recovering as power the pressure and sensible heat of the gas discharged from the top of a blast furnace by guiding the gas to a dry-type dust collector for the removal of dust while maintaining the gas at the furnace top pressure and introducing the gas into a turbine for expansion. To protect the dry-type dust collector when the gas is run off from the furnace at an abnormally high temperature, a gas channel extending from the furnace to the dust collector is provided with at least one injector, which injects a cooling fluid into the gas in response to a signal from a temperature detecting sensor disposed close to the gas outlet of the dust collector. The sensor which is positioned near the dust collector outlet detects the temperature without the time delay attributable to the deposition of dust. With use of the dry-type dust collector, the gas can be fed to the turbine almost without cooling for the recovery of an increased amount of power.
