Abstract

PURPOSE: To prevent a bad influence by an abnormal high temperature of a blast furnace gas on a dry type dust remover by a method wherein a cooling fluid is supplied in accordance with a temperature increase and the ratio to a gas passage when a temperature of a gas outlet port of the dry type dust remover for the blast furnace gas has exceeded a set value.
CONSTITUTION: Gas B exhausted from the top of a blast furnace 1 is led to a gas holder 6 through a route passing through a septum valve 5 and another route passing through a power generating installation 7 after the contained dust has been removed through a coarse dust remover 3 and a dry type dust remover 13. When a sensor 16 provided at the outlet of the dry type dust remover 13 detects an abnormal temperature of the gas B, a control unit 18 arithmetically operates the temperature increase and its ratio to select operations of a specified quantity of cooling fluid ejectors 15A, 15B and 15C to control a quantity of a cooling fluid to be ejected to a gas passage 2.
