Abstract
PURPOSE: To control the quantity of water gas generation so as to promote blowing- out efficiency and to improve safety of blowing-out operation of a blast furnace, by controlling the quantity of cooling water injected into the furnace according to the discharging gas temp. at the furnace top.
CONSTITUTION: During blowing out of a blast furnace, raw materials charged into the furnace, e.g., red-hot coke j etc. are cooled with cooling water h, thereby producing water gas by the reaction of the red-hot coke with water. The water gas is diluted with steam d, press. controlled by a bleeder e, and is released to the air. Because a constant relation is present between the released gas temp. and the water gas quantity, the injecting quantity of the cooling water is controlled so as to keep constant the released gas temp. at the top by measuring continuously the temp. of the furnace top gas, which is discharged safely through the bleeder e. If the temp. of the discharged gas is reduced to a temp. lower than the prescribed temp., too much water gas is being produced, so that it is not controlled by the bleeder, and a dust collector l or a water seal m may sometimes be damaged. Hence the injecting quantity of the cooling water must be decreased in order to restrain the production of water gas, hereby the blast furnace is blown out safely and efficiently.
