Cooling circulating water system of 1260 blast furnace body and upper tower

The object of technology improvement is the normal-pressure and upper-tower cooling circulating water system of the 9# 1260 blast furnace body. The cooling water is mainly used for heat exchange and cooling of the cooling wall, hot blast heater and motor oil cooler. Three 1120kW pumps are used, two in service and one for standby. The upper tower water system is equipped with three 500kW pumps, two in service and one for standby. After system optimization and adjustment, six high-efficiency pumps are used, and the operating mode is unchanged. According to the acceptance results, 10,210,000KWH power can be saved annually.
