The cooling water system supplies water for the operating equipments in two ways. One way is from the main shop cooling water system and to cool down ball mill outlet slurry pump, limestone slurry storage tank and pump, crusher lubrication station and directly return to main shop cooling water system. The other way is to supply water for #3, #4FGD and other common system (except limestone slurry preparation system and limestone conveying system), which is formed by 2 cooling water booster fans (one for use and one for standby) and relevant pipe and instruments. The cooling water from the booster fan is to chill the booster fan lubrication station, absorber slurry recirculation pump. Oxidation fan and limestone slurry feed pump.
In normal situation, one pump operates and the other is for standby. When cooling water pump outlet main pipe pressure is under 3bar, interlock start the standby pump. All cooling water will be returned to main water cooling system.
