Regulating additional water quantity of coolant water cycle for industrial installation, such as condensing power station

摘要

The method regulates the additional water quantity in a water coolant circulation path in recycle cooling processors in industrial systems, having cooling towers. The state of the water in the basin of the cooling tower is held constant by providing a target value. A target value for the thickening of the water is also provided. The evaporation losses are determined and thus the amount of additional water fed in and the amount of salt water filtered out are controlled in dependence on each other. With no detectable effects on the additional water consumed at constant target values, the amount of additional water fed in and the water filtered out are increased or reduced to keep the state of the cooling water in the cooling tower at an equal ration and to keep the thickening constant.
