Circulating Water Resistance Characteristics of the Thermal Power Plant

Abstract:

The measurement method of the power plant circulating water flow was investigated. When the characteristics of the circulating water system was calculated through characteristic curve intersection, circulating water pumps were generally assumed to be in parallel and the resistance of main pipes was ignored. In addition, the circulating water flow of each unit was considered equivalent. This method was accurate only when the distance of main pipe and circulating water pump is shorter. Therefore, the hydraulic computation method combining with pipe network has been proposed with the long distance condition. This method calculates accurately the circulating water flow of each unit. This research lays the foundation for the optimum vacuum calculation of the whole plant.
