Research and application of water abstraction problem of power station boiler surplus heat utilization system

Abstract

Abstract:

Flue gas surplus heat utilization and emission reduction technology of power plant boilers have achieved remarkable results and has been widely used. Studying on water abstraction balance, obtaining inlet and outlet pressure of the electric control valve by theoretical calculation and considering the conditions of flow and pressure, the electric control valve can be reasonably selected, which can ensure the flow direction. The problem of reverse flow in the water abstraction in project reconstruction is solved. The stability and safety of the system operation is ensured.

Key words:

further utilization of surplus heat, energysaving reconstruction, water abstraction balance, control valve, flow characteristic
