Abstract

The embodiment of the invention discloses a boiler wet operation water supply control method and device and a computer storage system. The method comprises the steps that the current water level value of a water storage tank of a steam-water separator is obtained; the opening degree of a recirculation pump flow adjusting valve is adjusted according to the current water level value and the water level set value of the water storage tank so as to control the water level of the water storage tank; the current flow value of the inlet end of an economizer is obtained; the opening degree of a starting adjusting valve is adjusted according to the current flow value, the flow set value of the inlet end of the economizer and the current recirculation flow value of the recirculation pump flow adjusting valve so as to control the water supply amount of a boiler; and the flow value of the inlet end of the economizer is adjusted according to the current recirculation flow value of the recirculation pump flow adjusting valve and the water supply amount of the boiler so as to control the water level of the water storage tank. By means of the embodiment, the water level of the water storage tank can be adjusted more quickly and sensitively, and the water level of the water storage tank is kept stable.

Description

technical field [0001] This specification relates to the field of safe operation of boilers, and in particular to a method, device and computer-readable storage medium for controlling water supply in wet-state operation of boilers. Background technique [0002] The supercritical steam turbine generator set is equipped with a once-through boiler, and a reliable automatic water supply control strategy is one of the important control strategies to ensure the safe and stable operation of the once-through boiler. When the supercritical generator set is running under wet conditions during boiler start-up and low load, in order to ensure the safety of the boiler water wall, a start-up system needs to be put into use to maintain the inlet flow of the economizer. The start-up system of the once-through boiler includes the form of setting the boiler water circulation pump (Boiler Cycle Pump, BCP). The automatic water supply control of the existing once-through boiler with BCP pump un...
