Abstract

The invention relates to the technical field of superheater temperature lowering for main steam temperature control, in particular to a superheater temperature lowering water supplying system. The superheater temperature lowering water supplying system comprises a high-pressure heater, a superheater and a boiler coal economizer; an inlet of the high-pressure heater is connected with an outlet of aboiler water feeding pump through a first water inlet pipeline; the outlet of the boiler water feeding pump communicates with a water inlet of the superheater through a second water inlet pipeline, and therefore the cold temperature lowering water adjusting process is achieved; an outlet of the high-pressure heater communicates with a water inlet of the boiler coal economizer through a first communicating pipeline; and the outlet of the high-pressure heater further communicates with the water inlet of the superheater through a second communicating pipeline, and therefore the hot temperature lowering water adjusting process is achieved.

Description

technical field [0001] The invention relates to the technical field of superheater cooling with main steam temperature control, in particular to a superheater desuperheating water supply system. Background technique [0002] The boiler superheater desuperheating water is used to reduce the temperature of the steam entering the high temperature superheater, protect the high temperature superheater, and at the same time adjust the temperature of the steam entering the steam turbine to maintain a constant main steam temperature and ensure the safe operation of the unit. [0003] Although the existing boiler superheater desuperheating water supply system can achieve the effect of controlling the temperature of the main steam, it has the problem of high energy consumption and no energy saving. In view of the existing problems, it is of great significance to design an energy-saving boiler superheater desuperheating water supply system. Contents of the invention [0004] The pur...
