Research Based on the Mid-Point Enthalpy of Supercritical Unit Feed-Water Control Circuit

Article Preview

Abstract:

Introduced the supercritical unit boiler feed-water supply system of once-through boiler’s structure and characteristics, and the feed-water supply system control principle and control strategy. Analysis of the system all controlled object and based on the interaction between the mid-point in the feed-water supply system enthalpy control of the regulatory process and problems, and put forward the corresponding optimization measures, and simulation research, the simulation results show that the feed-water supply system to improve the quality of the feed-water supply system adjustment, the main adjust the parameter of good quality, safety and economy got the reliable guarantee.
