C312 THE RESEARCH OF CALCULATING METHOD OF HEAT ECONOMY OF AUXILIARY SYSTEM FOR THE COAL-FIRED POWER UNIT

Abstract

Auxiliary system is important part in thermodynamic system of coal-fired power plant. Based on the research on the characteristics of auxiliary system, and by using the energy balance theory, a general formula for the heat economy of steam-water auxiliary system is derived in this paper. The result of application shows that the calculating method discussed in the paper is more precise and scientific, and possesses the characteristics of convenience and universality use.
