摘要
Abstract
Auxiliary steam-water system is an important part of thermal system of power generator networks. The calculation of auxiliary steam-water rate of flow on the influence of coal consumption rate has an importaht practical ' significance. This article proposed a new method of calculating auxiliary steam-water rate of flow on the influence of coal consumption rate. It is based on the unified physical model and mathematical model of the analysis of thermo- economics and has the aid of gradient operator to build a calculation equation about the influence of auxiliary steam-water rate of flow on coal consumption rate. This equation was based upon intensity matrix. By example-calculating of typical working condition, the article tested and verified the correctness of this model. By this method, this was no need to build an energy-balance equation and a mass balance equation of thermodynamic system and has other advantages, for example, the easy derivation, little amounts of calculation, high accuracies and universality. Then, it presents a new tool of auxiliary steam-water system quantitative calculation and reaching energy conservation and lower energy consumption of thermal power generator networks.关键词
