The general topological template and the general steam-water distribution equation of thermal system for the coal-fired power unit

Abstract

The structure of thermal dynamic system for the coal-fired power unit is various and complicated. So, it is comparatively difficult and tedious to set up the steam-water distribution equation. Based on summarizing the characteristics and the steam-water distribution equation of different thermal dynamic systems, the author of this paper puts forward the general topological template of thermal dynamic system with concise structure, which simplifies the course of setting up the steam-water distribution equation. The equation set up on this basis is characteristic of simple structure, being adapted to various thermal dynamic systems, and being easily solved. It provides a new method to the analysis of the thermal energy-economy and consumption difference for the coal-fired power unit with the general topological template and the general steam-water distribution equation.
