摘要
Abstract
Lignite is a kind of low rank coal with high water and ash content, which has low power generation efficiency. In order to improve the efficiency of lignite-fried power system, efficient lignite-fired power system was introduced. Theoretical analysis and calculation were carried out on this system with equivalent heat drop method. Moreover, technical and economic comparison of a 600 MW supercritical power plant was carded out. Through theoretical calculation, this system can reduce power generating consumption rate 12 g/（kW.h） in the benchmark condition stated. Through technical economy analysis, the system can reduce the power system service consumption rate by 0.56% and power supplying consumption rate 15 g/（kW.h）. And at the same time, this system can also reduce pollutants and engineering investment et al. This study finds that burning high moisture content lignite with efficient lignite-fired power system is of great advantage.. This system is energy and water saving and pollutions reduction, which is popularized ＂green＂ lignite-fire power system.关键词
