摘要
根据600MW机组热平衡图,定性地分析了汽轮机热力系统部分热平衡关键点数据变化对煤耗的影响,并通过不同工况下的数据,定量地分析和计算出相应的机组热耗率数值,通过和设计工况的热平衡数据对比,得出电厂相应的煤耗率和机组热效率差值。在对标过程中,通过分析关键点的数据变化,可以找出机组调整和进行技术改造的关键环节,降低电厂煤耗。
Based on the heat balance diagram of 600 MW unit, the key data points in rated condition were analyzed, and relevant thermal efficiency data can be obtained by calculating according to the key data points. The coal consumption rate and unit thermal efficiency will vary with the variation of the field operation parameters. Therefore, it is can find that in which respects the unit need adjustment or reformation by analysis of key points data variation, and the key link for decrease the coal consumption rate of power plant can be grabbed. The emphasis of this paper is analysis of coal consumption data of steam turbine thermal power system, the coal consumption rate in this paper was obtained by heat balance calculation according to the relevant data of heat balance diagram.
