锅炉燃煤量、输入热量和效率变化的关系论证

Demonstration of Relationship between Boiler Fuel Consumption Rate,Heat Input and Efficiency Change

笔者以某些文献和DL/T5240-2010《火力发电厂燃烧系统设计计算技术规程》对锅炉燃煤量变化、热经济性评价的分歧为引子,根据DL/T5240-2010及《锅炉原理及计算》第二版中的锅炉燃煤量计算公式,推导出了在锅炉负荷不变时的三个等式,揭示了锅炉燃煤量变化、输入热量变化、效率变化之间的内在关系。

Based on the divergence of some references and DL/T5240-2010 “Technical Code for Design and Calculation of Combustion System of fossil fuel has fired Power Plant” on the changes of boiler fuel consumption rate and thermal economic evaluation, three formulas under constant boiler load are derived according to formulas for calculating boiler fuel consumption rate of DL/T5240-2010 and the second edition of “Boiler Principles and Calculation”. The internal relationship between the change of boiler fuel consumption rate, heat input and efficiency is revealed.
