摘要
建立了天然气烟气带冷凝过程热效率计算的数学模型,讨论了排烟温度、空气系数和空气含湿量与热效率的关系,分析了空气预热和补燃对热效率的影响。
A model on calculation of thermal efficiency during flue gas condensation of natural gas is built, the relationship of gas thermal efficiency with flue gas temperature, air factor, and air humidity ratio is discussed, and influence of air preheating and supplementary firing on gas thermal efficiency is analyzed.
