摘要
分析了烟气中水蒸气体积分数、烟气露点的影响因素,探讨了燃气锅炉排烟温度、过剩空气系数对烟气热损失的影响。结合算例,对采用烟气冷凝余热回收装置提高燃气锅炉热效率进行了理论计算。
The influencing factors of steam volume fraction and dew point of flue gas are analyzed The influence of flue gas temperature of gas-fired boiler and excess air coefficient on flue gas heat loss is discussed. The theoretical calculation for improving the thermal efficiency of gas-fired boiler by recovery device of condensation heat from flue gas is carried out with calculation example.
