摘要
针对烟气换热器壁面温度会低于排烟露点的情况,提出了正压通风燃气锅炉排烟热能利用系统。对排烟热能回收换热器热质交换进行了理论分析,提出了排烟热能回收换热器的设计计算过程,并对排烟热能利用系统进行了实验研究,阐述了工程应用中应注意的问题。
Aimed at the fact that the wall temperature of heat exchanger is lower than the dew point of flue gas, the thermal energy utilization system for flue gas of positive draft gas boiler is proposed. The theoretical analysis on heat and mass transfer of the heat exchanger is made, the design calculation method of the heat exchanger is put forward, the experimental study on the system is conducted, and problems that need to be paid attention for the project application are described.
