FLUE GAS HEAT RECOVERY BY HOT PIPE EXCHANGER AND ITS THERMODYNAMIC ANALYSIS[J]. Thermal power generation, 1993, (4): 17-21. DOI: 10.19666/j.rlfd.1993.04.004.
This paper presents a hot pipe heat exchange system which is used to heat the condensate of regeneratine system or cold air by recovered heat from boiler flue gas. With this system being used the temperature of flue gas can be greatly reduced
the efficienev inproved and energy saved. In the meanwhile low temperature corrosion and ash blockage in the back-end surfaces of boieer can be prevented.
