... studied to provide guidance to prevent fouling ammonium bisulfate (ABS) and the acid dew point of the flue and corrosion of rotary air preheaters. The results show that the gas, which in turn will cause serious fouling of downstream heat main path to generate ABS is the reaction between H2SO4 and exchange...

.... The energy-saving effect of flue gas waste heat cascade utilization system is restricted by factors such as acid dew point temperature, ammonium bisulfate (ABS) deposition inside the air preheater, etc. Based on the performance analysis of regenerative air preheater and ABS deposition law, considering...
