Abstract:

The heat tube technology and advantages of heat tube exchanger have been introduced and analyzed in the text. The heat tube air preheater has been checked to be used for low temperature emission heat recovery of tube furnace. The thermal work and benefit have been calculated. By the research conclusion, the heat tube technology can improve 10.21% heat capacity of heating furnace, save 5.08×106m3 COG and reduce 2.9×107m3 emission discharge per year and achieve marked effect of conserve energy and reduce emission.
