Air preheater was installed on cracking furnace of No.2 vinyl chloride device in Qilu Chlor -alkali Plant to recover waste heat from convection section of the cracking furnace and heat the required air for combustion, which decreased the consumption of fuel gas for the crack-ing furnace.Running data showed that per unit fuel gas consumption was decreased by 3 kg/t and cost was saved about ￥ 7.36 million/a after the air preheater was put into use.
