| Abstract: | In view of the problems of high unit gas consumption and low safety factor in the industrial naphthalene distillation unit of 360000 t/a tar processing plant of Shanxi Holeco Chemical Co.,Ltd.,the exhaust gas temperature of the tubular furnace was reduced from 450℃to less than 140℃by replacing the burner,adding an air preheater at the top of the tubular furnace,and adding automatic ignition device and quick shut-off valve in terms of automation upgrading.The temperature of combustion supporting air was increased from 30℃to 280℃,the thermal efficiency of tubular furnace was increased from 68.5%to 81.4%,the unit consumption of gas for tar processing was reduced by about 0.61 m3 per ton,and the operation convenience,safety and stability of heating furnace were improved. |
