Arrangement structure of heating surface of coke oven gas boiler in coal chemical industry

The invention provides an arrangement structure of a heating surface of a coke oven gas boiler in the coal chemical industry. Coke oven gas is used as a fuel of the boiler, so that the boiler operates efficiently, the industrial structure is reasonable and the structure is very economical. The structure comprises a hearth and is characterized in that a high temperature superheater and a low temperature superheater are sequentially arranged in a horizontal flue part at the outlet of the hearth, a coal saver and an air preheater are sequentially arranged in a vertical flue at the tail part from top to bottom, and a combustion chamber is arranged on the lower part of the hearth.
