ZG Coking Waste Heat Boiler
The new patent of waste heat boiler for the waste gas of coke has avoided the defects of the traditional horizontal waste heat boiler with one flue gas channel or multi flue gas channel. It can organically combine the various components of the boiler without the change of their functions, centralize the heating surface, simplify the structure in the boiler and achieve the multi-function composite of the various components. This new patent of waste heat boiler for the waste gas of coke has the functions of high efficiency heat transfer, two-level of soot separation in the boiler. It achieves the advanced level in China because of its compacted structures, novel structure, low cost, small floor area, environment protection and energy conservation.
During the process of coking production, the coking plant will produce a lot of waste gas with the temperature of 550-950℃. For further recycle of the waste gas, our company developed two types of horizontal natural circulation waste-tube type boiler of double (single) drum, namely, the boiler of supplemental combustion and the boiler without supplemental combustion. These two types boiler are applicable to the coking industry. The layout of the boiler is classified into two types: the traditional, horizontal type and the mew vertical type, among which the vertical layout of boiler has novel structure and advanced property. It is a new patent of coking waste heat boiler for the waste gas of coking exclusively developed by our company. The boiler with supplemental combustion utilizes the automatic coke even gas burner. Firstly, the coke oven gas is burned inside or outside of the waste heat boiler, and then mixed with the waste gas of coking; it becomes the high temperature flue gas and enters into the boiler to be converted into rated stream.
The waste gas is exhausted through the boiler slag tube bank, super-heater, convection tube bank...
