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 water-tube type boiler of double(single) drum, namely , the boiler of supplemental combustion and the boiler without supplemental combustion. These two types of boiler are applicable to the coking industry. The layout of boiler is classified into two types: the traditional, horizontal type and the new vertical type , among which the vertical layout of boiler has novel structure and advanced property. It is a new patent of waste heat boiler for the waste gas of coking exclusively developed by our company. The boiler with supplemental combustion utilized the automatic coke oven 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 gs and enters into the boiler to be converted into rated steam.
The waste gas is exhausted through the boiler slag tube bank, super-heater, convection tube and steel pipe coal economizer, enters into the desulfurizing and de-dusting installation at the bottom; and then it is exhausted to the atmosphere by the induced draft fan through the chimney. The solidified slag bank is dispersed from the water-wall tube. The structure of the super-heater is the horizontal suspension structure, with high
temperature area and low temperature is. The super-heater is cooled by surface type of cooling or water. The convection bank adopts the in-line arrangement. In the middle of the convection bank, there is baffle wall through the multiple baffling; the convection bank can improve the velocity of the flue gas, thus forming the effective horizontal scouring and
improving the heat transfer capacity of the convection band. The coal economizer is the pipe coil bend economizer, adopts the transversal flow staggered layout. The unique membrane-type wall flue gas channel wall of the boiler can increase the heating surfaced, improve the seal and security of the boiler, as well as compact the structure of the 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 function 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 function 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.
The main specification is as following: rated steam output 5-75t/h, rated steam pressure 1.0-9.8Mpa
