Coke Oven Flue Gas Waste Heat Recovery

Coke waste heat boiler


With the development of coking technology, low-ash, low-sulfur, weak-caking coal is used as the main raw material, a small amount of strong cohesive coal and a small amount of binding additives are prepared, and high-quality foundry coke is made by carbonization after hot pressing. New product. The product has a wide range of applications: it is widely used in the foundry processing industry, automotive, machine tool, and high-grade non-ferrous metal equipment.

The foundry coke production process has the advantages of simple process, low cost, low investment, high yield, and fast comprehensive utilization of energy.

Coke produces a large amount of high temperature flue gas in the carbonization kiln, the temperature is as high as 750 degrees. In the past, these high temperature flue gas were directly discharged into the atmosphere, causing a large amount of heat loss. The waste heat boiler fully absorbs the heat carried by the high-temperature flue gas passing through the furnace, and produces superheated steam required for drying. This type of boiler is a flue-type waste heat boiler, which is widely used in the waste heat recovery of small metal, ceramics, and smelting furnaces, and is especially suitable for coke production industries.

Over the past few years, with the vigorous promotion of national energy conservation and emission reduction policies, through years of research, improvement and improvement, we have used waste heat recovery and utilization to reduce energy consumption and reduce the waste of the three wastes in the coke coking kiln supporting projects. Emissions have achieved huge economic and social benefits.
