The principle of waste heat boiler is that high temperature flue gas is generated by burning fuel, gas and coal to release heat. The high temperature flue gas enters the furnace first, then the waste heat recovery device in the front smoke box, then the pyrotechnic tube, and then the waste heat recovery device in the flue of the rear smoke box. The high temperature flue gas turns into low temperature flue gas and is discharged into the atmosphere through the chimney. The manufacturer of incinerator waste heat boiler tells you that this kind of boiler is relatively energy-saving because it greatly improves the utilization rate of heat released by fuel combustion.

1. High temperature flue gas waste heat: it is a common form, characterized by large output, concentrated production points, strong continuity, easy recovery and utilization, and its heat taken accounts for 40~50% of the total heat. The heat recovered by the waste heat boiler can be used for production or domestic heat and power generation.

2. High temperature slag waste heat: such as blast furnace slag, converter slag, electric furnace slag, etc. The slag temperature is above 1000 ℃, and the heat taken away by it accounts for 20% of the total heat.

3. High temperature product waste heat: such as coke oven coke, steel ingot billet, high temperature forging, etc., which is generally very high and contains a lot of waste heat.

4. Waste heat of combustible waste gas and waste liquid: such as blast furnace gas, catalytic cracking regeneration waste gas of oil refinery, black liquor of paper mill, etc., they can be used.

5. Waste heat of chemical reaction: industrial departments such as metallurgy, sulfuric acid, phosphoric acid, fertilizer, chemical fiber, paint and so on all produce a large amount of waste heat of chemical reaction.

6. Waste heat of cooling medium: for example, a large amount of cooling water discharged from cooling devices such as water jackets of industrial furnaces and kilns, and steam produced by various vaporization cooling devices contain a large amount of waste heat, which can be reasonably utilized.

7. Condensate waste heat: the physical sensible heat of steam used in the production process of each industrial department when condensing and reducing after the industrial process
