How to classify waste heat boiler according to waste heat properties

Waste heat boiler is divided into the following seven categories according to the nature of waste heat: high temperature flue gas waste heat: it is a common way, which is characterized by large output, concentrated production point, strong continuity, easy to recover and use, its heat accounted for 40~50% of the total heat, the waste heat boiler recovery heat, can be used for production or domestic heat and power generation.

High temperature slag waste heat: such as blast furnace slag, converter slag, electric furnace slag, etc., the slag temperature above 1000℃, it takes away the heat accounted for 20% of the total heat. High temperature product waste heat: such as coke oven coke carbon, ingot billet, high temperature forgings, etc., it is generally temperature. It's high and contains a lot of waste heat.

Waste heat from combustible waste gas and liquid waste: such as blast furnace gas, recycled waste gas from catalytic cracking in oil refineries, black liquor from paper mills, etc., they can all be used. Chemical reaction waste heat: such as metallurgy, sulfuric acid, phosphoric acid, fertilizer, chemical fiber, paint and other industrial sectors, there are a lot of chemical reaction waste heat.

Cooling medium waste heat: such as the water jacket of industrial furnaces and other cooling equipment discharged a lot of cooling water, the steam produced by various vaporization cooling equipment contains a lot of waste heat, and they can be used reasonably. Condensate waste heat: the physical sensible heat that the steam used in the production process of various industrial departments has when the condensation is reduced after the industrial process.
