Spraying / Waste heat recovery and utilization is an important part of the "energy conservation and environmental protection synergy" in industrial production. The spraying process requires efficient heating to solidify the coating, which generates a large amount of waste heat. Waste heat recovery and utilization can convert this discarded heat into hot water, steam or electricity, reducing the energy consumption cost in the spraying process and minimizing carbon emissions. It is a key technological direction for the green transformation of industry. 

Spraying is a process where paint (such as paint or powder coating) is evenly applied to the surface of the workpiece using a spray gun, and then heated and solidified to form a protective film. It is widely used in fields such as automobiles, furniture, and mechanical manufacturing. The heating stage is the main source of waste heat. For the medium and low-temperature waste heat from the spraying process, it is mainly recovered by dedicated equipment and converted into usable energy. Spray / waste heat recovery and utilization not only reduces enterprise costs but also helps achieve environmental protection standards. It is an important development direction in the current industrial field.
