Abstract:At present, there is still some waste heat in the production of Guixi Smelter that has not been effectively used. Through the transformation of waste heat recovery technology, the waste heat of the air compressor and the waste heat of the converter water jacket are combined with the process and production without affecting the production. The effective recovery of the middle part of the waste heat not only reduces the waste of energy, but also saves a certain economic cost for the factory, and also provides strong support for environmental protection.
