Production Practice of Chemical Cleaning of Waste Heat Boiler in Copper Smelter
Waste heat boiler is a device that recovers heat from high temperature flue gas and converts it into steam,which is usually used in the production process of copper flash furnace melting.The steam produced by waste heat boilers has a variety of uses,including waste heat power generation,equipment insulation and steam dryer heating.However,the waste heat boiler is also prone to corrosion,rust and scaling during use,which will reduce its heat transfer efficiency and increase the risk of failure.In order to prevent these problems,the waste heat boiler must be cleaned by regular chemical cleaning.Based on the production practice of chemical cleaning of waste heat boiler,this paper describes the methods of removing all kinds of deposits,rust and grease inside the boiler,so that the cleanliness of the inner surface of the boiler water pipe can meet the normal production requirements,safety risks in the production process of the boiler can be eliminated,and create good conditions for ensuring the normal production of the boiler.
