Abstract

The invention discloses a waste heat boiler system for an electric furnace. The waste heat boiler system comprises a multi-section heating surface, wherein the heating surface is modularized, and theheated surface and a steam drum form a steam-water system loop through a rising pipe and a falling pipe. According to the waste heat boiler system for the electric furnace, the problem that the settling efficiency of waste gas dust of the electric furnace is low is solved, and efficient settlement of the flue gas dust of the electric furnace is achieved; meanwhile, normal electric furnace smeltingproduction is not affected, on-line replacement of the heating surface of a waste heat boiler for the electric furnace is achieved, and the problem of on-line replacement of the heating surface is solved; and heat in the waste gas generated by electric furnace smelting is utilized more efficiently, generated steam is used for workshop production, heating, power generation and the like, and the gain value is achieved.

Description

technical field [0001] The invention relates to the technical field of electric furnace steelmaking waste heat utilization, in particular to an electric furnace waste heat boiler system. Background technique [0002] Electric arc furnace steelmaking is a steelmaking process in which electricity is used as energy. It is a short-process steelmaking process and mainly uses scrap steel as raw material. A large amount of high-temperature dusty flue gas is produced during the steelmaking process, and the sensible heat of the flue gas accounts for more than 10% of the total energy consumption of electric furnace steelmaking. At present, the domestic flue gas cooling method is mainly water-cooled. The traditional cooling method consumes a lot of electricity and water, and a large amount of high-temperature flue gas heat is discharged into the atmosphere, which not only wastes energy, but also has adverse effects on the environment. [0003] Inadequacies of traditional technology: 1...
