Besides, their competitive & cheap price of Furnace Heat Exchangers factory would get you an edge in your own market. Exergy and cost analyses of waste heat recovery from Apr 01, 2019 · The heat recovered from a cement slag blast furnace is treated as a source of heat and used to generate hydrogen and electricity. Fig. 1 illustrates the system and shows the blast furnace waste heat from cement slag. The cement slag exits at 1,500 °C from the blast furnace .The entire amount of heat cannot be recovered from cement slag because of the solidification of slag.
Jun 29, 2021 · The slag ditch is closed, the exhaust steam is introduced into the REGLASS condensing phase change condenser through the exhaust steam fan, and the ambient air and exhaust steam are exchanged in the REGLASS condensing phase change condenser. The wet flue gas is cooled and condensed. After the heat exchange, the air temperature rises. Flue Gas Elimination Project Industrial White Smoke Aug 18, 2021 · Project background:A large amount of white smoke will be generated during the slag flushing process of the 5# blast furnace of a steel plant in Qianan City, which consumes a large amount of slag flushing water every day.After the water evaporates, 90 exhaust steam is generated, causing billowing white smoke and falling water droplets. . The salinity is prominent, affecting the
A method for processing hot, liquid slag includes the steps of:conveying the slag to be processed to an upper region of a granular material forming a fluidized bed that has a temperature below the solidification temperature of the slag; cooling the slag to a temperature below its solidification temperature while simultaneously forming granules; and maintaining the temperature of the fluidized Technologies and fundamentals of waste heat recovery from Oct 01, 2020 · Plate-shaped slag waste heat recovery system. Shigaki et al , developed a new process for waste heat recovery from the slags. In this process, molten slag (above 1673 K) is solidified continuously on the water-cooled rolls to produce plate-shaped slags (temperature:approximately 1373 K, average long side length:50 mm, average thickness:7 mm).
Disclosed is a molten slag residual heat recovery system, comprising a molten slag feed system, a molten slag heat exchange device (22) and a steam-water system, wherein the molte Waste Heat Recovery Technologies IspatGuruJan 10, 2020 · Heat exchangers are normally used to transfer heat from combustion exhaust gases to combustion air entering the furnace. Since preheated combustion air enters the furnace is at a higher temperature, less energy is to be supplied by the fuel.
Apr 14, 2015 · The blast furnace (BF) slag waste heat was recovered by an integrated system stage by stage, which combined a physical and chemical method. The water and coal gasification reactions were used to recover the heat in the system. Based on the first and second law of thermodynamics, the thermodynamic analysis of the system was carried out by the enthalpyexergy diagram.
