[0001] The invention relates to a high-temperature pellet sensible heat recovery device and a recovery method. Background technique
[0002] At present, there are many ways to recover sensible heat from high-temperature pellets, such as the sensible heat recovery process of the water-cooled beam of the pelletizing shaft furnace, the sensible heat recovery process of the pellet tank type, and the sensible heat recovery process of the closed chain plate machine, etc. The water-cooled beam sensible heat recovery process of the pellet shaft furnace is to change the large and small water beams of the pellet shaft furnace from the forced circulating water cooling to the vaporization cooling method, so that the high-temperature pellets can directly exchange heat with the vaporization cooling beam, and reduce the circulation of water , to produce low-pressure steam. However, the transformation period of the shaft furnace of this process is long, and the heat transfe...
