UNIT FOR HEATING COMPRESSD AIR

摘要

A unit for heating compressed air includes an air heater of recuperative type, this includes loop heat exchange pipes installed in the gas duct, the loops of those are placed one in another with formation of flat screens, and supply and discharge air collectors. The unit includes a unit for production of high-temperature mixture due to low-calorie fuel burning placed before the inlet of the heat exchanger, fan for supply of air for burning to the unit for production of the high-temperature mixture, smoke exhauster to overcome the resistance of the gas duct. At that the heat exchanger is arranged as modules of screen blocks that form the gas duct, and the screen blocks are assembled of the packs of flat screens.
