本世纪七十年代以来,不少国家致力于对喷流热交换器的研究,这主要是该换热装置有显著的经济效益所决定的。喷流换热装置主要用于辊底式、步进式、输送带式等明火连续加热炉。苏联的一些工厂首先将喷流热交换器用在加热炉的空气予热上。它是利用特制的板栅或带孔的管子的孔隙,使热介质从法向直接喷射到换热器的金属表面,形成一种湍流,从而强化热交换效果,以提高热效率。 Since the seventies of this century, many countries have devoted themselves to studying the jet heat exchanger, which is mainly determined by the obvious economic benefits of the heat exchange device. Spout heat exchange device is mainly used for roller bottom, step, conveyer type open flame continuous furnace. Some factories in the Soviet Union first use the jet heat exchanger to preheat the air in the furnace. It is the use of special grid or perforated pipe pores, the heat medium from the normal jet directly to the heat exchanger metal surface, forming a turbulent flow, thereby enhancing the heat exchange effect, in order to improve thermal efficiency.
