一、印染厂散失的大量热能气和水是印染厂加工织物必不可少的两大热源,但其热能的利用率却相差甚多,远远没有充分利用。这些热能的损耗主要是排放水带走的热量、烘燥排气带走的热量及烟囱排烟的热量。以一些中小容量的油炉来看,其排烟温度多在250℃～400℃,以热定形机、焙烘机、热熔染色机的排风温度来看,多在180～200℃,大量余热未被利用。经测试,一般在油炉上的热效率达70—80
First, the loss of a large number of thermal dyeing and printing plant thermal gas and water is an essential dyeing and printing fabric processing fabric two major sources of heat, but the utilization of thermal energy is quite different, far from fully utilized. The loss of these heat is mainly the heat taken away by the water, the heat removed by the drying exhaust and the heat of the smokestacks. To some small and medium capacity oil furnace, the exhaust temperature of more than 250 ℃ ~ 400 ℃, heat setting machine, baking machine, hot melt dyeing machine exhaust temperature point of view, mostly in 180 ~ 200 ℃, a large number Waste heat is not used. Tested, the general thermal efficiency in the oil furnace up to 70-80
