蒸气供热系统的凝结水回收,是蒸气供热系统节能的一个重要方面。目前许多系统的凝结水回收率很低,甚至不到百分之三十。如果以供汽量为每小时10吨的系统为例,每小时因损失凝结水所浪费的热量约511×10~3千卡,折合标准煤120公斤之多。实际上,多年来由于凝结水大量损失,引起锅炉给水处理设备额外增加、锅炉容量扩大及相应增加的能源消耗是很可观的,所以损失凝结水造成的能源浪费不止上面所列举的数值。如果把凝结水回收率提高到80～90％
Condensate recovery in steam heating systems is an important aspect of energy savings in steam heating systems. Many systems currently have very low condensate recovery, even less than 30 percent. If we take a system with a steam supply of 10 tons per hour as an example, the waste of heat due to the loss of condensate per hour is about 511 × 10 ~ 3 kcal, equivalent to as much as 120 kg of standard coal. In fact, over the years due to the large loss of condensate, the additional boiler water treatment equipment, the expansion of the boiler capacity and the corresponding increase in energy consumption are considerable, so the energy waste caused by the loss of condensate is not just the values listed above. If you increase the condensate recovery to 80 to 90%
