锅炉排污过程中,由于带有较高的热量,如果不加任何处理措施,则会浪费很大的热能。所以,设置连续的排污装置与热交换器相连,将排污的热量回收到锅炉给水中,使给水温度上升,从而可以节省燃料。另外,与间歇排污相比,连续排污不仅仅节能,而且可以将炉水溶解性物质的浓度、吸收药品浓度等保持稳定,这对锅炉水管理方面来说也是有利的。[例]在占给水量10%(5 56 kg/h)的排污运行的锅炉当中,试求排污出水温度在70℃时,热量回收情况下的燃料节省率。
Boiler sewage process, due to the higher heat, without any treatment, it will waste a lot of heat. Therefore, the provision of a continuous blowdown device connected to the heat exchanger, the sewage heat recovery to the boiler feed water, the feed water temperature, which can save fuel. In addition, compared with intermittent sewage, continuous sewage not only energy saving, but also the furnace water soluble substance concentration, drug concentration absorption and other stability, which is also beneficial to the boiler water management. [Example] In the case of a boiler operating at a blowdown of 10% (566 kg / h) of water supply, the fuel saving rate in the case of heat recovery is sought when the blowdown water temperature is 70 ° C.
