在现今采暖工程中,凝结水的回收,由于量少、分散,又无先进的回水装置,往往被人们忽视。据有关部门统计,我国目前有疏水器250万只,严重失灵的约占30％。一只失灵的疏水器一年损失热量相当于7吨标准煤。要回收凝结水的巨大热最,除了提高疏水器的质量外,更重要的是在采暖设计中尽量减少疏水器,采用集中回水装置,将凝结水输送到锅炉房或热交换中心继续使用。 In today’s heating projects, the recovery of condensate is often overlooked because of the small amount, dispersion, and lack of advanced water return devices. According to relevant department statistics, there are 2.5 million steam traps in China, accounting for about 30% of serious failures. A failed steam trap loses about 7 tons of standard coal a year. To recover the huge heat of condensate, in addition to improving the quality of the steam trap, it is more important to minimize the steam trap in the heating design, use a centralized water return device, and transport the condensate water to the boiler room or heat exchange center for continued use.
