二、提高供热系统的功效要消除供热系统的漏水、漏汽,加强热水箱、管道和其它各种热力设备的绝热保温,减少凝结水的损失,各用热设备要处于最好的工作状态。有关机构已研究出测量蒸汽泄漏损失的方法,这方法是按照蒸汽汽苗的大小来确定蒸汽通过不严密处发生泄漏而产生的损失。在某一大型石油化工厂,曾有250处发生程度不同的蒸汽泄漏,每小时损失蒸汽5.4吨,消除这些泄漏,用去了12,500美元,但是每年可节约重油1,900吨。在另一工厂进行的调查表明,厂内2,040个冷凝疏水装置中,有263个是完全失修的。修理和换替这些冷凝疏水器,需用2万美元,但每年可节约重油3,530吨。
Second, improve the effectiveness of the heating system to eliminate the heating system of water leakage, leakage of steam, strengthen the hot water tanks, pipes and other thermal equipment insulation, reduce the loss of condensate, the use of thermal equipment to be the best Working status. The relevant agencies have developed a method to measure the loss of steam leakage. This method is based on the size of steam steam seedlings to determine the loss of steam through leaks that are not tightly located. In a large petrochemical plant, there were 250 steam leaks of varying degrees. Steam lost 5.4 tons per hour. Eliminating these leaks cost US$12,500, but it saved 1,900 tons of heavy oil each year. An investigation conducted at another factory showed that 263 of the 2,040 condensation traps in the plant were completely disrepaired. Repairs and replacement of these condensate traps cost US$ 20,000, but save 3,530 tons of heavy oil each year.
