我厂锻造车间每小时排放废蒸汽12吨左右,从1963年以来,我们采用四台管束式换热器(每台换热面积为80米~2利用锻锤排放的废汽加热热水供厂房采暖(冬季)和浴池(夏季)使用。至1981年初,换热器的受热面积已有50％以上因腐蚀而损坏,需更新或改造。 根据我们多年运行的实践,认为管束式换热器不适宜于回收锻锤废汽余热,其缺点是: Our workshop forging workshop discharges about 12 tons of waste steam per hour. Since 1963, we have adopted four tube-bundle heat exchangers (each with an area of ​​80m ~ 2, Heating (winter) and baths (summer). By the beginning of 1981, more than 50% of the heat exchanger area had been damaged due to corrosion and had to be renewed or retrofitted. According to our years of practice, the tube-bundle heat exchanger Suitable for recycling forging hammer waste heat, its drawback is:
