应西德巴高克集团和西德供热协会的邀请,于1985年1月11～26日对联邦德国进行了为期两周的高温热水系统节能技术考察。考察中,参观了设备(锅炉、汽轮机、热交换器热水器、泵调节阀钢制暖气片等)制造厂四家,热电站六个(其中有燃煤锅炉三个),程远供热公司六个,能源设备公司一个,供热协会一个,大型交换(输入和输出)站两个,入口装置四个,中心控制站一个。遗憾的是工厂余热利用仅远远看了一眼带钢轧制厂加热炉排烟出口管上的大型热交换器。参观计划都摹本上完成了,只是时间紧,了解深度不够。集中供热在我国的历史较短。“一五”期间.仅在部分大城市和工业区建设了一批区域性供热电厂,但多年来发展缓慢。为节约能源,六十年代中
At the invitation of the West German Bargok Group and the West German Heating Association, a two-week high-temperature hot water system energy saving technology inspection was conducted on the Federal Republic of Germany from January 11 to 26, 1985. During the inspection, he visited four manufacturers of equipment (boilers, steam turbines, heat exchangers, water heaters, and steel valves for pump regulating valves, etc.), six thermal power plants (including three coal-fired boilers), and six Chengyuan heating companies. One, an energy equipment company, a heating association, two large exchange (input and output) stations, four inlet units, and one central control station. Unfortunately, the use of waste heat in the factory has only looked very far at the large heat exchangers on the exhaust outlet pipe of the heating furnace in the strip mill. The visit plan was completed in a transcript, but the time was tight and the depth of understanding was not enough. The history of central heating in our country is relatively short. During the “1st Five-Year” period, a number of regional heating power plants were built only in some large cities and industrial areas, but they have been developing slowly over the years. To save energy, the mid sixties
