一、概述清华大学高温热水锅炉房于1979年底开始设计,经过设计、施工单位和学校三方面的共同努力,克服了各种困难,已于1981年冬天建成投运供热。该锅炉房自运行以来,前去参观和了解情况的单位很多,也引起了有关方面的注意和重视。为了推动集中热水采暖工作的开展,我们将清华大学高温热水锅炉房的设计和运行情况作一简要的介绍。根据清华大学提出的设计任务书要求,该锅炉房将供给约350000m~2的科研、生产建筑及家属区住宅采暖。按采暖耗热指标75kcal/m~2·h计算,锅炉房需要供热量为3150×10~4kcal/h(热损失系数为1.2)。由锅炉房送出130～80℃的高温热水,在供热区经过热交换站交换出95～70℃的低温水供用户使用(见图1)。根据上述热负荷要求,选用了
I. Overview Tsinghua University’s high-temperature hot-water boiler room was designed at the end of 1979. Through the joint efforts of the design, construction units, and the school, it overcomes various difficulties and was completed and put into operation in the winter of 1981. Since the operation of the boiler house, many units have gone to visit and understand the situation, which has also attracted the attention and attention of relevant parties. In order to promote the development of centralized hot water heating, we will briefly introduce the design and operation of the high-temperature hot water boiler room at Tsinghua University. According to the requirements of the design mission book proposed by Tsinghua University, the boiler room will supply about 350,000 m2 of scientific research, production of buildings and residential residential heating. Calculated according to heating consumption index of 75kcal/m~2h, the boiler room needs to supply 3150*10~4kcal/h (heat loss coefficient is 1.2). From the boiler room, high-temperature hot water of 130-80°C is sent out, and in the heating area, low-temperature water of 95-70°C is exchanged through the heat exchange station for users to use (see Figure 1). According to the above heat load requirements, selected
