热力管道保温,主要是指输送热水、蒸汽的管道保温工程。辽宁省是全国耗能的大户,热力管道数不胜数,所以减少热力管道散热损失、提高热效率、节约保温投资潜力很大。仅以抚顺某厂一条φ100—φ500毫米、压力为10公斤/厘米~2、长25000米管线为例,由于保温工程质量欠佳,管理不善,全部热损失每小时竟达23×10~6千卡,相当于10公斤/厘米~2、300℃新蒸汽32.1吨/时的热量。该厂每年用于管道的维修费就高达200万元。因此,加强热力管
Thermal insulation of pipelines mainly refers to the pipeline insulation projects that deliver hot water and steam. Liaoning Province is a large country with large energy consumption and there are numerous heat pipes. Therefore, there is great potential for reducing heat loss from thermal pipelines, increasing thermal efficiency, and saving thermal insulation investment. In Fushun alone, a pipe with φ100-φ500 mm, pressure of 10 kg/cm2, and length of 25,000 meters was used as an example. Due to poor quality of insulation works and poor management, the total heat loss reached 23×10 to 6,000 per hour. The card, which is equivalent to 10 kg/cm~2, fresh steam of 32.1 tons/hour at 300°C. The annual maintenance cost for the pipeline is as high as 2 million yuan. Therefore, strengthening the heat pipe
