全国工业锅炉的蒸汽管网的煤耗约占全国煤耗的三分之一,但热能利用率却很低,仅占29.7％,只有日本热能利用率的一半。每年要浪费标准煤3800万吨,折原煤5300万吨,相当于蒸汽管网全年能耗的四分之一,其中仅回收一项(包括阻止蒸汽泄漏和合理回收结水两部分就有1100万吨标煤的节约潜力,占蒸汽管网 The coal consumption of the steam pipe network of industrial boilers in the country accounts for about one-third of the national coal consumption, but the utilization rate of heat energy is very low, accounting for only 29.7%, and only half of Japan’s thermal energy utilization rate. Annually, 38 million tons of standard coal will be wasted, equivalent to 53 million tons of raw coal, equivalent to a quarter of the annual energy consumption of the steam pipeline network, of which only one will be recovered (including the prevention of steam leakage and the reasonable recovery of 10,000 tons of standard coal savings potential, accounting for steam pipe network
