近几年来,我国各锅炉制造厂所生产的余热锅炉安装使用后,每年大约回收300万吨标准煤的热能,其它行业的制造厂以及用户自行制造和引进设备的余热回收量约为每年230万吨标准煤。 根据国家计委和中国科学院的粗略统计,我国每年可回收利用的余热资源大约相当于2000万吨标准煤。随着工业的发展,可供回收利用的余热资源还会不断增加。可见
In recent years, after the installation and use of waste heat boilers produced by various boiler factories in our country, approximately 3 million tons of standard coal heat are recovered annually, while the recovery of waste heat recovered by manufacturers in other industries and by users for their own manufacture and introduction of equipment is about 2.3 million Tons of standard coal. According to the rough statistics of the State Development Planning Commission and the Chinese Academy of Sciences, the annual waste heat resource that can be recycled in China is equivalent to about 20 million tons of standard coal. As industry develops, the amount of waste heat available for recycling will continue to increase. visible
