目前我国居民生活用煤,由于燃烧设备落后,热利用率平均只有20%左右,不仅浪费了能源,而且污染环境. 为了抓好节煤工作,1988年底,我县农村能源办公室成立了炉具研制小组,本着节能、实用的原则,精心设计,反复试验,研制成功了“XL D型高效节能多用炉”. At present, China’s residents living coal, due to the backward combustion equipment, heat utilization average only about 20%, not only a waste of energy, but also pollute the environment.In order to do a good job of coal-saving work, by the end of 1988, I County Rural Energy Office set up a stove developed Group, in the energy-saving, practical principles, well-designed, trial and error, the successful development of the “XL D-type energy-efficient multi-purpose furnace.”
