中小学校的采暖系统,尤其是放寒假期间最容易冻坏,又浪费煤,为解决此问题,研制了小型节能热风炉,不需要水箱、循环水泵、暖气和水处理设备等。初投资和土建投资可节省30%左右,可随时停烧,可节煤40%左右,还可节省大量的电费和维护费等。主要技术指标:(1)、采暖面积60～600m~2的学校,一冬耗煤近70吨,热效率达60%左右,无压力,按节煤40%计算,节煤达30吨,如推广此种采暖方式,
The heating systems of primary and secondary schools, especially during cold holidays, are the most prone to freezing and waste of coal. In order to solve this problem, small-scale energy-saving hot-air stoves have been developed without the need for water tanks, circulating water pumps, heating and water treatment equipment. The initial investment and civil construction investment can save about 30%, can be stopped at any time, can save about 40% of coal, but also save a lot of electricity and maintenance fees. Main technical indicators: (1) Schools with heating area of 60 to 600m~2, coal consumption of nearly 70 tons in winter, thermal efficiency of about 60%, no pressure, 40% of coal savings, 30 tons of coal savings, such as promotion This heating method,
