中小型企业事业团,为提高能源的利用率、有效地利用废热、及煤炭的转换等进行了节省能源,代替石油资源等的技术开发,研究提高中小企业使用的冲天炉的热效率,开发高效率的冲天炉。该开发为了提高冲天炉的熔化效率,以回收余热,来提高送风温度,进入热交换器的排气温度即使在700℃以下,也能得到400℃以上的送风温度。而且简化了热交换器的保养、管理,并能自动除去附在传热管表面的煤灰。
Small and medium-sized business groups have conducted technological development to save energy and use petroleum resources to improve the utilization of energy, effectively utilize waste heat and conversion of coal, and study the thermal efficiency of cupola used by small and medium-sized enterprises and develop high efficiency Cupola. In order to increase the melting efficiency of the cupola, the blast furnace was designed to increase the blowing temperature by collecting the waste heat. When the temperature of the exhaust gas entering the heat exchanger was lower than 700 ° C, the blowing temperature of 400 ° C or higher was obtained. But also simplifies the maintenance and management of the heat exchanger and automatically removes the soot attached to the surface of the heat transfer tube.
