为了实现锻造煤气加热炉的节能降耗,根据煤气加热炉的加热原理,结合工厂实际生产状况,对加热炉结构及供热方式进行了改造。采取缩小炉膛底面积,增加煤气回拢性,提高煤气利用率;在炉体外型尺寸不变的情况下,通过减小炉膛面积,使炉体内腔壁加厚,并在炉膛内布置若干块Φ120mm×240mm空心蓄能砖,增加高保温效果,提高炉膛使用寿命;重新配置进气结构,减少煤气进气量,由原来的4个烧嘴改为2个烧嘴,对煤气供气口进行合理配置,降低了煤气炉的能耗,全年可节省煤气费用60余万元。由于加热炉采用了均匀加热温度方式,提高了锻件加热质量,大大降低了产品废品率,为实现锻造用加热炉的改造和节能降耗提供了有效的实践依据。
In order to achieve the energy saving of the forging gas heating furnace, according to the heating principle of the gas heating furnace, combined with the actual production status of the factory, the heating furnace structure and heating mode were modified. Adopting the method of narrowing the bottom area of the furnace, increasing the return of the gas and increasing the utilization rate of the gas; by reducing the area of the furnace body, the inner cavity wall of the furnace is thickened and a number of Φ120mm × 240mm hollow storage brick, increase the effect of high thermal insulation, improve the life of the furnace; re-configure the intake structure, reduce gas intake, from the original four burner to two burners, the gas supply port reasonable Configuration, reducing the energy consumption of gas stoves throughout the year can save gas costs more than 60 million. As the heating furnace using a uniform heating temperature, improve the quality of forgings heating, greatly reducing product rejection rate, for the realization of forging furnace transformation and energy saving provides an effective basis for practice.
