北票县位于辽宁西部,农村生活燃料不仅严重短缺,而且浪费现象严重。农户旧用锅灶普遍的缺点是:灶门大、喉眼(出烟口)大、炉篦子大、灶膛大,锅底与炉蓖子距离高。结构不合理,燃烧不完全,热效率10％左右。1981年我们学习了河南镇平“月牙型”节柴灶的优点,结合北方炕灶相连、柴煤混合、助风燃烧的实际情况,把旧式锅灶改成“三小弧形”节柴节煤两用灶。
Beipiao County is located in western Liaoning. Rural life fuel is not only a serious shortage, but also a serious waste. Households common disadvantage of old pots are: large kitchen door, laryngeal eye (smoke mouth) large furnace grate large, stove chamber, the bottom of the pot and the furnace grate high. Irrational structure, incomplete combustion, thermal efficiency of about 10%. In 1981, we learned the advantages of the “crescent-shaped” firewood stove in Henan Zhenping. Combining the actual situation that the north kang stove is connected and the coal-fired mixture and the combustion air are burning, the old-style stove was changed into “three small arcs” Coal dual-use stove.
