农村社员家用锅灶普遍的缺点是:灶门大、喉眼大、炉篦子大、灶堂大、锅底与炉篦子距离高、结构不合理、燃烧不完全、热效率低、浪费柴煤较严重。我们学习了外地“月牙形”节柴灶和“三小一深”节煤灶的优点,把旧式锅灶改成“三小弧形”节柴节煤灶。经过五十户实测,成功率达100％,节能效果明显:平均节柴 Common disadvantages of rural household cooktops are: big kitchen door, big laryngeal eye, large grate stove, big kitchen stove, high grate bottom and furnace grate, unreasonable structure, incomplete combustion, low thermal efficiency, waste of coal more serious .
