我国农村普通的旧式柴灶与煤灶有两大缺点。一是灶膛大、灶门大,二是没有灶箅和一般不设通风道及烟囱。这就造成柴、煤燃料不能充分燃烧,热能不能充分被利用,并且由于通风不好,满屋呛烟很不卫生。因此改革炉灶,既是节省能源,缓和农村缺烧紧张局面的有力措施,能又改善卫生条件, There are two major shortcomings of common old firewood stoves and coal stoves in rural China. One is that the stove is large and the stove door is large, and the second is that there is no stove and there are no ventilation channels and chimneys. This results in the incomplete combustion of firewood and coal fuel, the inefficient use of thermal energy, and the unhygienic nature of the smoke from houses due to poor ventilation. Therefore, the reform of the stove is not only a power-saving measure, but also a powerful measure to ease the shortage of burning in rural areas, and it can also improve the health conditions.
