炉灶是家家少不了,天天都要用的。但当前广大农村家家户户使用的炉灶,多是传统的旧灶,结构不合理——灶堂空间大、添柴加煤的灶门大、灶膛底下无篦子、有的甚至连个烟囱也没有,因而散热多、费柴、费煤(烧十斤柴,只有一斤多被利用上了),烧饭也费时间,烟熏火燎,很不卫生。如何把这种旧灶改为新灶,使之结构合理,达到省柴省煤、省时间,使用方便、安全卫生呢?这就要搭砌省柴灶。现在,全国很多地方创造出了适宜当地需要的省柴灶,很受欢迎。它们使烧柴的有效利用率提高了近两倍。就是说,原来用旧灶,烧一顿饭的柴,现在换用新灶,可以烧两顿饭了。原来一年缺3～4个月烧柴的,可以够烧而不缺柴了。这是多么大的成绩啊!省柴灶省柴、好使,关键是它的结构合理。克服了旧灶的“两大两无”弊 Stoves are indispensable to our daily life. However, at present, most stoves used by every household in rural areas are mostly traditional stoves, and the structure is irrational. There is a large space in the stove hall, large stove doors with coal and coal, no grate under the hearth, and some do not even have a chimney. Cooling more, Fei Chai, Fei coal (burning ten pounds of firewood, only a pound more to be used), cooking also takes time, smoky, very unhygienic. How to put this old stove into a new stove, so that the structure is reasonable, to provincial firewood save coal, save time, easy to use, safety and health it? Nowadays, firewood stoves suitable for local needs have been very popular in many parts of the country. They have nearly doubled the effective use of firewood. In other words, the original use of old stove, burning a meal of wood, now for the new stove, you can burn two meals. The original lack of 3 to 4 months a year firewood, can burn without missing a firewood. This is a big achievement ah! Provincial firewood save firewood, so that the key is its reasonable structure. Overcome the old stove “two big two no” disadvantages
