宁国县林化厂从1958年建厂起,都是采用滴水法直接火加工松香。十三年来一直用木柴作燃料。每年生产松香500吨左右,需木柴72万多斤,折合木材约450立方米。用木柴作燃料耗用工时长,温度高低不易掌握,产品质量不稳定,成本高,劳动强度大,炉前温高,影响工人身体健康。宁国县林化厂广大职工,遵照毛主席“自力更生”、“艰苦奋斗”的教导,大革“柴老虎”灶的命。经过一年的反复试验,成功地将 Ningguo Forest Plant from 1958 to build factories, are using drip method of direct fire-processing rosin. Thirteen years have been using firewood as fuel. About 500 tons of rosin is produced every year, 720,000 kilos of firewood are required, equivalent to about 450 cubic meters of wood. Fuel consumption with firewood for long working hours, the temperature is not easy to grasp the level, product quality is unstable, high cost, labor intensity, high temperature before the furnace, affecting the health of workers. Ningguo County Forest Plant majority of workers, in accordance with Chairman Mao “self-reliance” and “hard work” teaching, leather “firewood tiger” stove life. After a year of trial and error, successfully will
