浙江肖山砖瓦厂通过狠抓思想教育和采取了一系列的有效措施,在节约煤炭方面取得了很大的成绩。今年上半年,该厂每千块砖平均标准煤耗为70.30公斤,比去年的87.42公斤降低了19.58%。他们在节约煤炭方面采取的主要技术措施是: 一、掺加5%的煤渣作瘦化剂,使干燥效率提高18%,干燥周期缩短4.3天。不掺煤渣的砖每千块煤耗为84公斤,掺煤渣的砖每千块为61公斤。砖的强度也由140.5公斤/平方厘米提高到272公斤/平方厘米。二、改造輪窑结构,改进烧码技术。该厂的34门輪窑,原来宽和高均为3.3米,烟囱高45.29米,烟囱底内径为2.3米,上口内径0.74 Zhejiang Xiaoshan brick and tile factory has made great achievements in saving coal by paying close attention to ideological education and adopting a series of effective measures. In the first half of this year, the average standard coal consumption per 1,000 bricks in the plant was 70.30 kg, which was 19.58% lower than last year’s 87.42 kg. Their main technical measures for saving coal are as follows: 1. Add 5% of coal residue as a lean agent to increase the drying efficiency by 18% and shorten the drying cycle by 4.3 days. The coal consumption per kilogram of bricks without cinder is 84 kilograms, and the kilogram of bricks with coal cinder is 61 kilograms per kilogram. The strength of the bricks also increased from 140.5 kg/cm2 to 272 kg/cm2. Second, reform the structure of the kiln and improve the code burning technology. The factory’s 34-door wheel kiln, the original width and height are 3.3 meters, 45.29 meters high chimney, chimney bottom diameter of 2.3 meters, the upper diameter of 0.74
