杭州味精厂一台六吨半锅炉,经过改进,使单位产品煤耗不断下降。去年,增设沉降室,烟囱基本不冒黑烟。在此情况下,节煤是否还有潜力可挖?推广优选法以来,有的认为0.618是数学上的数字,算不来,用不上。有的认为锅炉是个庞然大物,可变因素多,情况复杂。试验时万一出力降低,影响生产,怎么办?该厂司炉工人听了华罗庚同志报告后,思想开了窍,他们说:“大庆工人补皮鞋也搞优选法,我们为什么不能在锅炉节煤上试一试优选法?”他们“重实践,抓矛盾”,首先分析了当前节煤的主要矛盾是,锅炉的抛煤机把少 Hangzhou MSG plant a six-ton ​​boiler, improved to make the unit of coal consumption continued to decline. Last year, an additional sedimentation chamber, the basic non-smoky smokestacks. Under such circumstances, there is still potential for saving coal? Since the promotion of the preferred law, some people think that 0.618 is a mathematical figure, do not come, do not have access. Some believe that the boiler is a monster, many variables, the situation is complicated. After the trial, the laborer listened to the report of Comrade Hua Loo-keng and thought was opened. They said: “Daqing workers make up shoes also have a law of preference. Why can not we try on the boiler coal saving? A try preferred method? ”They“ practice, grasp the contradiction, ”first analyzed the main contradiction between the current coal is that the boiler throw coal less
