水文测量队“中游”轮大车丁天喜同志,在“中游”轮大修中,由於自己积极想办法、找窍门,提出了在烟囱内安一活动盖,以节约燃料的建议,经试验证明,每推压火一次。可节约用煤一百市斤左右。试验的经过是这样:第一次推压火时,不用活动盖,计压火用煤一八○市斤,半夜加煤一次(因该轮锅炉未包石棉怩,半夜需加煤一次),用煤五○市斤,推火用煤二七○市斤(泗汀一二○磅),推压火一次,共计用煤五○○市斤。第二次推压火时,将活动盖关闭,压火用煤一八○市斤、夜晚未加煤,推火用煤二二○市斤(泗汀一二○磅),推压火一次,共计用煤四○○市斤,与第一次不用活动盖相比较,整整节省煤一○○市斤。
Comrade Ding Tianxi of the “middle-travel” wheel cart of the hydrological measuring team, in the “Medium of the Central” round of overhaul, because of his active efforts to find ways to find tips, put forward an activity cover in the chimney to save fuel, and the test proved that each Push the fire once. It can save about 100 kilograms of coal. After the first test, the first time the fire was pushed, without using a movable cover, the coal for pressure fire was 180 tons, and coal was added at one time in the middle of the night (because the asbestos boiler was not included in the round of boilers, coal was added in the middle of the night). The use of coal for 50 tons, pushing fire with 270 tons of coal (Jin Ting-120 pounds), pushing the fire once, for a total of 500 tons of coal. When the fire was pushed for the second time, the movable cover was closed, the coal used for pressure fire was 180 tons, and coal was not added at night. The coal used for pushing out the fire was 200 tons (120-200 tons), pushing the fire once. A total of 400 kilograms of coal is used. Compared with the first non-active covers, the total coal savings are 100 kilograms.
