唐山工程技术学院煤化工教研室研制的TGM—R3型饮水锅炉,于1988年11月19日通过省级技术鉴定。该锅炉燃用烟煤型煤,可封火过夜。具有供饮用水、供汽蒸饭与加热浴室用水三种使用功能。其排烟黑度近于林格曼0级;排烟含尘浓度13毫克/标米~3。炉体结构设计中,采取多项技术措施,提高传热速率。总热效率为66.9％。比较原煤散烧的直立火管式饮水锅炉节约标准煤35％。按每小时供出1公斤开水计,钢材消耗量仅为国内已有卧式型煤茶炉钢材耗量的40％。按照TGM—R3型锅炉设计图样,对现有污染严重、能耗高的旧式直立火管锅炉,花费90余公斤钢材,就地即可完成改装。较
Tangshan Institute of Technology coal chemical research and development department developed TGM-R3-type drinking water boiler, on November 19, 1988 passed the provincial-level technical appraisal. The boiler burning bituminous coal, can be sealed fire overnight. With drinking water for steaming rice and heating the bathroom water three kinds of functions. Its smoke blackness nearly Ringelmann 0; smoke dust concentration 13 mg / m ~ 3. Furnace body structure design, to take a number of technical measures to improve heat transfer rate. The total thermal efficiency is 66.9%. Comparison of raw coal scattered vertical tube fire boiler saving 35% of standard coal. According to the hourly supply of 1 kg of water meter, steel consumption is only 40% of the domestic horizontal coal-fired stove steel consumption. In accordance with the design of the TGM-R3-type boiler, the existing upright, vertical tube-fired boiler with serious pollution and high energy consumption cost more than 90 kg of steel and could be converted on site.
