据国内有关专家鉴定,长沙、衡阳锅炉厂生产的两种锅炉,是目前燃用中次烟煤最好的锅炉。长沙锅炉厂生产的KZL4——13——AⅡ锅炉,是1984年试制成功,3月试烧,10月测试鉴定投产的。该炉使用3000——4200千卡/公斤烟煤,小时蒸发量4024-4568公斤汽。燃用3800千卡/公斤Ⅱ类烟煤时,热效率达79.3％(超过国家规定指标10.3％)。每台每年可节煤320吨。衡阳锅炉厂试制成功WWW1——7AⅡ燃用劣质煤锅炉。1984年8月鉴定投产。用中次烟煤,热效率为78.3％(超过国家标准18.3％)每年可节煤300吨。该炉还可燃用
According to the domestic experts appraisal, Changsha, Hengyang boiler plant production of two kinds of boilers, is currently burning the best sub-bituminous coal boiler. KZL4--13 - A Ⅱ boiler produced by Changsha Boiler Factory was successfully trial-produced in 1984, tested in March and burned in October. The test was put into operation in October. The furnace using 3000 - 4200 kcal / kg bituminous coal, hourly evaporation 4024-4568 kg gas. Burning with 3800 kcal / kg Ⅱ class bituminous coal, the thermal efficiency of 79.3% (10.3% more than the national target). Each can save 320 tons of coal each year. Hengyang boiler plant trial successful WWW1 - 7A Ⅱ combustion of low-quality coal boiler. August 1984 appraisal put into operation. With the second bituminous coal, thermal efficiency of 78.3% (more than the national standard 18.3%) can save 300 tons of coal each year. The stove is also combustible
