SG—特大型高效节煤炉,是在87SG—工型炉基础上改制成的。烟尘浓度和烟气黑度均符合国家排放标准,热效率为47％以上,节煤率50％以上。1987年经过100多家初制茶厂应用结果,每公斤茶叶耗煤定额由原来0.9公斤至1公斤,下降到0.6公斤至0.7公斤,实际每公斤茶叶节约用煤半公斤左右。每安装一台节煤炉,年节约用煤3～5吨,当年收回投资有余。一、设计性能热负荷为7.5万千卡/小时,适用于制茶杀青、二青、烘干、蒸煮、消毒等生产用500人以上大灶。出厂价每台230元,改装费每台 SG-large-scale high-efficiency coal-saving stove, is based on the 87SG-type furnace converted into. Smoke concentration and flue gas blackness are in line with national emission standards, the thermal efficiency of 47% or more, coal-saving rate of 50% or more. In 1987, after more than 100 fresh-made tea factory application results, the consumption of coal per kilogram of tea from the original 0.9 kg to 1 kg, down to 0.6 kg to 0.7 kg, the actual saving of about half kilograms of coal per kilogram of tea. Each installation of a coal-saving stove, the annual savings of 3 to 5 tons of coal, then recover more than investment. First, the design performance Heat load of 75,000 kcal / hour, for green tea, two green, drying, cooking, disinfection and other production with more than 500 large kitchen. Ex-factory price of 230 yuan each, modification fee for each
