在工业锅炉中,链条炉是普遍采用的一种燃饶设备。但其实际效率很低,与大型煤粉炉相比,差距很大。为充分利用原设备,将链条炉改成以燃煤粉为主的链条炉,既能提高效率,又能增加出力。与改前相比,锅炉效率从60％提高到80％,实际出力也有大幅度提高,例如Д20型锅炉从16t/h增加到23t/h,321-20-39型锅炉从16t/h增加到30t/h。蒸汽品质、消烟除尘均符合国家要求。与改前相比,每台锅炉年节煤4800吨,节约运行费用9万多元。收回全部投资费用不到一年的时间。
In industrial boilers, chain furnace is commonly used as a kind of burning equipment. But its actual efficiency is very low, compared with the large-scale pulverized coal stove, the difference is very big. To make full use of the original equipment, the chain furnace into a coal-based chain furnace, both to improve efficiency, but also increase the output. Compared with the pre-reform, boiler efficiency increased from 60% to 80%, the actual output has also been greatly improved, for example, the Д20 boiler increased from 16t / h to 23t / h, 321-20-39 boiler increased from 16t / h 30t / h. Steam quality, smoke and dust are in line with national requirements. Compared with the pre-reform, the annual coal-saving 4,800 tons of each boiler, saving operating costs more than 90,000 yuan. Less than a year to recover the entire investment costs.
