我区1974年以后建成的500吨/日糖厂,大部份使用两台SZS10-25/400型10吨/时煤粉锅炉(原型号为SZF10-25/400),燃料以蔗渣为主煤为辅。这种锅炉在使用开始就存在不少问题,如蔗渣在炉排上成堆,底风不足,炉膛温度太低,造成燃烧不良,蒸汽供应不足,煤耗普遍偏高等。经过几年来的生产实践,各厂逐步摸索了改进这种锅炉燃烧的好办法.从 Most of the 500 tons / day sugar mills built in our district after 1974 are equipped with two SZS10-25 / 400 10 ton / hour pulverized coal boilers (formerly SZF10-25 / 400), with bagasse as the main fuel Supplemented. Such a boiler has many problems at the beginning of its use. For example, bagasse is piled up on the grate, the bottom wind is insufficient, the furnace temperature is too low, resulting in poor combustion, insufficient steam supply and generally high coal consumption. After several years of production practice, the factory gradually groping for a good way to improve the combustion of such a boiler.
