一 引言 七十年代以来,我国广大能源工作者认识到炉煤不相适应的主要矛盾是煤质变化过于频繁。因此,煤炭供应部门为了扭转不合理的单煤供应方式,开始实行优、劣质煤搭配供应,用户在炉前自行搅拌匀和成混合煤,供锅炉燃烧。但是,由于各种条件的限制,上述供煤方式很快为八十年代初的动力配煤供应所取代。 所谓动力配煤,是把二种或二种以上的原煤,按一定比例进行机械混合,使混合后的煤炭质量符合工业锅炉的燃烧需要。换言之,即根据锅炉的燃烧条件,结合当地煤炭资源的特点,用科学方法配制出适应不同炉型类别要求的系列动力配煤。因此,后者既能较充分地利 I. INTRODUCTION Since the 1970s, the majority of energy workers in our country have realized that the main contradiction between the misfiring of coal and coal is that coal quality changes too frequently. Therefore, in order to reverse the unreasonable supply of coal, the coal supply department started to implement the supply of superior and inferior coal, and the users themselves mix and mix the coal uniformly in the front of the furnace for boiler combustion. However, due to various conditions, the above coal supply was quickly replaced by the power supply of coal blending in the early 1980s. The so-called dynamic coal blending is the two or more than two kinds of raw coal, according to a certain percentage of mechanical mixing, so that the quality of the coal after mixing with the industrial boiler combustion needs. In other words, according to the combustion conditions of the boiler, combined with the characteristics of the local coal resources, the scientific method is used to prepare a series of dynamic coal blending to meet the requirements of different types of furnaces. Therefore, the latter can be more fully utilized
