通过对不同环境下的锅炉进行实验分析,我们发现,烟气流速的变化、灰分的特性、灰粒的撞击方向、烟气的温度都会对锅炉受热面磨损产生影响。烟气的流动速度越快,灰分中间的颗粒物越不规则,灰粒的撞击方向越接近90°,烟气的温度越高,都会导致锅炉的受热面磨损程度越大。现阶段,我们需要对锅炉的燃烧方法和锅炉的运行方式进行调整,以保证燃煤的充分燃烧。与此同时,我们还要对已出现磨损的部位进行加厚或及时的检修等,以减轻锅炉受热面的磨损,保证锅炉的正常运作和有效利用。
Through the experimental analysis of boilers in different environments, we found that the variation of flue gas flow rate, the characteristics of ash, the impact direction of ash particles and the flue gas temperature all have an impact on the heating surface wear of the boiler. The faster the flue gas flow, the more irregular the particles in the middle of the ash, and the closer the collision direction of the ash particles is to 90 °, the higher the temperature of the flue gas will cause the heated surface of the boiler to wear more. At this stage, we need to adjust the method of boiler combustion and boiler operation, in order to ensure the full combustion of coal combustion. At the same time, we also have to wear parts of the thickened or timely maintenance, in order to reduce the heating surface of the boiler wear and tear to ensure the normal operation of the boiler and effective use.
