摘要

某电厂 30 0MW机组锅炉因炉内严重结渣限制了锅炉出力。通过现场和实验室试验

查明了引起炉内结渣的主要原因

制定了燃烧器改造和综合治理方案。通过在一次风喷口中加导流板

减少气流的偏转

并用计算机数值模拟和冷模试验相结合的方法

确定一次风加导流板前后气流偏转和炉内流场的变化

用蒙特卡洛法计算了加导流板前后炉内温度场的变化。基于试验和计算结果

确定了导流板尺寸。改造方案实施后

解决了炉内结渣问题

Abstract

Serious slagging in the furnace of a 300MW boiler has restricted output capacity of the said boiler. Through field and laboratory tests

main reasions causing the slagging in furnace have been found

and a scheme of retrofitting the burners and comprehensive treatment has been worked out. Via adding guide-plate in the jets of primary air to reduce the deflection of gas flow

combined with methods of numerical simulation by using computer and cold model test

the variation of gas flow deflection and of flow field in the furnace before and after adding the guide-plate of primary air has been determined

and the variation of temperature field in the furnace before and after adding the said guide-plate has been calculated by using the Monte-Carlo method. Based on the results of test and calculation

the dimensions of the guide-plate are determined. After realization of the retrofitting scheme

the problem of slagging in the furnace has been solved.
