摘要

通过试验表明

因空气预热器阻力大

致使锅炉在过低氧量下运行。试验所用 4种煤的结渣性能为中等

不会引起严重结渣

炉内结渣的主要原因是氧量太低

出现还原性气氛所致。锅炉飞灰可燃物高主要是炉内空气过剩系数低及煤中混有难燃煤种所致

对此给出简易判别方法

Abstract

Test results show

the resistance in air preheater was larger

making the boiler to be operated under condition of over-low oxygen content.This is the main cause leading to slagging in furnace

making reductive atmosphere to be occurred.High content of unburned carbon in fly ash was the result of low percentage of excess air during combustion and the burned-coal blending with difficult burn-up coal sort.At last

a simple distinguishing method for this is given.
