煤的结渣性是指煤在气化或燃烧过程中的灰渣受热是否会融熔而结疤以及结疤的强弱的性能。在气化炉或燃烧炉内,通常用煤灰熔点(T_2)较低的煤就较易结渣,影响气化过程的正常进行或者造成锅炉的清渣困难。 GB1572—79《煤的结渣性测定方法》自1980年实施以来十年,兹就个人工作中遇到的一些问题,提出一些看法。一、试样所需量太大,难以满足规定量的要求。
Slagging of coal refers to the performance of coal in the process of gasification or combustion of the ash will be melted and scarring and the strength of scarring. In gasifiers or furnaces, coal with a lower coal ash (T_2) is usually easier to slag, affecting the normal gasification process or causing boiler slag removal difficulties. GB1572-79 “Determination of slagging of coal” Ten years since its implementation in 1980, some personal problems encountered in the work, made some observations. First, the sample required too much, it is difficult to meet the required amount of requirements.
