摘要

新疆地区高碱煤结渣、沾污性极强，严重危害锅炉的安全稳定运行，直接制约地区火电企业的高质量发展。本文从实际应用角度剖析了高碱煤结渣沾污的形成、发展和危害过程，提出了从燃料、燃烧、吹灰等多方面协同优化来确保锅炉安全高比例燃用高碱煤的措施以及治理现役锅炉结渣沾污的一般化流程。采用该技术路径，预期350 MW和660 MW等级机组锅炉均可实现长周期安全高比例燃用高碱煤。

Abstract

The extremely strong slagging and ash deposition characteristics of high alkali coal in Xinjiang seriously endanger the safe and stable operation of boilers and directly restrict the high-quality development of regional thermal power enterprises. The formation and development process of slagging and ash deposition as well as the adverse effects were analyzed from the perspective of practical application. The general measures for slagging prevention and ash deposition control in existing boilers burning high-alkali coal with high proportions were proposed. The collaborative optimization of fuel blending

combustion organization

soot blowing process and other aspects is emphasized in these measures. The general workflow of controlling slagging and ash deposition was also proposed. Taking this technical path

it is expected that boilers of 350 MW and 660 MW units can burning high alkali coal with long-term safety and high proportions.
