摘要
针对某1 000 MW双切圆燃煤锅炉在高灰熔点煤与低灰熔点煤混烧过程中出现的结渣问题，开展了现场试验与数值模拟研究。试验研究表明：随着低灰熔点煤掺烧比例的增加，炉内结渣呈现明显加剧趋势；当低灰熔点煤掺烧比例为50%时，炉内出现轻微结渣；掺烧比例提升至67%时，大屏底部受热面出现大面积结焦；当掺烧比例达到83%时，结渣情况显著恶化，炉渣中渣块占比超过40%。结渣数值模拟结果表明：结渣主要集中在前墙和后墙区域；各受热面结渣程度随低灰熔点煤比例增加而加重；低灰熔点煤的掺入虽未显著改变近壁面温度，但混煤灰熔点大幅降低是结渣恶化的根本原因；低灰熔点煤在燃烧器中投运方式对结渣影响显著，其中D、C层掺烧低灰熔点煤时结渣趋势尤为明显；建议优先在A、B层布置低灰熔点煤，其次考虑F层，应避免在D、C层掺烧低灰熔点煤。结渣数值模拟与现场运行试验结果趋势吻合良好。
