摘　　要：在７５ｔ／ｈ锅炉上对煤种的适应性进行实验，结果表明，循环流化床锅炉对煤种的适应性是有限的，燃用低灰分高热值燃料将导致灰平衡被破坏，燃烧、传热和流动均受到影响．合理添加河砂或石灰石类床料可以调整到理想工况。Several kinds of coals are used in a 75t/h CFB boiler to investigate the fuel flexibility and the relation of fuel with material balance. The results indicate that the fuel flexibility is under some condition, especially for low ash content,high heat value coal, the boiler performance can't be achieved as design value because the material balance is broken. The boiler would be adjusted well by adding some matter such as sand or limestone.

关 键 词：循环流化床锅炉 燃料 灰平衡
