摘要

通过运行优化

能够使循环流化床(CFB)锅炉燃用低挥发分贫煤和无烟煤的飞灰含碳量控制在10%以内。分析了贫煤循环流化床锅炉燃料粒径分布

床压和一、二次风率对飞灰含碳量的影响。在燃用低挥发分贫煤和无烟煤时

控制入炉煤中小于100μm的颗粒所占比例

采用较低的床压和增加二次风的混合可降低飞灰含碳量。

Abstract

The factors impacting carbon content in fly ash of the CFB boiler burning low volatile bean coal and anthracite

such as distribution of coal granules fed

bed pressure

primary secondary air fractions

are analyzed.It is found that controlling the fraction of the particles under 100 μm in feeding coal

lowering the bed pressure

and enhancing secondary air blending can all help to decrease the carbon content in fly ash of the CFB boiler burning low volatile lean coal and anthracite.By operational optimization

the carbon content in fly ash of this CFB boiler can be controlled below 10%.
