配煤对锅炉燃烧、除尘和脱硫性能的影响

Effect of blended coals on combustion, desulfurization and dust collection

针对我国电厂用煤的现状,在综合考虑锅炉燃烧和烟气除尘、脱硫的基础上,通过建立数学模型,推导出基于煤质指标计算锅炉效率、除尘效率、脱硫率的公式,并分析研究了3煤种配煤对锅炉燃烧和除尘、脱硫性能的影响,可为电厂优化配煤方案提供参考依据。

Combing combustion in boiler and the request to reduce SO 2 and dust emission, the mathematic models were made and calculation formulas which related to coal quality index were found out. The effect on combustion, desulfurization and dust collection with blended coals by three kinds of coals was studied.
