循环流化床燃烧室内煤自脱硫效率的试验研究

摘要

就5种煤在1MWth循环流化床燃烧室中的自脱硫性能进行了试验研究和分析。试验结果发现，随着温度的增加，煤的自脱硫效率降低。不同煤的自脱硫效率有较大的差别，煤的自脱硫对石灰石脱硫效率的评价有较大影响。%The experiment study and analysis of coal self-desulfurization property by using 5 kind coals in 1 MWth CFB chamber are conducted. Experiment result is shown that, the coal self-desulfurization efficiency decreased along with the temperature increasing. Coal self-desulfurization efficiency possess bigger different when using different coals. It has a bigger influence on the evaluation of limestone desulfurization efficiency.
