生物质与高硫劣质煤混烧固硫特性研究

STUDY ON THE SULFUR FIXATION CHARACTERISTICS OF CO-COMBUSTION BIOMASS AND HIGH-SULFUR LOW QUALITY COAL

使用快速智能定硫仪对小麦秆、棉花秆、玉米秆三种生物质分别与高硫劣质煤混烧的固硫特性进行了研究,分析了不同混合比、温度及生物质灰成分等因素对固硫率的影响.实验结果表明,温度对固硫效果影响较大,总固硫率随温度的升高而下降;相同温度下生物质含量越高,固硫效果越好;生物质种类不同,固硫效果也不相同;生物质中氯与碱金属含量对固硫效果的影响较大.

The sulfur fixation characteristics of co-combustion wheat straw, cotton stalk, corn stalk and high sulfur low quality coal respectively were researched with quick intelligence sulfur analyzer. The influence of different mixing ratios, temperature and the composition of bio- mass ash to sulfur fixation ratio was analyzed. The results of experiment indicate that tempera ture make major impact on sulfur fixation ratio, the total sulfur fixation ratio decreases with tem- perature rising. In the same temperature, higher content of biomass makes better sulfur fixation effect. Sulfur fixation effect is different using different biomass. The contents of chlorine and al- kali metal in biomass make great impact on sulfur fixation effect.
