  • 摘要: 选取CaCO3、Ca(OH)2质量配比＝3∶2作为主固硫剂，用钙基固硫剂质量的2％的Na2CO3对其改性，利用蛭石作为固硫添加剂。在Ca/S＝2.25的情况下,通过固硫实验考察了主固硫剂以及添加剂的加入对固硫率的影响。实验结果表明，煤粉掺入该固硫剂在950℃下燃烧0.5 h，固硫率可以达到85％。还对添加不同固硫剂的煤粉进行热重实验，分析其对煤粉燃烧特性及动力学参数的影响。结果表明，固硫添加剂的加入不但能提高固硫率，还有利于煤的燃烧，减少灰渣的处理量。
    Abstract: Ca(OH)2 and CaCO3 were selected as the main sulfur-fixed agent, their mass ratio is 2∶3. Vermiculite and Na2CO3 were selected as the additives. The influence on the desulphurization ratio by the addition of main sulfur-fixed agent and additives were studied under Ca/S=2.25. Result shows that the desulphurization ratio of powder coal with the addition of sulfur-fixed agent can achieve 85% at 950℃ and burning half an hour. TG experiment was carried on the coal with different sulfur-fixed agents, their effects on the coal combustion characteristic and kinetic parameters were analyzed. Conclusion draws that the addition of main sulfur-fixed agent and additives not only enhanced the desulphurization ratio, but also promoted coal combustion and reduced the amount of coal ash.
