| 中文摘要: |
| 在研制新型菊芋秸秆-烟煤混合固体燃料的基础上，筛选不同添加剂[MgCO3、CaCO3、Al2O3、Al2Si2O5（OH）5]优化燃料，以提高生物质混合固体燃料的燃烧性能。将四种添加剂以3%比例（质量比）与菊芋秸秆-烟煤混合固体燃料混合，比较了不同添加剂对混合固体燃料的灰分、结渣率、放热量、烟黑、灰熔点、烟气成分等的影响。结果表明：四种添加剂对酸性气体有明显的吸附作用，且能有效降低混合固体燃料的结渣率，其中CaCO3添加剂使混合固体燃料的灰分含量、烟黑的林格曼指数下降最为明显。这表明，CaCO3添加剂能有效缓解混合固体燃料中的灰分、烟黑、酸性气体的生成，提高其燃烧性能，是一种较为理想的新型菊芋秸秆-烟煤混合固体燃料添加剂。 |
| 英文摘要: |
| Jerusalem artichoke biomass has been used to produce biofuel and can also improve the combustion performance of bituminous coal after adding to the coal. However, Jerusalem artichoke-bituminous coal solid biofuel pellets(JAC pellets) still produce large amount of slag during combustion. Here we examined the combustion characteristics of JAC pellets after mixing with MgCO3, CaCO3, Al2O3 and Al2Si2O5(OH)5 at 3%(m:m) to select additives for optimum combustion performance of JAC pellets. Results showed that adding additives decreased slagging rates to a great extent, while absorbed acid gases effectively. Addition of CaCO3 resulted in a significant reduction in ash content and Ringelman emittance. In summary, CaCO3 improved the combustion performance of the JAC pellets and could be a promising additive for JAC pellets. |
