摘要

重新设计的原料技术在以煤为主要燃料的全规模 AFBC 锅炉上使用物理处理将劣质煤转化为优质煤。由于物理原料混合被认为具有改善煤炭燃烧的质量、环境影响和能源效率的潜力,因此对其进行了调整。添加 6.3% 的石灰石后,二氧化硫排放量大幅减少了 34%,保留的铁则确保了结构的稳定性。侵蚀腐蚀性研究确保了结构材料不会因石灰石颗粒的引入而退化。烟气中硫含量浓度的降低和石灰石对表面的钝化共同作用,减少了对来福枪管段的侵蚀-腐蚀效应。

Effect of Limestone Addition to Coal on SO2 Emission Control and Erosion-Corrosion Behaviour of Rifle Bore Bed Tube in AFBC Boiler

Effect of Limestone Addition to Coal on SO2 Emission Control and Erosion-Corrosion Behaviour of Rifle Bore Bed Tube in AFBC Boiler

The re-engineered feedstock technique converts low-quality coal into high-quality coal using physical processing on AFBC boiler under full scale with coal as primary fuel. The physical feedstock mixing was adapted as it is identified as having the potential to improve the quality, environmental impact, and energy efficiency of coal combustion. The addition of 6.3% of limestone significantly reduced the SO2 emissions by 34% and the structural stability was ensured by the retained Fe. The erosive corrosive studies ensures no degradation to the structural material due to the introduction of the limestone particulates. The reduced concentration of sulphur content in the flue gas and passivation of surfaces with the limestone together synergetically reduced the erosion-corrosion effect on the rifle tube section.

期刊介绍: The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
