Abstract
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.
