Experimental Studies on the Gasification Potential of Sawdust and High-Ash Indian Coal Blends in a Fluidized Bed Gasifier

The fluidization of solids with the use of particle suspension in fluid media is essential to achieving a constant bed temperature and a quick rate of heat transmission. Indian high-ash coal and sawdust were selected as the study's biomass materials while keeping in mind the Indian setting. Coal and sawdust work synergistically to enhance the process and its yield when mixed and gasified. Coal was pulverized or grinded to the specific size range needed for suspension in a fluid condition. Samples of sawdust were combined in weight ratios of 10, 20, and 40% with coal. The gasification process was successfully finished at temperatures between 850 and 960 °C without encountering any operational issues. The carbon conversion efficiency (CCE), calorific value of the product gas (CV), cold gas efficiency (CGE), and syngas production per kilogram of feed were evaluated for each scenario of the mix. It was demonstrated that the output of syngas per kilogram of feed increases for all biomass blends as the gasification temperature rises from 850 to 960 °C. Additionally, it was discovered that as reactor temperature and mixed biomass content increase, so do the concentrations of CCE, CV, CGE, and CO-H2 in the product gas.
