Microscopic constituents in solid residues from households combustion
|October 12, 2021||Filled under Com III||
Currently, numerous studies on the possible co-combustion of waste and biomass, based on the analysis of ash from household furnaces, are being carried out. These studies are based on physico-chemical analysis. Determining optically recognizable characteristic residues in ashes from unwanted additives burned with fuels will complete and simplify these analyzes. This will also allow the identification of components that were previously impossible or very difficult to detect.
Based on preliminary petrographic analysis of grill fuels and biomass (pellets, chips, cuttings, shredded wood), photographs of optically identified undesirable components, such as fossil coal, crude oil, coke, coal-pitch, plastics, glass, slag, rust, metals, stone powder (thermally unchanged mineral matter), in these products were taken. As a result of these analyzes, a catalog of the abovementioned impurities that can be determined in both thermally processed and unprocessed biomass (charcoal) was developed.
The purpose of the exercise is to optically identify the quality and quantity of components found in ashes obtained from household furnaces. Optical examination of ashes obtained from boilers and furnaces combined with their physical and chemical analysis will allow determining the quality of fuels used in domestic furnaces after their combustion. This will also allow identifying and eliminating contaminated fuels produced from biomass and used in household furnaces.
