Quality assessment of gas produced from different types of biomass pellets in gasification process

Abstract

Gas from the gasification of pellets made from renewable sources of energy or from lower-quality fuels often contains a number of pollutants. This may cause technical difficulties during the gas use in internal combustion gas engines used for energy and heat cogeneration. Therefore, an adequate system of gas cleaning must be selected. In line with such requirements, this paper focuses on the characterization and comparison of gases produced from different types of biomass during gasification. The biomass tested was wood, straw, and hay pellets. The paper gives a detailed description and evaluation of the measurements from a fix-bed gasifier for the properties of the produced gases, raw fuels, tar composition, and its particle content before and after the cleaning process. The results of elemental composition, net calorific value, moisture, and ash content show that the cleaned gases are suitable for internal combustion engine-based cogeneration systems, but unsuitable for gas turbines, where a different cleaning technology would be needed.

The energy assessment of COVID-19 medical waste as a potential fuel

“…The elemental composition of pure spruce wood has been also observed in a study of Mikeska et al. with the following similar results: (a) 47.46% of C content, (b) 5.65% of H content, (c) 0.09% of N content, (d) 39.12% of oxygen content ( Mikeska et al, 2020 ). Compared to pure spruce sawdust, pellets have a slightly higher content of C, H, and N. Based on these results, it can be concluded that with the increasing amount of disintegrated face masks FFP2 in pellets, there was evident a significant increase of the content of C, H, and N, where C increased most significantly.…”

Environmental burden by burning waste in small heat sources

“…Linden leaves and maize husks had similar hydrogen content and linden leaves also similar nitrogen content. Mikeska et al stated the following contents: 47.46% for carbon, 5.65% for hydrogen, 0.09% for nitrogen and 39.12% for oxygen [6].…”

A Review of the Global Current Scenario, Trends, and Challenges of Hybrid District Heating System

“…As a result, new facilities with local fuels and various forms of process waste are increased. Waste is used more and more to create heat and power [34]. Biomass is derived from several sources, including Wild forest and woodland timber, Plantations of trees, Forestry byproducts, Straw, litter, and agricultural wastes are examples of agricultural residues, Sugarcane bagasse and rice husk are examples of agro-industrial waste, Waste from animals, industry, Sewerage, MSW (municipal solid waste) and Waste from food manufacturing shown in figure 7 [35].…”
