Comparison of selected parameters of biomass and coal

Abstract

As a fuel, biomass differs in its properties from fossil fuels and acquisition thereof for energy purposes is limited; hence, the ongoing search for new bioenergetically useful plants. The article presents the results of physical and chemical analyses of seven species of perennial grasses: tall wheatgrass, tall wheatgrass ‘Bamar’, brome grass, tall fescue ecotype, reed canary grass, giant miscanthus, and sorghum. The research involved technical and elemental analysis as well as analysis of the ash composition performed in order to determine their potential use for combustion process. The measurement results were compared with those obtained for hard coal and agricultural biomass, which is widely used in the energy industry. The results suggest that perennial grasses can successfully be combusted with similar performance to coal if burned in appropriate combustion installations.

Evaluation of biomass quality of selected woody species depending on the soil enrichment practice

“…(Obernberger et al, 2006). The results of the experiment in this study have shown that the poplar and willow biomass contains lower values andfrom this perspective -these are better fuels than the other source of biomass Lalak et al, 2016;Obernberger et al, 2006) and bituminous coal (Cuiping et al, 2004).…”

“…The SRWCs biomass can contain several times less ash than the straw or grass biomass (Greenhalf et al, 2012;Lalak et al, 2016). Still, compared to coal, ash content in woody biomass can be up to a dozen times lower (Bowen and Irwin, 2008;Dincer and Zamfirescu, 2014).…”

Estimation of Energy and Emissions Properties of Waste from Various Species of Mint in the Herbal Products Industry

“…The high carbon content translates into increased energy parameters in the form of GCV and NCV for the studied biomass. M. × rotundifolia L., on the other hand, showed a similar carbon content to larch needles [41], tall fescue ecotype, sorghum [53], M. spicata L., and M. crispa L., and have a similar carbon content to apple tree leaves [54], Sudan grass [48], reed canary grass [53], and Virginia mallow [14]. It should be noted that the tested mint has a higher carbon content also in relation to Spire-mint, and the difference in relation to M. × piperita L. var.…”

“…Similar carbon content was found in Mentha × piperita L. var. citrata Ehrh.-'Bergamot' (the highest content among the tested plants) in relation to oak tree leaves [49], block wood [48], and Miscanthus [53]. The high carbon content translates into increased energy parameters in the form of GCV and NCV for the studied biomass.…”

“…The nitrogen content for M. × piperita L. var. citrata Ehrh.-'Bergamot' is comparable with rapeseed pods [41], almond prunings [48], and tall fescue ecotype [53], whereas M. spicata L. is comparable with Miscanthus [53], coconut coir, and corncob [48]. It is worth mentioning the high sulphur content obtained for M. × piperita L. var.…”
