Predicting gaseous emissions from small-scale combustion of agricultural biomass fuels

The use of conservation biomass feedstocks as potential bioenergy resources in the United Kingdom

“…NO x emissions are strongly correlated with flaming combustion (dominated by NO), accordingly reducing over the course of the run. NO x emissions were much higher for the Reed briquettes than for Ash logs, which is consistent with the higher fuel-nitrogen content as shown in Table 3 as is expected (Sommersacher et al, 2012;Mitchell et al, 2015;Amaral et al, 2014;Fournel et al, 2015). Willow char however does not follow that pattern: it has similar nitrogen content to the Reed briquettes, but during the combustion test it had slightly lower NO x emissions.…”

Proposta de emprego de conceitos de equilíbrio químico na descrição matemática da câmara de combustão de caldeira siderúrgica

“…Na literatura diversas pesquisas usam esta metodologia para predizer a composição de sistemas com muitas espécies e diversas fases em equilíbrio químico [9][10][11][12][13][14]. A energia de Gibbs total de um sistema fechado, à temperatura e a pressão constantes, diminui durante um processo irreversível e a condição de equilíbrio é atingida quando a energia de Gibbs alcança seu valor mínimo [15].…”

Extensive Operating Experiments on the Conversion of Fuel-Bound Nitrogen into Nitrogen Oxides in the Combustion of Wood Fuel

“…There is marked variability in the chemical composition of the biomass, which is also reflected in the marked dispersion of concentrations of nitrogen oxides in flue gases from biomass combustion. Because the current emissions limits for NO x from combusting biomass are not Experimental research and modelling of the fuel combustion processes can be used to clarify the formation of nitrogen oxides [3,4]. The combustion of forest biomass (dendromass) should be regulated so that nitrogen oxides emissions are minimized.…”
