Prediction of Flue Gas Composition and Comparative

2018-7-21 · A set of conditions was simulated with ASPEN PLUS software, including air and oxyfuel (OF) combustion of carbonate-rich unconventional fuels: Estonian oil shale (EOS) and Utah White River oil shale (UOS). For OF combustion cases, two different flue gas recycle (FGR) strategies were applied by controlling the O2 percentage in the flue gas on the basis of maintaining similar temperatures at the

Experimental investigation on flue gas emissions of a

Flue gas emission concentrations were measured by gas analysers. If the flow rate of the flue gas is known, quantitative analyses of the emissions could be done easily. When the biomass boiler is in operation at its design load with a flue gas O 2 concentration of 6%, the dry flue gas flow rate was estimated to be ∼550 l (at 15°C and 1 atm)/min.

2012-7-25 · Flue gas temperature is an indication of how effectively combustion heat is being transferred to the boiler water. In general, lower flue gas temperature indicates better heat transfer and higher overall efficiency. It means that less energy is going up the stack and, everything else being equal, more is going into the water.
