This paper studies the SO2 and NOx emissions from coal oxy-firing in bubbling fluidized bed combustors. The influence of temperature excess oxygen is measured discussed. results are also compared with conventional air combustion, order to determine whether contributes increase emission levels. Two completely different coals, Central Europe bituminous domestic Spanish high-sulfur lignite, have been tested CIRCE 90 kW combustor. Although literature data scarce, a comparison findings research...
Integrating bioenergy into carbon capture and storage systems (Bio-CCS) is a novel concept aiming at reducing CO2 emissions, pointing to short-term need increase the use of non-conventional biomasses. The main objective this experimental research characterize behavior two agro-waste biomasses under oxy-co-firing conditions, as concerns fuel conversion NO formation, compared typical raw pine wood. effect replacing with H2O in firing atmosphere also sought. Two different biomass shares blends,...
Along with SO2, NOx emissions are considered the main pollutants from solid-fired combustion systems. In fluidized-bed boilers, injection of limestone pursues SO2 retention, achieving capture efficiencies over 90%. Nevertheless, CaO formed calcination has been identified as a catalyst N-compound reactions, increasing NO emissions. This paper investigates effect addition on under oxy-fired conditions, well influences bed temperature, O2 concentration in fluidizing gas, and excess oxygen. To...
The combined use of bio-fuels along with CO2 capture techniques is the basis for so-called negative emissions energy systems. In this paper, oxy-fuel combustion two torrefied biomasses experimentally investigated in a lab-scale entrained flow reactor. are fired alone, and co-fired coal (50%). Two oxygen concentrations (21% 35%) four steam tested: 0% (dry recycle oxy-combustion), 10% (wet 25% 40% (towards concept oxy-steam combustion). tests designed to get same mean residence time all fuels...
