Abstract: Given that sulfur contents of coals vary widely, this work investigated whether cofiring of highsulfur coals with lowsulfur coals of different ranks has any distinct advantages on lowering the sulfur dioxide emissions of ...

Abstract: Combustion-generated emissions of acid gases, such as nitrogen-bearing species, constitute environmental pollutants and some are subjected to environmental regulations. Assessment of such emissions is important to decide ...

Abstract: Elevated emission of hydrogen chloride (HCl) from the combustion of biomass in utility boilers is a major issue, as it can cause corrosion, and in combination with the high alkali content often encountered in these fuels, ...

Abstract: Activated coke was prepared by mixing sewage sludge and waste poplar bark biomass from furniture manufacturing. The physical activation method of these feedstocks with steam for 1 h at 850 °C was implemented. The elemental ...

Abstract: This is an investigation on the effects of pyrolysis atmosphere on the conversion of biomass/coal blends to chars and volatile matter, and on the release of sulfur and nitrogen to the gas phase. Pulverized corn straw and ...

Abstract: Coal and biomass are regularly used in the preparation of activated coke. In this paper, coal and biomass (poplar bark) were co-pyrolyzed, and activated coke was prepared by physical “one-step activation,” followed by ...

Abstract: Chlorine plays an important role in the slagging and corrosion of boilers that burn high-chlorine content biomass. This research investigated the emissions of hydrogen chloride (HCl) gas from combustion of biomass in a ...

Abstract: Flue gas recirculation (FGR) is an effective method to reduce NOx emissions from the combustion of fuels, such as natural gas. Nitrogen, carbon dioxide, and water are the main components of flue gas. Nitrogen is an inert ...
