Impact of the crystallite parameters and coal ranks on oxidation and combustion properties of Carboniferous coals and Jurassic coals
TL;DR: In this article, two raw Xinjiang Jurassic coals (collected from Piliqing and Yuxing collieries, PLQ and YX) and two Shanxi Carboniferous coals were selected to explore the impact of crystallite parameters and coal ranks on the oxidation and combustion properties of coal fire.
Measurement and Analysis of Gas Composition in a Staged and Unstaged Oxy-Fired Pulverized Coal Reactor with Warm Flue Gas Recycle
TL;DR: In this article, Chase et al. measured and analyzed gas composition in a staged and unstaged oxy-fired coal reactor with warm recycled flue gas (420 F) to simulate conditions in an oxy-combustion coal boiler.

Oxy-Fuel Combustion - The Control of Nitrogen Oxides
TL;DR: In this paper, two combustion strategies for controlling the emission of NOx from oxy-fuel combustion: reburning and what we call "high-temperature reduction" were investigated, which is made feasible by the low concentration of nitrogen in oxyfuel combustion, which may reverse the Zeldovich mechanism (responsible for thermal NOx formation).

Experimental investigation on calcination/sulphation characteristics of limestone modified by acetic acid solution in O2/CO2 atmosphere
TL;DR: In this article, the effect of limestone modified by acetic acid solution on the calcination/sulphation characteristics was investigated in O 2 /CO 2 atmosphere, and the components of the sulphation product were determined by means of XRD analysis.

Simulation and Exergy Analysis of a 600 MWe Oxy-Combustion Pulverized Coal-Fired Power Plant
TL;DR: CO2 emission from pulverized coal-fired power plants (PC) can be efficiently controlled by adopting the oxy-combustion technology, which adds a cryogenic air separation process (ASU) and a flue gas treatment process (FGU) to the conventional combustion process.

Basic effects on NOx emissions in air staging and reburning at a bench-scale test facility
TL;DR: In this paper, the effects of stoichiometry and residence time in the fuel-rich zone and effects of temperature were evaluated for air staging with different coals and, in the case of reburning, for different gaseous reburn fuels.

Study on the Carbon-Nitric Oxide Reaction in the Presence of Oxygen
TL;DR: The surface nitrogen species were identified by X-ray photoelectron spectroscopy as pyridinic, pyrrolic or others as discussed by the authors, and it was found that the formation of surface oxygen complexes by the C-O[sub 2] reaction is essential for the carbon-nitric oxide reaction.

Selective catalytic reduction of NO over commercial DeNOx-catalysts: experimental determination of kinetic and thermodynamic parameters
M. Koebel,M. Elsener +1 more
TL;DR: In this article, the first-order rate law with respect to NO can only approximately describe the kinetic behavior of SCR catalysts and a much better description is possible by taking into consideration the adsorption of both NH 3 and NO.
