TL;DR: Oxy-coal combustion has generated significant interest since it was proposed as a carbon capture technology for newly built and retrofitted coal-fired power plants, and numerical models for sub-processes are also used to examine the differences between combustion in an oxidizing stream diluted by nitrogen and carbon dioxide as mentioned in this paper.

TL;DR: In this paper, the authors construct an analytical model to describe the dynamic response of a laminar premixed flame stabilized on the rim of a tube to velocity oscillation, and obtain a time-domain differential equation describing the relationship between the velocity perturbation and the heat release response over the entire frequency range.

TL;DR: In this article, the authors suggest that steps be taken to curb energy-related CO2 emissions through a number of technological solutions, which are to be implemented in a timely fashion, including substantial improvement in energy conversion and utilization efficiencies, carbon capture and sequestration, and expanding the use of nuclear energy and renewable sources.

TL;DR: In this paper, an oxy-fuel combustion power cycle that utilizes a pressurized coal combustor is analyzed and it is shown that this approach recovers more thermal energy from the flue gases.

TL;DR: In this paper, the authors review the progress made in understanding the effects of fuel composition on premixed gas turbine combustion, with a special emphasis on system stability and emissions, for hydrogen-rich synthetic gas (syngas) mixtures.
