Multi-variable optimization of pressurized oxy-coal combustion
… performed on a 300 MWe wet-recycling pressurized oxy-coal combustion process with carbon capture and sequestration. The model accounts for realistic component behavior such as heat losses, steam leaks, pressure drops, cycle irreversibilities, and other technological and economical considerations. …

Oxy-Coal Combustion: Submicrometer Particle Formation, Mercury Speciation, And Their Capture
… is the issue of great importance at the present. Coal, the cheapest and the most abundant reserve fossil fuel, is currently one of the most widely used energy source globally and will continue to be in the foreseeable future. The use of coal has also posed many world-wide environmental challenges, …

Design, integration schemes, and optimization of conventional and pressurized oxy-coal power generation processes
… potential and the high efficiency of pressurized oxy-coal combustion with carbon capture and sequestration for a zero emissions power plant (Zebian and Mitsos 2011). Besides the increase in efficiency, optimization with realistic operating conditions and specifications also shows a decrease in the …

Fine Particle and Mercury Formation and Control during Coal Combustion
<p>Pulverized coal combustion is widely used worldwide for the production of electricity. However, it is one of the primary emission sources of air pollutants, including particulate matter (fly ash) and mercury (Hg), into the atmosphere. This dissertation investigated three aspects of pollutant …

Gasification and combustion modeling for porous char particles
… effects of char gasification reactions during oxy-combustion of pulverized coal are not fully understood. The single particle char consumption model is used with output from CFD simulations of high-volatile oxy-coal combustion to analyze representative regions and trajectories along which char …

Oxygen-Enhanced Combustion: Theory and Applications
In the broadest sense, oxygen-enhanced combustion: OEC) refers to the use of oxygen to improve combustion and/or process characteristics. When a stream of oxygen is available, a wide range of flame configurations is possible. This work considers two specific configurations of OEC and is divided …
