Classic Approach

The oxy-fuel combustion is recognizing one of the most promising available technologies that zero emission accomplishment may be in the offing. With coal burned at the pressure of 6MPa and oxygen-enriched conditions, the high temperature and high pressure gaseous combustion product is composed of mainly CO2and water-vapor that belonging to real gases. However, once lauded as classic approach of resolving fuel gas enthalpy calculation pertaining to ideal gas at atmospheric pressure was restrained by pressure limitations. In this paper, the flue gas was assumed as an ideal mixture of real gases system, and the equations for calculating the flue gas enthalpy were derived by using deviation function method based on the virial equation. Consequently, comparing with the results simulated by the flow-sheet simulation 2éÕÒ: software" software-ASPEN PLUS, it showed that calculation method on the basis of virial equation appears to be a reasonable enthalpy values for the pressurized oxygen-enriched coal combustion.

The U.S. Department of Energy is sponsoring a program of research and development on coal-fired heaters to provide heat input to the working fluid of a closed-cycle gas turbine/cogeneration system. One of the fired heater concepts being researched employs the atmospheric pressure fluidized bed coal combustion concept. This paper describes a research oriented atmospheric fluidized bed of 6- by 6-foot plan dimensions that has been designed and is being constructed for utilization during the R&D program. The design rationale is presented, details of the more significant details are described and discussed, and the planned methods for utilizing the 6- by 6-foot AFB as a research tool are presented.
