“…The overall efficiency of the process on a thermal basis would be increased if the heat required for air preheating was recovered from the gas cooling section of the plant. Use of high temperature air as an oxidant achieves downsizing of the plant [42]. Downsizing is achieved because a smaller volume of air is needed to bring the gasifier to the required operating temperature, which in turn reduces the size of the reactor and gas cleanup system needed.…”

“…The development of advanced low-emission methods (e.g., oxy-fuel combustion [1,3,4] or synergetic gasificationcombustion systems [5]) will eventually decrease pollutant emissions (including NO x ). However, a current important problem is the abatement of NO x emissions from traditional air-fired combustion chambers.…”

“…Thermal efficiency, cold gas efficiency and carbon conversion efficiency are among the economic indicators while emission levels of CO 2 , SO 2 and NO x per unit of net power output are the environmental indicators (Christopher & Zhu, 2006;Sugiyama et al, 2005). Cold gas and carbon conversion efficiencies are measures of performance of the gasification section.…”

“…Most of the data are taken from a report of the Process Engineering Division of the American Energy Institute (Shelton & Lyons, 2000). The missing data relating to operating conditions and range of operating variables are retrieved from the literature (Booras & Holt, 2004;Christopher & Zhu, 2006;Osama, Akira, & Yoshinori, 2002;Polyzakis et al, 2008;Sugiyama et al, 2005). …”
