In response to the Department of Energy’s (DOE) goals of developing low emission, coal-based power systems, Precision Combustion, Inc. is developing a low, single digit ppm NOx emissions system for high firing temperature IGCC systems. The present paper presents emissions data for syngas and alternate fuels tested successfully. Subscale testing results at 10 atmospheres include NOx emissions meeting DOE\u27s target of 0.01 lbs/MMBtu (3 ppm at 15% O2) and were below this value under some operating conditions during parametric testing
