A hot oxygen burner (HOB) produces a reactive jet by combusting a small amount of fuel with an excess of oxygen and accelerating the combustion products through a nozzle. The resulting jet is very reactive due to high oxygen concentration, high temperature and exceptional mixing capability. Advantages achieved using an HOB system include simplified reactor design and the ability to engineer a syngas generation system for relatively small production applications while maintaining high performance levels.
Praxair has experimentally investigated HOB syngas generation at lab and pilot scales, at pressures ranging up to 400 psig, with feedstock variation including steam and CO2 addition. A broad spectrum of bench and pilot scale results are presented including syngas production efficiency, oxygen usage, product H2:CO ratio and quantitative measurements of minor species including soot, methane, acetylene, ethylene, ammonia and hydrogen cyanide. Experimental results are compared to detailed modeling of the hot oxygen process.
