The report gives results of an evaluation of a multistaged combustion burner (designed for in-furnace NOx control and high combustion efficiency) for high nitrogen content fuel and waste incineration application in a 1.0 MW package boiler simulator. A low NOx precombustion chamber burner has been reduced in size by about a factor of two (from 600 to 250 ms first-stage residence time) and coupled with air staging, resulting in a three-stage configuration, and natural gas fuel staging, yielding up to four stoichiometric zones. Natural gas, doped with ammonia to yield a 5.8% fuel nitrogen content, and distillate fuel oil, doped with pyridine to yield a 2.0% fuel nitrogen content, were used to simulate high nitrogen content fuel/waste mixtures. Under the conditions tested, net chemical destruction of NO via reburning does not seem to be evident. This may be due to the existence of rather low primary NO concentrations before the application of reburning. However, a beneficial dilution caused by reburning may provide lower NO emissions.
