NATURAL GAS REBURN FOR EMISSIONS REDUCTION

2012-7-11 · natural gas reburn to a front-wall fired boiler is shown schematically in Figure 1. In the primary zone, pulverized coal is fired through conventional or low-NOx burners operating at low excess air. In this zone it is important to obtain the complete combustion of the coal and thus produce NOx from the fuel-nitrogen, and, prompt and thermal NOx.

Fuel Staging for NOx Reduction in Biomass

2019-5-26 · With increasing use of biomass in combustion processes, the reduction of the related NOx emissions which originate mainly from the fuel nitrogen becomes more and more important. Efficient primary measures for NOx reduction are staged combustion techniques. Air staging has been investigated earlier and has found its way into practice. Since fuel staging has not been applied with
