Biomass Suspension Combustion: Effect of Two-Stage Combustion on NOx Emission…

A systematic study was performed in a suspension fired 20 kW laboratory-scale swirl burner test rig for combustion of biomass and co-combustion of natural gas and biomass. The main focus is put on the effect of two-stage combustion on the NO emission, as well as its effect on the incomplete combustion. When twostage combustion was applied, the NO emission level can be significantly reduced. …
