Abstract:Reburning was applied to Polish automatic coal-fired retort boiler (25 kW). The use of bio-syngas reduced NOx emissions from the boiler by over 25%, below the significant level of 200 mg/m3. Reburning was carried out using an integrated system consisting of the boiler and a fixed-bed 60 kW (GazEla) gasification reactor. The process gas was continuously introduced above the coal burner of the boiler. The process parameters of the boiler and the gasifier were also measured and compared with the other units. Characteristic NOx emissions from automatic and manually operated boilers were also presented.

 

Key words: NOx; reburning; coal combustion; biomass gasification
