Generation of a Gaseous Fuel by Pyrolysis or Gasification of …

2009/9/1 · Cattle biomass (cattle manure) has been proposed for use as a reburn fuel for nitrogen oxide (NO x) emission reduction in coal-fired power plants and utility boilers. Cattle biomass (CB) has shown promise in reducing NO x due to its high volatile content, rapid release of volatile matter during combustion, and rapid release of fuel bound nitrogen predominantly in the form of ammonia (NH 3 ).

Evaluation of Wood Chip Gasification to Produce Reburn Fuel for …

Abstract Biofliels attract increasing interest in power plant technology as sources of carbon dioxide neutral fuels. Besides using solid pulverised biomass as an additional fuel in coal-fired boilers a further possibility to run a combined coal and biomass process is to pre-pyrolyse or pre-gasify biomass and to inject the gas as reburn fLiel into the coal-fired boiler.

Biomass gasification and Polish coal-fired boilers for process of reburning in small boilers …

2013/6/7 · Reburning was applied to Polish automatic coal-fired retort boiler (25 kW). The use of bio-syngas reduced NO x 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 …
