Abstract (en)

[origin: CA2746826A1] The invention relates to a method for cascaded biomass oxidation in a dish burner with ejection firing. The fuel (18), together with oxygen-containing primary air, is fed to a gasifier dish (8) having high thermal conductivity, in which the fuel is gasified by pyrolysis in a first combustion step, the resulting gas is conducted through guiding devices (6, 9) over the dish edge (11) of the gasifier dish, or over recesses on the upper dish edge, to the outside wall of the dish (8), and is enriched with oxygen-containing secondary air in the intermediate chamber (10) and converted into a cyclone flow around the outer shell dish during a second combustion step, through the convection of which strong thermal feedback is created, together with the high reflection of the thermal radiation on the guiding devices.
