Originální abstrakt

A built up numerical model represents the afterburner channel in a two-chamber biomass boiler with capacity 200 kW. The boiler is designed for combustion of very moist biomass. The trace gas was used for identification of mixing quality. The trace gas was virtually distributed in separate points in front of the duct. 3D concentration fields in the duct were computed. 2D concentration fields in the cross section led in the end of the duct was used for evaluation of mixing quality. Target of carried out parametrical studies was to find out an optimum shape of an afterburner channel which could provide maximum mixing of combustion air flow with a flow of flue gas and combustible components in volatile matter. Adjustments to the channel shape can help to increase combustion efficiency and decrease emission production (especially CO, particulate matter and organic gaseous compounds). A local acceleration of the flow was used for encouragement of mixing process in the duct. Different size of cross section windows was tested and compared from the view of mixing quality.
