Definitions

  • Burner system in particular for biomass fueled
  • the combustion material located in the burner trough is acted upon only by the proportion of air, which flows at the outgoing from the fan, cyclone-like and directed against the fuel gas flow through the gas mixing chamber as a result of the central vacuum in the direction of the burner trough and in the burner trough back to the Fuel gas outlet is deflected. Accordingly, only a partial combustion takes place in the burner trough open only to the gas mixing chamber and in the gas mixing chamber itself, and the further burnout in the region of the fuel gas outlet and thereafter, whereby the combustion conditions are difficult to influence, since they also depend on the respective power of the blower device change.
