Definitions

  • the invention relates to a firing device for the combustion of solid fuels, in particular for the combustion of waste materials.
  • This object is achieved according to the invention in that a primary combustion device which receives the solid fuels and causes their gasification is followed by a separate secondary combustion device for burning the fuels present in the gaseous state, the secondary combustion device preferably being a combustion gas chamber connected to the combustion chamber of the primary combustion device as well as an adjoining main combustion chamber.
  • the already partially burning gases coming from the primary combustion devices, the secondary combustion air quantities necessary for the secondary combustion and, if necessary, a recycle exhaust gas quantity which is favorable for NOx reduction can be mixed in and thus achieve an optimal one Burnout mixture are prepared. Thereafter, the processed fuel gases flow into the main combustion chamber of the secondary combustion device, where they can burn out completely at moderate flow speeds and balanced temperatures.
