A nozzle block for injecting secondary air into the combustion chamber of a solid fuel boiler, a combustion chamber, a burner system and a solid fuel boiler

摘要

the invention relates to a block (32) nozzles for injecting secondary air (a) into the combustion chamber (20) for heating the boiler (10) for solid fuelcontaining at least one constantly open an insertion hole (321) with longitudinal axis (322) pass through the hole, adjusted for the heating gases (in) entrained flow system (30).at least one inlet hole (323) for introducing secondary air (s) in the block (32) nozzles.at least one output port (324) for introducing secondary air (s) in the at least one pass through hole (321) and block (32) nozzles has a contour cross section which is formed in order toso basically all přehrazoval internal cross section of the combustion chamber (20), whereby the at least one pass through hole (321) is kept open.the invention further relates to a combustion chamber containing a block (32) nozzles.entrained flow system comprising a block (32) nozzles and heating boilers for solid fuel containing the combustion chamber and hořákový system.
