Abstract (en)
The invention relates to a method of discharging products of combustion from a burner pipe (2) of a solid fuel burner (1), whereby combustion gases formed during combustion are passed in and out from the burner pipe in a first direction (A), substantially coinciding with the center axis (C) of the burner pipe, wherein the combustion gases after having left the burner pipe (2) are redirected substantially 180 DEG and are subjected to a helical movement around the outer side of the burner pipe (2) while at the same time being conveyed back in a general second direction (B) along the outer side of the burner pipe (2), simultaneously emitting heat to a surrounding heat absorbing medium. <IMAGE>
Combustion gases and residue formed during combustion are conducted in and passed out from the burner (1) in a direction (A), coinciding with the burner pipe (2) center axis and afterwards are conveyed in a general second direction (B), back along the outer side of the burner while emitting heat to a surrounding heat absorbing medium. The combustion gases at the same time as they are redirected 180[deg] are subjected to a helical motion around the outer side of the burner pipe by means of an outer helix (3) fixed to its outer circumference. The combustion residue after having left the burner, are conveyed back along the outer side of the burner pipe in the general second direction through rotation of the burner pipe and the outer helix forming a feed screw. Independent claims are included for a combustion installation, and a burner for solid fuel consisting of a burner pipe.
