Definitions

  • the present invention relates to a novel burner for the combustion of solid fuels, in particular, but not exclusively wood chips and pellets that may have 14961-2 melting temperature of the ash also lower than required by the class A2 according to the EN is provided.
  • solid fuels in particular, but not exclusively wood chips and pellets that may have 14961-2 melting temperature of the ash also lower than required by the class A2 according to the EN is provided.
  • pellets of agricultural wastes, peat, and others which have a melting temperature of the ash below 1 100° C.
  • a pellet burner which is provided for the combustion of solid fuels, particularly pellets.
  • the burner has arranged mutually parallel at mutual distances hollow grate bars. is primary air through the hollow grate bars in the under these ash space and contained passed between the hollow grate bars and over the arranged in front of the hollow grate bars perforated front plate in the combustion chamber.
  • patent KR 100541280 with the Rost lenderssvorrichting with a moving between grate bars, a circular motion applying cleaning comb.
  • This construction has the following disadvantages:
  • the cleaning comb cannot clean the surface of the grate bars which are unmitelbar between the blades of the cleaning comb.
  • the ash falls not only on the Rosstäbe, but also on the moving parts, such as chain wheels, chain, shaft, and drive, and causes an intensive wear.
  • the U.S. Pat. No. 1,441,293 a burner with two pistons is known.
  • the lower piston is connected to a member of the thrust grate, the primary air comes to the sliding grate by an opening in the lower piston.
  • the upper piston is used to Brennstoffnach committee and has no air hole. Thus, it is high temperatures loaded.
  • the advantages achieved with the invention consist in particular in that the glow and the fused ash lying on the grate are agitated by the cleaning comb.
  • two effects are achieved: more complete combustion of the fuel and crushing of the slag before it has hardened.
  • the ash and the Schiacke are discharged from the burner.
  • the plaster comb always leads through the grates move through in one direction only to burner opening, and the grates, the movement of which takes place burner opening back.
  • the Accommodate of fuel on the grate bars by means of a piston.
  • the piston includes in his stoppage the opening of the hopper, and thus forms the back fire protection.
  • the piston has at least one secondary air supply at the end face. Thanks to the air flowing through the air piston piston and the piston channel to be cooled, and thus prevents adhesion of fuel particles.
  • the funnel has a back fire damper whose Aufhticianachse is arranged so that the return fire damper comes to rest on the slide wall.
  • the return fire damper closes the hopper and opens only when fuel from above suppressed.
  • All moving Teiie of the burner are located in that has passed combustion air zones and thus be cooled.
