Combustion device

Abstract

The present invention pertains to a combustion device which is mounted to a wood boiler or the likes and generates high thermal power while decreasing soot by means of a simple structure. According to the present invention, a combustion device comprises; a main body having a porous plate which is formed inside and on which injected fuel is stacked; a fuel injection section communicating with one side of the upper portion of the main body; a first air supply section communicating with the lower portion of the porous plate of the main body and supplying air; an ignition section formed to be adjacent to the porous plate and igniting the fuel; a flame discharge section extending from the other side of the upper portion of the main body and discharging the flame and heat caused by the combustion; a cyclone section formed in the shape of a short cylinder and expanding in a lateral direction from the periphery of the flame discharge section so as to partially expand the path of the flame discharge section; and a second air supply section communicating with one side of the periphery of the cyclone section and supplying air to the cyclone section in a tangential direction.

1 . A combustion device comprises; a main body having a porous plate which is formed inside and on which injected fuel is stacked; a fuel injection section communicating with one side of the upper portion of the main body; a first air supply section communicating with the lower portion of the porous plate of the main body and supplying air; an ignition section formed to be adjacent to the porous plate and igniting the fuel; a flame discharge section extending from the other side of the upper portion of the main body and discharging the flame and heat caused by the combustion; a cyclone section formed in the shape of a short cylinder and expanding in a lateral direction from the periphery of the flame discharge section so as to partially expand the path of the flame discharge section; and a second air supply section communicating with one side of the periphery of the cyclone section and supplying air to the cyclone section in a tangential direction. 
     
     
         2 . A combustion device of  claim 1 , wherein the flame discharge section has a tapered inner portion between the main body and the cyclone section to restrict the backward air flow. 
     
     
         3 . A combustion device of  claim 1 , wherein the fuel injection section is formed in the shape of tube, and a backfire prevention air injection hole is formed on the periphery of the fuel injection section. 
     
     
         4 . A combustion device of  claim 2 , wherein the fuel injection section is formed in the shape of tube, and a backfire prevention air injection hole is formed on the periphery of the fuel injection section. 
     
     
         5 . A combustion device of  claim 1 , wherein small holes are formed on the periphery of the cyclone section to exhaust the ash generated after combustion. 
     
     
         6 . A combustion device of  claim 2 , wherein small holes are formed on the periphery of the cyclone section to exhaust the ash generated after combustion.
