Petroleum stove

Abstract

The present invention relates to a petroleum stove, more specifically to a recombustion device which prevents imperfect combustion after ignition and before normal combustion and burns combustion gas effectively, thereby enabling favorable heating. The present invention comprises: a stove body ( 20 ) in which a fixed core ( 23 ) is inserted in a core pipe ( 22 ), an oil supply controller ( 35 ) which is installed on the other side of a support ( 10 ) and connected to the core pipe ( 22 ) through a fuel supply pipe ( 36 ) supplying fuel from a fuel tank ( 37 ), and a recombustion unit ( 40 ) which is installed on top of a support cover ( 29 ) and includes a heat radiation unit ( 41 ) in which a recombustion chamber ( 42 ) is installed. The recombustion chamber comprises: an inner recombustion chamber ( 43 a ) which is formed in a cup shape, and an outer recombustion chamber ( 43 b ) which is formed in the shape of a cylinder with a wide top and narrow bottom with a bottom diameter less than the diameter of an outer combustion chamber ( 25 b ). The top of the outer recombustion chamber is closed with a cover ( 44 ) while the bottom is secured on the upper side of the support cover ( 29 ). The inner recombustion chamber is inserted in the outer recombustion chamber ( 43 b ) and the upper part thereof is fixed to the cover ( 44 ). Through holes ( 45 a, 45 b ) with a diameter of 6-8 mm are formed on the inner and outer recombustion chambers ( 43 a )( 43 b ) at intervals of 0.5-1.5 mm.
