Evaporation type burner

An evaporation type burner comprising;

• a combustion chamber which is a space defined by an inner side housing that is a bottomed cylindrical container consisting of a bottom wall and a peripheral wall,
• an impregnation member which is a member disposed at a first end that is an end on said bottom wall side of said inner side housing in said combustion chamber and having a capillary structure and/or porous structure,
• a fuel supply unit configured to supply fuel to said impregnation member and impregnate said impregnation member with said fuel, and
• an ignition device configured to heat and ignite vapor of said fuel evaporated from said impregnation member, wherein:
• said evaporation type burner further comprises a promotion member which is a member having many through-holes formed therein and being disposed a predetermined distance apart from said impregnation member on a second end side from said impregnation member in said combustion chamber, and said second end is an end opposed to said first end of said combustion chamber,
• said ignition device is disposed so as to be exposed to an ignition space which is a space located on the first end side from said promotion member in said combustion chamber,
• a first air supply opening configured such that at least a part of said first air supply opening opens into said ignition space and supplies air to said ignition space and a second air supply opening configured so as to open into a combustion space and supply air to said combustion space are formed in said peripheral wall of said inner side housing, and said combustion space is a space located on said second end side from said promotion member in said combustion chamber,
• said second air supply opening is constituted by either one or both of an air-supply aperture array formed in said peripheral wall and an air-supply slit formed in said peripheral wall, said air-supply aperture array is at least one array of a plurality of apertures formed a predetermined distance apart from each other toward said second end side from said first end side in a predetermined region of said peripheral wall of said inner side housing which defines said combustion space, and said air-supply slit is at least one slit formed so as to have a predetermined width and a predetermined length and extend toward said second end side from said first end side in a predetermined region of said peripheral wall of said inner side housing which defines said combustion space, and
• said evaporation type burner is configured such that a flow rate of air supplied to said combustion space through said second air supply opening on said second end side of said second air supply opening is larger than that on said first end side of said second air supply opening.
