Abstract: A burner comprises a fuel distributor having a plurality of fuel injection holes through which a fuel gas is injected into a combustion space 3, an air injector 2 placed to surround the fuel distributor and having a plurality of air injection holes through which air is injected into the combustion space 3, a temperature detector placed such that a temperature detecting portion at a tip end thereof is located within the air injection hole, a body portion thereof is contained within the air injector, and an air layer is formed between the temperature detector and an inner wall of the air injector 9, and a flame detector connected to the temperature detector, for detecting a flame condition based on temperature information within the combustion space which is obtained from the temperature detector.

Abstract: A liquid fuel burning device suitable for kerosene stove, kerosene kitchen range or the like. The device has an inner and outer flame sleeves each having a multiplicity of pores and a wick interposed between these sleeves. The wick has a fuel evaporating portion projectable into the annular burning space formed between these sleeves. At least one of these sleeves is provided with at least one vertical row of air pores in its portion facing the fuel evaporating portion of the wick. Above the region of vertical row of air pores, formed is a horizontal row of air pores having a multiplicity of pores arranged at a higher density than the pores in the other portion of the wall. In the case where the vertical and horizontal rows of air pores are formed in the inner flame sleeve, a partition plate having apertures is attached to the inner side of the inner flame sleeve at a level above the horizontal row or air pores.
