LIQUID FUEL BURNING DEVICE

摘要

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. The ratio of the total area of apertures in the partition plate is selected to be smaller than 20% of the horizontal cross-sectional area of the inner flame sleeve as measured at the inner side of the latter.
