Embodiment Construction
[0048] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a longitudinal sectional view showing the main part of the core lift type oil burner of the present invention. This core lifting type petroleum combustion equipment 1 has: a fuel tank 7, which is fixed on a setting plate 3 via a plurality of supporting feet 5, wherein the setting plate 3 is placed on a set surface such as a floor; a burner main body 9, which Arranged on the upper part of the combustion tank 7; a combustion core storage structure 11, a part of which is disposed in the fuel tank 7, and the rest is disposed in the burner body 9; a combustion core 13; a combustion tube structure 15. Refined kerosene is charged in the combustion tank 7 as liquid fuel. Most of the components (3 to 15) other than the combustion core 13 are formed by machining a metal plate. The burner body 9 includes a cylindrical body 9A whose upper end opening is closed by a t...

The present invention provides a core lift type petroleum burner which can obtain a stable burning state. A baffle part (57) without a hole at the central part is formed on a reinforcing plate (55). The baffle part all change the air which ascends along a central line (CL) to a direction that faces the radial outer side of an internal flame cylinder (47), wherein the central line extends along thevertical direction of an inner-core cylinder (17). One part of the air with changed direction flows into a clearance through a plurality of air holes (48) which are formed at an area below a reinforcing plate, wherein the reinforcing plate is formed at the inner flame cylinder and is fixed in the inner flame cylinder. Additionally, the residual part of the air with changed direction flows into the inner flame cylinder through a plurality of through holes (55) formed on the reinforcing plate. The total opening area of air holes (48, 50) provided in the inner flame cylinder and the outer flamecylinder are enlarged, and simultaneously the total opening area of through holes (56) provided in the reinforcing plate is reduced. The reinforcing plate is provided in the inner flame cylinder.
Description
technical field [0001] The present invention relates to a core lift type oil burner with a combustion core. Background technique [0002] An example of the structure of the conventional core lift type oil burner is disclosed in Japanese Mikosho 63-39527 A. The burner has a combustion wick arranged between the core inner cylinder and the core outer cylinder so that the liquid fuel (refined kerosene) sucked up from the lower part is vaporized at the upper end. Moreover, the burner has an inner flame tube and an outer flame tube on the core inner tube and the core outer tube. The inner flame tube and the outer flame tube are arranged at intervals to form a gap facing the upper end of the combustion wick, and are respectively formed with a plurality of air holes for introducing air into the gap. A reinforcing plate (or partition plate) is fixed inside the inner flame cylinder, and the reinforcing plate has a plurality of through holes through which the air that rises naturally...
