Abstract
A pot-type oil burner is disclosed which is capable of stabilizing the vaporization rate of fuel oil in a pot to accomplish the stable complete combustion with a good efficiency. The oil burner is constructed to arrange a heat-resistant fabric on the bottom surface of the pot to vaporize fuel oil with a constant rate. The oil burner is also capable of significantly reducing retention of tar in the pot and facilitates removing tar from the pot as desired.
Claims14
A pot-type oil burner comprising:
- a pot for carrying out therein not only the vaporization and mixing, but also the ignition and combustion of fuel oil supplied thereto;
- air supply means for supplying air to said pot;
- oil supply means for supplying fuel oil to said pot;
- an air pipe for introducing at least a part of the air flowing through said air supply means therethrough to said pot;
- an oil pipe for introducing fuel oil from said oil supply means therethrough to said pot;
- a fabric formed of a heat-resistant, oil absorbent fiber and spread on the bottom surface of said pot;
- heating means arranged in said pot immediately above said fabric for heating the interior of said pot and said fabric to a temperature sufficient not only to vaporize and mix, but also to ignite and combust therein, fuel oil supplied to said pot, said heating means being positioned sufficiently close to said fabric to cause ignition and burning of fuel oil vaporized by said fabric;
- and
- a nozzle means connected with said oil pipe for ejecting fuel oil into said pot, said nozzle means being positioned with respect to said air pipe so that said fuel oil is dispersed in the form of fine particles toward substantially the entire surface of said fabric by means of air supplied from said air pipe into said pot,
- whereby fuel dispersed toward said surface of said fabric is stably vaporized at a uniform rate and is ignited by said heating means.

A pot-type oil burner as defined in claims, 1, 2, 3 or 4, wherein said fabric is removeably arranged in said pot.
A pot-type oil burner as defined in claim, 1, 2, 3 or 4, wherein said fabric is formed into a reticulate shape and has an oxidation catalyst carried thereon.
A pot-type oil burner comprising:
- a pot having a plurality of through-holes formed at the side wall thereof to carry out not only vaporizing and mixing but also igniting and combustion of fuel oil supplied thereto;
- air supply means for supplying air to said pot;
- oil supply means for supply fuel oil to said pot;
- an air pipe for introducing a part of the air flowing through said air supply means therethrough to said pot;
- an oil pipe for introducing fuel oil from said oil supply means therethrough to said pot;
- a single pipe into which said air pipe and said oil pipe merge;
- a fabric formed of a heat-resistant, oil absorbent fiber and spread on substantially the entire bottom surface of said pot;
- a heating means arranged in said pot immediately above said fabric to heat the interior of said pot and said fabric to a temperature sufficient not only to vaporize and mix, but also to ignite and combust therein, fuel oil supplied to said pot, said heating means being positioned sufficient close to said fabric to cause ignition and burning of fuel oil vaporized by said fabric;
- and
- nozzle means provided at the end portion of said single pipe and positioned above said fabric to eject fuel oil carried on air therefrom toward substantially the entire surface of said fabric by means of air supplied from said air pipe into said pot.
