An oil burner of the heat radiation type is disclosed which is capable of effectively preventing clouding of the inner surface of a heat-permeable cylinder with moisture, contaminants contained in combustion gas such as soot and tar, and the like during at the ignition and combustion operation. The oil burner includes a communicating means for establishing the communication between an air supply passage and a space between a heat-permeable cylinder and an outer combustion cylinder, which comprises a top plate for a pot having through-holes formed at the portion thereof above the air supply passage and a top plate for a housing having through-holes formed at the portion below the space, to thereby allow air to be introduced directly from the air supply passage to the space and upward flow along the inner surface of the heat-permeable cylinder.

Heat radiation-type oil burner

A safety device for a pot-type oil burner is disclosed which is capable of efficiently and rapidly detecting the decrease of oxygen concentration in a room due to combustion to provide a warning and/or stop the combustion by sensing the decrease in temperature of a bottom portion of a pot. The safety device includes a thermo-sensitive device arranged on the outer surface of the bottom portion of the pot which is apart from the bottom region of the pot in which occurs the vaporization of fuel oil supplied to the pot.

Safety device for pot-type oil burner

A pot-type oil burner is disclosed which is capable of effectively preventing the generation of bad odor and soot during the igniting operation by turning on an electric heater positioned above a heat-resistant fabric spread on the bottom surface of a pot to previously heat the pot and fabric to a temperature sufficient to vaporize fuel oil prior to introducing fuel oil to the pot by means of a nozzle pipe.

Pot-type oil burner

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.
