US 5,964,585 A · Oil burner for ensuring combustion of long-term stored kerosine

Abstract

An oil burner capable of ensuring normal combustion of quality-deteriorated kerosine. A burner body including a vaporization section is fed with fuel and air from a fuel pump and an air fan, respectively. A combustion control unit controls the fuel pump and air fan to control a combustion quantity in the burner body. The combustion control unit increases the combustion quantity to a combustion level sufficient to permit tar collected in the vaporization section to be burned at a predetermined time interval. Also, the combustion control unit keeps the combustion quantity increased to the combustion level for a predetermined period of time which permits tar collected in the burner body prior to an increase in combustion quantity to the combustion level to be substantially exhausted. This permits the combustion quantity to be intermittently increased, to thereby ensure substantial exhaustion of tar collected in the burner body.

Dependent claims

An oil burner for ensuring normal combustion of quality-deteriorated kerosine used as a fuel therefor, comprising:

a burner body for burning the fuel which includes a vaporization section for vaporizing the fuel;
a fuel pump for feeding said burner body with the fuel;
an air fan for feeding said burner body with air;
and
a combustion control unit for controlling said fuel pump and air fan to control a combustion quantity in said burner body;
said combustion control unit being constructed so as to increase said combustion quantity to a combustion level sufficient to permit tar collected in said burner body to be burned at a predetermined time interval and keep said combustion quantity increased to said combustion level for a predetermined period of time which permits tar collected in said burner body prior to an increase in combustion quantity to said combustion level to be substantially exhausted.
