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.
