Oil fired burner

An oil fired burner comprising a body including a lower end and an upper end defining an oil vaporizing chamber in which an oil vapor is produced, an inlet in the body for oil, an inlet in the body for air through which air enters the oil vaporizing chamber for mixing with the oil vapor in the vaporizing chamber to provide an oil vapor/air ratio such that the oil vapor is non-combustible, a baffle including an inner end facing the vaporizing chamber, an opposite outer end, and an aperture sized to receive the flow of the non-combustible oil vapor/air mixture therethrough, an air outlet adjacent the baffle feeding secondary air to the non-combustible oil vapor/air mixture to provide a second vapor/air ratio adjacent the outer end of the baffle such that the oil vapor is combustible, and a bed of imitation solid fuel positioned across the oil vaporizing chamber, whereby the mixture of air and the oil vapor will enter the fuel bed for combustion around the imitation solid fuel, vaporizing means being provided for initially vaporizing oil entering the oil vaporizing chamber through the inlet to provide an initial supply of the oil vapor for combustion around the imitation solid fuel.
