Dexter Hydrocarbon (Oil) Burner, Patent Model

This model was submitted with the application for the patent issued to Thomas B. Dexter, of Lynn, Massachusetts (assignor of one-half his right to the Gilmanton Mills, Belmont, New Hampshire), August 19, 1879, no. 218619.
The model represents a tubular burner with a slightly reduced tip, provided with a vertical diaphragm that divides the burner into two sections. The space on one side of the diaphragm is connected to the oil line and to an air inlet pipe provided with a damper for adjusting the flow of air. The other space is connected to the steam line. In operation the flow of steam from the tip creates suction enough to draw the oil and air through the burner. The oil and air are heated by contact with the diaphragm, which separates them from the steam, and are intimately mixed when they issue from the burner. The diaphragm is notched just inside the tip so that the mixing of the steam and the air and oil results in the formation of a wide, thin, horizontal sheet. This produced a sheet of flame that spread over a large part of the furnace.
