On this day in 1905 George L. Bourne was granted the patent for Hydrocarbon Furnace. U.S. Patent No. 793,622.
This invention relates to novel improvements in furnaces of the class in which crude petroleum or fuel-oil is employed as a fuel; an its object is to provide an economical and serviceable furnace of comparatively small size when required and promote the efficiency of this class of furnaces by producing a perfect combustion of the fuel, and thus secure the benefit of all the heat units contained therein. This result is obtained primarily by volatilizing and converting oil into a complete gaseous state in a primary combustion chamber and then introducing a blast of fresh air supply to the necessary additional oxygen to provide a perfect combustion in a secondary combustion-chamber, so that a high degree of perfect heat, free from uncombined carbon or oxygen, will be obtained in the heating-chamber, located, preferably, adjacent to the secondary combustion chamber.
