A compact burner-boiler combination having an improved heating cycle for effecting substantial fuel saving and maximum boiler and combustion efficiency in a relatively simple and expedient manner. This is attained by a compact boiler construction utilizing an improved burner construction and method of combustion in which a liquid fuel is gasified by the heating products of combustion to form a homogeneous fuel gas-air mixture prior to combustion so as to effect a substantially stoichiometric burning of the fuel so as to result in a high velocity and a very high flame temperature (approx. 4100°F.) and to cause the breakdown of a portion of the hydrocarbons into their basic component elements so as to make them available for diffusion burning. A small percentage or air is thereafter introduced tangentially into the burner flame to create the diffusion burning of the free hydrogen and carbon generated by the combustion process to produce a hot luminous optimum flame pattern and to maintain the high surface velocity so as to attain maximum transfer of heat energy to the heat transfer surfaces of the boiler by both radiation and conduction.

A burner for burning a gasifiable liquid fuel comprising a burner nozzle having an inlet and an outlet, a mixing chamber connected in communication with said inlet; means for introducing combustion air into said mixing chamber under pressure whereby the velocity of the combustion air through said mixing chamber creates a zone of reduced pressure in said mixing chamber, said nozzle having a gas return port adjacent to the outlet of said nozzle, and a return tube interconnected between said gas return port and said mixing chamber whereby the zone of reduced pressure in said mixing chamber induces a flow of hot combustion gas through said gas return port and connected return tube to said mixing chamber, means for introducing a liquid fuel into said return tube whereby the hot gases of combustion effect the gasification of the liquid fuel prior to said fuel entering into said mixing chamber to mix with said air to form a combustible gaseous mixture; ignition means disposed relative to said nozzle to effect ignition of said combustible gaseous mixture, whereby a flame having a high flame velocity and very high flame temperature is achieved so as to cause a break down in a portion of the hydrocarbons into their basic elements hydrogen and carbon, and a means disposed adjacent to the outlet of said burner nozzle for directing an air stream in a generally tangential direction relative to the longitudinal axis of said nozzle and burner flame therein whereby said air stream effects the diffusion burning of the free hydrogen and carbon and the maintaining of said velocity.
