The present invention relates to a method and a device with fuel for combustion that is used in the sectors of industry, canteen and power plant, in particular, it relates to an energy-saving, efficient and environment-friendly fuel-combustion method and device. The combustion method is: 1) it contains an input port let the fuel enter into the furnace where the fuel is ignited to bring forth the incomplete combustion: 2) it contains another input port for adding the supplementary fuel to the furnace, which is mixed with the early-coming fuel that is burning to bring forth the complete combustion, 3) so the burning fuel experiences the phenomenon of cracking, gasification and expansion, but it is restrained in the boiler for compression, resulting in the fusion reaction for the purpose of perfect combustion; 4) Synchronized with the above steps, the air taken from the furnace side wall is mixed with the burning fuel in the furnace, which makes the heat generated in the furnace erupt due to the combustion. The present invention also discloses a method of a burner. The burner allows fuel combustion in the boiler to bring forth continuous repeated cracking, differentiation, gasification, expansion and compression, so the fuel molecules experience fusion reaction to release heat completely without release of thermal radiation, meanwhile, it significantly reduces the generation of all kinds of harmful gases. 1.

An oxygen transport reactor for boiler furnaces and gas turbine combustors that utilizes a liquid fuel that is oxidized as a gaseous fuel in a membrane reactor. A liquid fuel is introduced by vaporizing the fuel inside a porous pipe surrounded by an annulus reaction zone which is surrounded by an annulus air zone. An oxygen transport membrane separates the annulus reaction zone containing the porous vaporized fuel and sweeping CO 2 from the air feed side zone. Oxygen is transported from the outer annulus through the membrane to the annulus reaction zone containing the vaporized fuel and sweeping CO 2 . Fuel is first cracked to very small droplets in the intake fuel atomizer utilizing part of the intake CO 2 then completely vaporized inside the porous pipe utilizing the heat coming from the surrounding reaction zone. The oxygen transport reactor is applicable for carbon free boiler furnaces and gas turbine combustors which utilize oxygen transport reactors for combined oxygen separation and combustion.
