A triple-vortex mixed-fuel vacuum burner-reactor comprising: an intake manifold, including a vacuum chamber, a compressed air nozzle inlet into the vacuum chamber, a compressed air nozzle entering into the vacuum chamber through the compressed air nozzle inlet, and an ejector outlet, wherein the intake manifold is configured to supply a gaseous fuel to a primary combustion chamber; the primary combustion chamber having a cylindrical exterior and having a conical interior, the conical interior having a first end with a smaller diameter and a second end with a larger diameter, the first end of the conical interior being connected to the intake manifold, the conical interior further including a first set of directing blades; a reduction nozzle connected to the second end of the conical interior of the primary combustion chamber, the reduction nozzle having a frustoconical first portion with a larger diameter connected to the primary combustion chamber and having a cylindrical second portion that extends from a smaller diameter of the frustoconical first portion; injectors perpendicular to the frustoconical first portion of the reduction nozzle configured to inject liquid fuel into the primary combustion chamber; and a cylindrical secondary combustion chamber having a second set of directing blades configured to direct air into the secondary combustion chamber, wherein the smaller diameter of the primary combustion chamber at its first end, the larger diameter of the primary combustion chamber at its second end and the first set of directing blades form three vortices of fuel in order to sustain rotation of the fuel to the exterior of the burner-reactor and slow transit of the fuels to allow for complete combustion. an intake manifold, including a vacuum chamber, a compressed air nozzle inlet into the vacuum chamber, a compressed air nozzle entering into the vacuum chamber through the compressed air nozzle inlet, and an ejector outlet, wherein the intake manifold is configured to supply a gaseous fuel to a primary combustion chamber; the primary combustion chamber having a cylindrical exterior and having a conical interior, the conical interior having a first end with a smaller diameter and a second end with a larger diameter, the first end of the conical interior being connected to the intake manifold, the conical interior further including a first set of directing blades; a reduction nozzle connected to the second end of the conical interior of the primary combustion chamber, the reduction nozzle having a frustoconical first portion with a larger diameter connected to the primary combustion chamber and having a cylindrical second portion that extends from a smaller diameter of the frustoconical first portion; injectors perpendicular to the frustoconical first portion of the reduction nozzle configured to inject liquid fuel into the primary combustion chamber; and a cylindrical secondary combustion chamber having a second set of directing blades configured to direct air into the secondary combustion chamber, wherein the smaller diameter of the primary combustion chamber at its first end, the larger diameter of the primary combustion chamber at its second end and the first set of directing blades form three vortices of fuel in order to sustain rotation of the fuel to the exterior of the burner-reactor and slow transit of the fuels to allow for complete combustion.
