Abstract
The present invention provides a fuel incinerating system comprising a fuel injector, a multi-stage fuel-air mixing device comprising a plurality of fuel intake tubes stacked vertically and configured to provide annular gaps between one or more of the vertically stacked fuel intake tubes to entrain ambient air to form a fuel-air mixture; and a combustor in communication with the fuel-air mixing device and defining a combustion chamber and in communication with an ignition source. The combustor is configured to impede flow of the fuel-air mixture through the combustion chamber to achieve a desired retention time of the fuel-air mixture within the combustion chamber to achieve substantially complete combustions of the fuel.
Claims24
A fuel incinerating system comprising:
- a fuel injector configured to inject fuel at a predetermined velocity;
- a multi-stage fuel-air mixing device having an inlet end and an outlet end, the multi-stage fuel-air mixing device being in fluidic communication at the inlet end with the fuel injector to receive fuel injected from the fuel injector to be mixed with entrained air to form a fuel-air mixture,
- the multi-stage fuel-air mixing device comprising a plurality of fuel intake tubes stacked vertically, each intake tube having an inlet and an outlet, wherein the cross sectional area of the inlet of each intake tube is greater than the cross sectional of the outlet of a preceding intake tube, thereby providing an annular gap between two adjacent intake tubes for entraining additional air when the fuel-air mixture is passed from one intake tube into the adjacent intake tube;
- a combustor extending vertically from the multi-stage fuel-air mixing device, the combustor having an inlet portion in fluidic communication with the outlet end of the multi-stage fuel-air mixing device, and an outlet portion to exhaust products of fuel combustion, said combustor defining a combustor chamber between the inlet and the outlet portions;
- said combustor further in communication with a primary ignition source;
- wherein the combustor is configured to impede flow of the fuel-air mixture through the combustion chamber to achieve a desired retention time of the fuel-air mixture within the combustion chamber.
The incinerating system according to claim 2, wherein the combustor comprises two or more segmented combustion chambers each having an inlet portion and an outlet portion, wherein the first chamber communicates with the fuel-air mixing device and the primary ignition source to define a primary combustion chamber and subsequent segments define afterburners and are in communication with the outlet portion.

A method of enhancing incineration of a fuel, the method comprising:
- providing a vertically stacked multi-stage fuel-air mixing device in fluidic communication with a source of air at one end and a combustor at the other end,
- the multi-stage fuel-air mixing device including a plurality of fuel intake tubes stacked vertically, each intake tube having an inlet and an outlet, wherein the cross sectional area of the inlet of each tube is greater than the cross sectional area of the outlet of a preceding intake tube to provide an annular gap between two adjacent tubes for entraining additional air;
- injecting a fuel into the multi-stage fuel-air mixing device to achieve momentum/velocity for the mixed air and fuel to flow into the combustor and entraining additional air when air-fuel mixture being ejected into the adjacent fuel intake tube,
- impeding the flow of the mixed fuel and air through the combustor to achieve a desired retention time of the mixed fuel and air within the combustion chamber, thereby creating a fuel-air mixture having fuel to air ratio sufficient for substantially complete combustion of the fuel.
