Systems and methods for an oxy-fuel type combustion reaction are provided. In one or more embodiments, a combustion system can include at least two mixing zones, where a first mixing zone at least partially mixes oxygen and carbon dioxide to produce a first mixture and a second mixing zone at least partially mixes the first mixture with a fuel to produce a second mixture. The combustion system can also include a combustion zone configured to combust the second mixture to produce a combustion product. In one or more embodiments, the first mixture can have a spatially varied ratio of oxygen-to-carbon dioxide configured to generate a hot zone in the combustion zone to increase flame stability in the combustion zone.

Combustor systems and combustion burners for combusting a fuel

The present invention comprises methods for detecting and controlling flame blowout in combustors. The blowout precursor detection system comprises a combustor, a blowout precursor detection unit, a pressure measuring device and/or an optical measuring device. The methods of the present invention comprise receiving optical data measured by an optical measuring device, performing one or a combination of raw data analysis, spectral analysis, statistical analysis, and wavelet analysis on received optical data, and determining the existence of a blowout precursor based on such analyses. The present invention further comprises closed-loop control methods for controlling a combustor to prevent blowout.

Systems and methods for detection and control of blowout precursors in combustors using acoustical and optical sensing

A method for combusting a combustible fuel includes providing a vessel having an opening near a proximate end and a closed distal end defining a combustion chamber. A combustible reactants mixture is presented into the combustion chamber. The combustible reactants mixture is ignited creating a flame and combustion products. The closed end of the combustion chamber is utilized for directing combustion products toward the opening of the combustion chamber creating a reverse flow of combustion products within the combustion chamber. The reverse flow of combustion products is intermixed with combustible reactants mixture to maintain the flame.

Stagnation point reverse flow combustor

A combustor assembly includes a combustor vessel having a wall, a proximate end defining an opening and a closed distal end opposite said proximate end. A manifold is carried by the proximate end. The manifold defines a combustion products exit. The combustion products exit being axially aligned with a portion of the closed distal end. A plurality of combustible reactant ports is carried by the manifold for directing combustible reactants into the combustion vessel from the region of the proximate end towards the closed distal end.
