20100255435 | LOW EMISSION AND FLASHBACK RESISTANT BURNER TUBE AND APPARATUS - A burner tube to provide combustible materials to a combustor is provided and includes an annular shroud and a center body, having a cavity defined therein, disposed within the annular shroud to form an annular passage, the annular passage being communicable with a combustion zone of the combustor at an aft portion thereof and including a fore portion in which fuel is injected into the annular passage. The center body includes a surface having a passage defined therein through which air is to be supplied to the annular passage from the cavity at a position, which is downstream from the fuel injection and upstream from the combustion zone. Also provided is a contouring of the centerbody. | 10-07-2010 |
20100275404 | ON-LINE CLEANING OF TURBINE HOT GAS PATH DEPOSITS VIA PRESSURE PULSATIONS - A method for removing hot gas deposits from a system via pressure pulses is provided. The method includes regulating a flow of a mixture of detonation fluid and oxidizer into an expansion chamber; and generating a detonation within the expansion chamber by igniting the mixture of detonation fluid and oxidizer in the expansion chamber producing a high-pressure wave, the high-pressure wave propagating along a fluid path of the system in a supersonic rate removing hot gas deposits in the fluid path while the system is in fired operation, the expansion chamber directing the high-pressure wave towards the fluid path of the system. | 11-04-2010 |

20140014186 | SYSTEM AND METHOD FOR PROTECTING GASIFIER QUENCH RING - A system includes a gasifier. The gasifier includes a reaction chamber configured to convert a feedstock into a synthetic gas, a quench chamber configured to cool the synthetic gas, and a transition section between the reaction chamber and the quench chamber. The gasifier also includes a quench ring configured to provide a first flow of a coolant to the quench chamber and a shielding gas system configured to provide a second flow of a shielding gas to protect at least one of the quench ring or the transition section. | 01-16-2014 |
20140061539 | GASIFICATION SYSTEM AND METHOD - A system includes a gasifier. The gasifier includes a chamber, a first nozzle, and a second nozzle. The first nozzle is configured to output a first fuel and a first oxidant to create a mixture that combusts in a combustion-reduction zone of the chamber. The second nozzle is configured to output a reduction promoter into the combustion-reduction zone to reduce combustion products in the combustion-reduction zone of the chamber. | 03-06-2014 |
20150148434 | SYSTEM AND METHOD FOR SEALING A SYNGAS COOLER - A system includes a syngas cooler and a compatible seal gas system. The syngas cooler may be configured to cool a syngas. The compatible seal gas system may be configured to supply a compatible seal gas to a seal of the syngas cooler. The seal may be configured to block the syngas from a passage between an outer wall of the syngas cooler and a tube cage of the syngas cooler. | 05-28-2015 |
20150175915 | SYNGAS COOLER - A system includes a gasifier that may gasify a feedstock to produce a syngas and a syngas cooler that includes a cooling chamber having a tapered configuration. The cooling chamber includes a first section that may separate particulates from the syngas and includes a first opening and a second opening. The first opening has a smaller width than the second opening. The system also includes a second section in fluid communication with the first section that includes a plurality of tubes surrounding the first section. A first portion of the plurality of tubes is arranged parallel to a longitudinal axis of the cooling chamber and a second portion of the plurality of tubes is angled such that the second portion of the plurality of tubes forms the tapered configuration. The system further includes a passage to flow a seal gas between a shell of the radiant syngas cooler and the second section. The shell encloses the cooling chamber. | 06-25-2015 |
