摘要:
A hydrogen reforming system includes a cyclical compression chamber having an entry port for receiving hydrogen-containing gas and an exit port for delivering reformed hydrogen-containing gas, an arrangement for heating the hydrogen-containing gas to a non-combustible temperature, and a drive system for cycling the cyclical compression chamber. The cyclical compression chamber has an operational cycle with an internal pressure and temperature absent combustion effective for reforming the hydrogen-containing gas.

A low emission turbine includes a reverse flow can-type combustor that generally includes a primary and secondary fuel delivery system that can be independently controlled to produce low CO, UHC, and NOx emissions at design set point and at conditions other than design set point. The reverse flow can-type combustor generally includes an annularly arranged array of swirler and mixer assemblies within the combustor, wherein each swirler and mixer in the array includes a primary and secondary fuel delivery system that can be independently controlled. Also disclosed herein is a can-type combustor that includes fluid passageways that perpendicularly impinge the outer surface of a heat shield. Processes for operating the can-type combustors are also disclosed.

A power generation system and method includes a first gas turbine system comprising a first combustion chamber configured to combust a first fuel stream of primarily hydrogen that is substantially free of carbon-based fuels. The first gas turbine system also includes a first compressor configured to supply a first portion of compressed oxidant to the first combustion chamber and a first turbine configured to receive a first discharge from the first combustion chamber and generate a first exhaust and electrical energy. The power generation system further includes a second gas turbine system comprising a second combustion chamber configured to combust a second fuel stream to generate a second discharge. The first compressor of the first gas turbine system is configured to supply a second portion of compressed oxidant to the second combustion chamber. The second turbine system also includes a second turbine configured to receive the second discharge from the second combustion chamber to generate a second exhaust and electrical energy and a second compressor configured to receive the second discharge comprising carbon dioxide. The second compressor is also configured to discharge a recycle stream to the second combustion chamber and a split stream to a separator system adapted to recover carbon dioxide.
