Abstract

Methods and systems for a gasifier system are provided. The gasifier system includes a first substantially cylindrically shaped conduit that includes a radially inner surface, a second conduit at least partially within and substantially concentrically aligned with the first conduit, and at least one support member extending between a radially outer surface of the second conduit and the radially inner surface of the first conduit wherein the support member is positioned along a length of the second conduit to facilitate reducing a vibratory response of at least one of the first and second conduits to a flow of fluid through at least one of the first and second conduits.

Description

technical field [0001] The present invention relates generally to integrated gasification combined cycle (IGCC) power generation systems, and more particularly to advanced methods and apparatus for injecting feedstock into gasifiers. Background technique [0002] At least some known gasifiers convert a mixture of fuel, air or oxygen, steam and / or lime into an output of partially oxidized gas, sometimes referred to as "syngas". The syngas is supplied to the combustors of gas turbine engines that drive generators that supply electrical power to the grid. Exhaust gas from the gas turbine engine may be supplied to a heat recovery steam generator that generates steam for driving the steam turbine. The power generated by the steam turbine also drives a generator that supplies electrical power to the grid. [0003] Fuel, air or oxygen, steam and / or lime are injected into the gasifier from separate sources through feed injectors that couple the feed sources to the feed nozzles. A...
