摘要： 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.

摘要： A method for characterizing the parameters of a normally occurring turbine exhaust gas temperature profile is provided. From that characterization the characteristics of a filter function to eliminate or significantly reduce the strength of aliased signals from that normally occurring pattern are established. Sensors to provide filtering functions for that purpose include a distributed gradient thermocouple system and a resistance thermometer system. Examples of such sensor systems are disclosed. The method and related sensors improve the detection limits associated with exhaust gas temperature profiles used to monitor, diagnose, and control gas turbines.

摘要： A fuel cell module includes at least one fuel cell stack comprising a number of fuel cell units. An inlet is configured to receive an oxidant flow for supplying the fuel cell stack. An outlet is configured to exhaust an exhaust oxidant flow generated by the fuel cell stack. A recirculation path is configured to convey at least about thirty percent (30%) of the exhaust oxidant flow from the outlet to the inlet as a recirculated exhaust flow, for combination with the new oxidant flow to form the oxidant flow to the fuel cell stack.

摘要： A flow control device for a combustor is provided in which the flow control device comprises a shroud having a first end and a second end wherein the second end is coupled to the combustor. The shroud is disposed to receive a primary fluid and disposed to direct the primary fluid into the combustor. In addition, the shroud further comprises a plurality of ports disposed therein wherein the ports are oriented to extract a portion of a flow from a flow path of the primary fluid so as to control a flow rate of the primary fluid through the shroud.
