A portion of the exhaust generated by a turbomachine is recirculated through an inlet portion by an exhaust gas recirculation system. The system reduces the level of constituents within the exhaust before the exhaust is recirculated. The turbomachine may be utilized to drive the exhaust gas through the system.

Prime mover for an exhaust gas recirculation system

A method for controlling a turbomachine exhaust gas recirculation (EGR) system is provided. The EGR system may allow for the removal and sequestration of at least one constituent within the exhaust before the recirculation occurs.

Method for controlling a flowrate of a recirculated exhaust gas

A power generation system having an exhaust gas attemperating device and method for controlling a temperature of exhaust gases is provided. The exhaust gas attemperating device includes a first conduit and a venturi member. The first conduit is configured to receive at least a portion of exhaust gases from a gas turbine. The venturi member is disposed in the first conduit and defines a flow path therethrough for receiving the exhaust gases in the first conduit. The first conduit and the venturi member have an aperture extending therethrough communicating with the flow path, such that the exhaust gases flowing through the flow path draws ambient air through the aperture into the flow path for reducing a temperature of the exhaust gases flowing through the first conduit.

Power generation system having an exhaust attemperating device

A composition including a polycrystalline metal nitride having a number of grains is provided. These grains have a columnar structure with one or more properties such as, an average grain size, a tilt angle, an impurity content, a porosity, a density, and an atomic fraction of the metal in the metal nitride. An apparatus for preparing a metal nitride is provided. The apparatus may include a housing having an interior surface that defines a chamber and an energy source to supply energy to the chamber. A first inlet may be provided to flow a nitrogen-containing gas into the chamber. Raw materials may be introduced into the chamber through a raw material inlet. A second inlet may be provided to flow in a halide-containing gas in the chamber. The apparatus may further include a controller, which communicates with the various components of the apparatus such as, sensors, valves, and energy source, and may optimize and control the reaction.

Apparatus for making crystalline composition

A method of making a metal nitride is provided. The method may include introducing a metal in a chamber. A nitrogen-containing material may be flowed into the chamber. Further, a hydrogen halide may be introduced. The nitrogen-containing material may react with the metal in the chamber to form the metal nitride.

Method for making crystalline composition

The exhaust within an exhaust gas recirculation (EGR) system should be purged to allow for access to the components of the EGR system. A system and method for purging the EGR system is provided. The system and method may incorporate an: EGR purge fan, an EGR purge blower, or a turbomachine. The system and method may draw the exhaust out of the EGR system. The system and method may drive the exhaust out of the EGR system.

Purge system for an exhaust gas recirculation system

The exhaust within an exhaust gas recirculation (EGR) system should be purged to allow for access to the components of the EGR system. A method and system for controlling an EGR purge system is provided. The method and system may control the operation of drawing the exhaust out of the EGR system. The method may also control the operation of diving the exhaust out of the EGR system.

Control system for an EGR purge system

A method and system for controlling an exhaust gas recirculation (EGR) system is provided. The EGR system recirculates a portion of an exhaust through an inlet portion of the turbomachine. The EGR system reduces the level of harmful constituents within the exhaust before the recirculation occurs.

Method and system for controlling a flowrate of a recirculated exhaust gas

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.

Systems and methods for power generation with carbon dioxide isolation

Burner assembly for a cooking range is provided. The burner assembly includes a gas-heat subassembly, and a radiant heat subassembly. An electromechanical interface is configured to detachably interconnect the subassemblies to one another. The electromechanical interface is further configured to pass electrical power to the radiant heat subassembly.
