Control strategy for flexible catalytic combustion system

A control system for a catalytic combustion system on a gas turbine includes a flame preburner, a fuel injector positioned downstream of the preburner and a catalyst positioned downstream of the fuel injector. In such systems, a portion of the fuel combusts within the catalyst itself and the remainder of the fuel combusts in a homogeneous combustion process wave downstream of the catalyst. A sensor in communication with the control system monitors the homogeneous combustion process wave and adjusts the gas temperature at the catalyst inlet to a preferred value based on a predetermined schedule that relates the catalyst inlet gas temperature to operating fundamentals such as adiabatic combustion temperature or the gas turbine's exhaust gas temperature.

Paper arranging apparatus and electrophotographic image forming apparatus including the same

Provided are a paper arranging apparatus and an electrophotographic image forming apparatus. The paper arranging apparatus of an electrographic image forming apparatus has a driving roller and an idle roller facing closely to each other and forming a nip therebetween. A shutter arranges a sheet of paper by contacting a front edge portion of the paper before the front edge portion of the paper enters the nip and rotates after being pushed by the front edge portion of the paper to not interrupt the movement of the paper along the conveyance path. A flag is connected to a rotary shaft of the shutter to rotate in a same direction and at a same rotating angle as the shutter. A sensor senses position variations of the rotating flag and generates a signal representing a position of the paper that is being conveyed. The rotary shaft of the shutter is positioned to return the shutter to an initial position by being rotated in an opposite direction by its own weight after the paper has passed through the nip of the roller. The electrophotographic image forming apparatus having the paper arranging apparatus develops an image on an outer circumferential surface of a photosensitive medium and transfers the image onto a sheet of paper that is conveyed along a predetermined conveying path. The transferred image is fused onto the paper by a thermocompression method.

Laser controlled flame stabilization

A method and apparatus is provided for initiating and stabilizing fuel combustion in applications such as gas turbine electrical power generating engines and jet turbine engines where it is desired to burn lean fuel / air mixtures which produce lower amounts of NOx. A laser induced spark is propagated at a distance from the fuel nozzle with the laser ignitor being remotely located from the high temperature environment of the combustion chamber. A laser initiating spark generated by focusing high peak power laser light to a sufficiently tight laser spot within the fuel to cause the ionization of air and fuel into a plasma is unobtrusive to the flow dynamics of the combustion chamber of a fuel injector, thereby facilitating whatever advantage can be taken of flow dynamics in the design of the fuel injector.

Combustion device

In a combustion unit, a fuel collision member is disposed between a fuel injection valve and a combustion chamber. The fuel collision member is positioned so that, a part of fuel injected from said fuel injection valve is introduced into the combustion chamber while colliding with the fuel collision member, and the other part of fuel is directly introduced into the combustion chamber without colliding with the fuel collision member. Thus, fuel introduced into the combustion chamber is atomized while being introduced into the combustion chamber in a wide range.
