摘要： A method of combustor cycle air flow adjustment for a gas turbine engine according to the present invention solves the problem of a higher flame temperature in the combustor, thereby affecting the emission levels when a heat-recuperated air flow cycle is used to increase the compressed air temperature. In low emission combustors this impact is severe because emission levels are significantly dependent on the primary combustion zone flame temperature. The method of the present invention includes a step of changing a geometry of an air flow passage and thereby changing distribution of a total air mass flow between an air mass flow for combustion and an air mass flow for cooling in order to ensure that flame temperature in a primary combustion zone of a combustor are maintained substantially the same whether the gas turbine engine is manufactured to operate as a simple air flow cycle engine or as a heat-recuperated air flow cycle engine. In an embodiment of the present invention, the changing of the geometry of the air flow passage by changing the number and size of perforations in an impingement cooling skin so that with minimal changes the impingement cooling skin serves duel purposes both as a cooling device for cooling the combustor wall and as a valve means for combustor cycle air flow adjustment, which makes the method simple and economical.

摘要： A system and method for removing at least carbon from a fuel/air mixture prior to injection of the fuel/air mixture into a combustion system is disclosed. The system fully integrates the combined cycle power plant with carbon scrubbing of the fuel/air mixture to increase overall cycle efficiency while capturing carbon from the cycle. A portion of the compressed air source generated by the gas turbine compressor is provided to a premixer where it is mixed with a natural gas to form a fuel/air mixture. The fuel/air mixture passes through a catalytic partial oxidation (CPOX) reactor, which utilizes a precious metal to partially oxidize the hydrocarbons into carbon monoxide. The mixture passes through a shift reactor to complete generation of carbon dioxide and raise hydrogen yield of the fuel/air mixture. Carbon constituents are then removed from the mixture by a separator.

摘要： A gas turbine combustor having improved flashback margin is disclosed. Multiple embodiments of the present invention are disclosed including combustors having a single premix chamber as well as multiple premix chambers. Flashback margin is increased for the combustor by incorporating a means for introducing an inert gas, such as nitrogen, into the premix chamber(s) at the region proximate the boundary layer to purge the boundary layer of combustible mixture, thereby ensuring that no combustion reaction occurs in the boundary layer.

摘要： A cyclone combustor of the present invention uses a novel pre-mixture injection scheme to optimize performance. The cyclone combustor includes a cylindrical combustor can and three fuel/air premixing tubes entering the combustor can radially, with a tangential offset. The tangential offset is designed to provide an optimized circulation in the combustor can for improvement of liner life span, flame stability and engine turn-down. The ignition and pilot fuel systems are placed to take advantage of the premixing tube entry locations and the tangential direction of the mixture flow momentum in the combustor can. The special combination of the parallel axes of the combustor can and the mixing tubes provides a right angle between an outlet section and the major tube section of each premixing tube. The cyclone combustor of the present invention can meet the requirements for low NOx and CO emissions.
