Abstract: PROBLEM TO BE SOLVED: To provide a fuel stabilization system capable of removing dissolved oxygen from fuel to raise fuel temperature and being adapted to different demand conditions for removing oxygen. SOLUTION: This fuel stabilization system 10 is provided with a fuel tank 12 for supplying fuel to an engine 15 by a fuel pump 14. Dissolved oxygen is removed from fuel by a fuel stabilization assembly 16 provided with a plurality of oxygen removers 18, 20, 22, 24, 26 arranged in parallel. A part 30 of dissolved oxygen is removed from fuel by each fuel oxygen remover and is exhausted to the outside. Temperature of flowing-in fuel is within a scope of limit temperatures for preventing promotion of generation of insoluble substance under the presence of dissolved oxygen. Since fuel flowing out of the fuel stabilization assembly 16 contains less amount of dissolved oxygen, it is possible to heat fuel up to higher temperatures. Fuel is moved and heated by a heat transfer device 32. Efficiency of the engine is improved by improved temperature characteristic of fuel. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a mixer assembly 200 for a gas turbine engine 10.SOLUTION: The mixer assembly 200 includes a main mixer 220 and a pilot mixer 210 concentrically arranged with respect to the main mixer. The main mixer encloses at least part of the pilot mixer. The pilot mixer includes an annular housing 212 defining a cavity 208 to be partitioned from the main mixer. The housing has a front portion 202 and a rear portion 204, a diameter of the rear portion being larger than that of the front portion. The pilot mixer further includes a fuel nozzle 152 enclosed by the front portion of the housing and a partition 214 located downstream of the nozzle and connecting the front portion to the rear portion of the housing. The partition 214 is substantially perpendicular to the rear portion 204 of the housing and defines a corner 206 between the rear portion and the partition.

Abstract: A method and device of this invention includes a fuel deoxygenator and a heating device for removing dissolved oxygen from fuel and then heating that fuel to a temperature above the temperature that would otherwise produce undesirable insoluble materials from a hydrocarbon fuel. The temperature of the fuel and the amount of dissolved oxygen that is removed from the fuel are adjusted according to the combustion process and optimization of desired combustion characteristic s.

Abstract: A fuel stabilization system includes a first deoxygenator and a second deoxygenator both for removing dissolved oxygen from a hydrocarbon fuel. The first and second deoxygenators are arranged in parallel or series to sequentially remove a portion of dissolved oxygen from the hydrocarbon fuel. The arrangement of several deoxygenators for a single fuel stream improves removal of dissolved oxygen and provides for scalability of the fuel system to meet application specific demands. The arrangement also provides for the preservation of partial syste m functionality in the event of the failure of one of the deoxygenator modules .
