摘要： A method for fabricating a three-dimensional turbine engine combustor liner model includes coupling at least a first member to a second member to form an assembly that has an inner surface. The assembly inner surface simulates an inner surface of the aircraft engine combustor liner. The first member is at least one of a pre-formed conical member and a pre-formed cylindrical member, and the second portion is at least one of a pre-formed conical member and a pre-formed cylindrical member. The method also includes coupling the assembly to a baseplate, and coupling a plurality of templates to the assembly.

摘要： For regulating engine exhaust and for environmental reasons, aircraft users are restricted from expelling engine fluids from engines onto airport ramps. All such fluid must be collected and subsequently burned or properly disposed of. The present invention installs witness drain valves in the drain lines between seal cavities and environmental collector tank. The witness drain valves have a small reservoir that will retain a known volume of fluid. As fluid passes from a leaking seal to the collector tank, a small sample is captured in the witness drain valve. Once the witness drain valve reservoir is full, the leaking fluid then flows on to a collector tank, which is also provided. During regular engine maintenance, technicians push on a spring loaded drain valve located on the witness drain valve reservoir. If fluid is detected, the seal is beginning to leak, and corrective maintenance may be scheduled while the leak rate is still within operational limits.

摘要： A gas turbine combustor improves the fuel distribution from a main fuel nozzle, suppressing fluctuations of internal pressure and elevation of inner tube metal temperature, and enhancing the combustion stability and durability of the combustor. The gas turbine combustor is a multi-nozzle type premixing combustor with a nozzle outer tube (7) for forming and injecting a premixed gas of main fuel and combustion air divided and disposed in plural sections around a cone (4) for forming a diffusion flame by reaction between pilot fuel and combustion air disposed in a center of a section of a combustor inner tube (1). Nozzle holes (5a) of a main fuel nozzle (5) are formed in three positions at equal intervals on the nozzle main body wall, and one of them is disposed at the outer periphery of the combustor inner tube (1) on a diametral line linking between the center of the combustor inner tube (1) and the center of the main fuel nozzle (5), whereby the fuel distribution to the outer periphery is decreased.

摘要： A combustion liner assembly for reducing nitric oxide (NOx) emissions is disclosed. This combustion liner utilizes an annular plenum outside the liner shell for the purpose of containing cooling air that has been heated and reintroducing it into the combustion process. The air plenum can be enlarged to increase the amount of cooling air contained within and still allow for installation of the liner assembly into the combustor by utilizing recesses that locally reduce the diameter of the air plenum to allow it to pass by liner mounting pegs within the combustor assembly.

摘要： A thermal energy retrieval system in which waste heat generated by an internal combustion engine is used to evaporate an organic working fluid in an evaporator. The evaporated working fluid is passed through a turbine to generate power which could be used to supplement the work done by the internal combustion engine. A unitary control valve is disposed between a feed pump and the evaporator to automatically regulate the flow of working fluid to the evaporator in accordance with the sensed temperature of the working fluid at its exit from the evaporator. This ensures the optimization of the thermodynamic efficiency of the system, which in turn leads to the provision of a more compact system useful with a road engine as an add-on.

摘要： A plurality of fuel nozzles X1 and X2 in combustor X are supplied with fuel gas from a fuel gas system and fuel oil from a fuel oil system, respectively. Gas turbine operation is performed with fuel being changed over to either gas or oil. Fuel oil distribution control system A controls oil flowing into a plurality of fuel pipings. When oil is changed over to gas, fuel oil purge system B is supplied with air of an appropriate temperature and pressure from purging air supply system C. This air flows into fuel oil pipings and nozzles X2 for purging residual oil therein. Fuel nozzle wash system D is supplied with water by-passing from a wash water tank for compressor washing. This water flows through nozzles X2 for washing thereof.

摘要： A heat rejection system is provided in a recirculating flow line, so that the steam production rate can be controlled from no steam production to maximum steam production for the gas turbine operating condition. For maximum steam production, the heat exchanger of the heat rejection system is bypassed so all the water is directed to the heat recovery unit (HRU). When no steam production is desired, all or a majority of the water is directed to the heat exchanger such that the heat absorbed in the HRU evaporator is equal to the heat rejected by the air cooled heat exchanger. Adjusting the flow split between these two limits allows the steam production rate to vary from no production to the maximum steam production capability corresponding to the gas turbine operating point.
摘要翻译：排气系统设置在再循环流动管线中，从而可以从燃气轮机运行状态的蒸汽产生到最大蒸汽产生来控制蒸汽产生率。为了最大化蒸汽生产，排热系统的热交换器被旁路，所有的水都被引导到热回收单元（HRU）。当不需要蒸汽生产时，所有或大部分水被引导到热交换器，使得在HRU蒸发器中吸收的热量等于由空气冷却的热交换器排出的热量。调整这两个限制之间的流量分配允许蒸汽生产率从对应于燃气轮机工作点的无生产到最大蒸汽产生能力变化。

摘要： A combustor includes outer and inner liners joined at one end to an annular dome. A swirl cup is mounted to the dome and includes a flare cone extending therethrough. The flare cone has an obtuse flare angle for discharging fuel in a wide spray from an outlet of the cone. A flared beat shield surrounds the cone, and extends in part aft from the cone outlet, and is offset in part forwardly from the cone outlet to define a radially outwardly facing step.
