Abstract: Systems and methods for regulating a bulk flame temperature in a dry low emission (DLE) engine are provided. According to one embodiment of the disclosure, a method may include measuring an exhaust gas temperature (EGT) and determining a target EGT. The target EGT is determined based at least in part on a compressor bleed air flow percentage and a combustor burning mode. The method may include calculating a bias based at least in part on the EGT and the target EGT and applying the bias to a bulk flame temperature schedule. The method may include regulating one or more staging valves and compressor bleeds of the DLE engine based at least in part on the bulk flame temperature schedule. The bulk flame temperature schedule is mapped to parameters of the staging valves and compressor bleeds to reduce nitric oxide, nitrogen dioxide, and carbon monoxide emissions.

Abstract: A system includes a fluid transfer system that has instrumentation configured to measure fuel properties; a fluidic buffer volume device located downstream of a fuel sensing point, wherein the fluidic buffer volume device is configured to provide a residence time for the fuel within the fluidic buffer volume device to enable a signal representative of the fuel properties to be communicated to enable adjustment of operating conditions of a fuel consuming system as the fuel is provided; and a controller programmed to receive properties of the fuel consuming system, receive the signal, receive properties of the fluidic buffer volume device, and generate a time-resolved volumetric grid that characterizes fuel transport properties of the fuel for different flow conditions and times based on the properties of the fuel consuming system, the fuel properties, and the properties of the fluidic buffer volume device.

Abstract: A system includes an inlet pipe configured to convey a fluid and a buffer volume configured to buffer the fluid. The buffer volume includes a smallest diameter tube having a smallest diameter, a first inlet end, and a first outlet end. The first inlet end is configured to receive the fluid from the inlet pipe. The buffer volume also includes an intermediate tube surrounding the smallest diameter tube having a first capped end and a second outlet end. The first capped end is positioned next to the outlet end of the smallest diameter tube. The buffer volume also includes a largest diameter tube surrounding the intermediate tube second capped end and a third outlet end. The second capped end is positioned next to the second outlet end of the intermediate tube. The system also includes an outlet pipe configured to convey the fluid from the buffer volume.

Abstract: A fuel routing system of a gas turbine engine includes a primary fuel circuit in communication with a fuel source and a fuel distribution manifold. Also included is a secondary fuel circuit extending from the primary fuel circuit to a plurality of fuel nozzles configured to direct fuel to a plurality of combustor chambers. Further included is a main fuel flow control valve disposed in the primary fuel circuit for restricting a fuel flow to the fuel distribution manifold upon removal of an electrical load operably coupled to the gas turbine engine. Yet further included is a plurality of check valves disposed between the secondary fuel circuit and the primary fuel circuit for restricting the fuel flow between the secondary fuel circuit and the primary fuel circuit.

Abstract: A method for evaluating opportunities in a sales funnel management system is disclosed. The method includes selecting one or more filters from one or more respective filter categories. The method further includes using the selected one or more filters to filter data provided to a data file, and providing actual opportunity data to the data file for each of one or more sales stages for each of one or more periods of time, based on the selected one or more filters. The method further includes displaying at least a portion of the provided actual opportunity data, and comparing the actual opportunity data to desired opportunity data to indicate whether a business entity is meeting its business plan.

Abstract: A method for developing a business plan for a business entity includes providing a value indicating a predicted amount of business entity sales for one or more products. The method further includes, based on the provided value, determining, for each of one or more sales sources, an expected amount of opportunities necessary to generate the predicted amount of business entity sales. The method additionally includes storing a respective indicator of the predicted amount of opportunities for each of the one or more sales sources, and using the one or more respective indicators to develop a business plan.
