摘要: A method is disclosed for directing flow to a combustor embedded in a recuperator while shielding the recuperator from radiative heat transfer from the combustor. The radiation heat shield also serves as a structural component to center the combustor within the recuperator core cavity and to allow motion between the combustor and recuperator as temperatures vary. The disclosure is illustrated by the example a gas turbine engine comprising three turbomachinery spools, an intercooler, a recuperator and a combustor. Thermal efficiency of such an engine can be increased by raising the high pressure turbine inlet temperature. It is a specific goal of the present disclosure to reduce radiative heating of a recuperator by a combustor which is housed substantially inside the recuperator.

摘要: A cogenerating recuperated microturbine includes a recuperator, an air compressor and a combustor. The combustor burns a fuel along with the compressed air received from the recuperator to create products of combustion. A turbine generator operates in response to expansion of the products of combustion to generate electricity. The products of combustion then flow through the recuperator to preheat the compressed air. The products of combustion then flow out of the recuperator as an exhaust flow. A heat exchanger is movable into and out of the exhaust flow to selectively heat a fluid in the heat exchanger. The heat exchanger is actuated by a piston-cylinder type actuator that operates under the influence of compressed air selectively bled from the air compressor. The actuator may be a single-acting cylinder used in conjunction with a biasing spring, or may be a double-acting cylinder.

摘要: A solar receiver for conversion of solar radiation to thermal energy includes an enclosure defining a cavity and having an aperture for receiving an influx of concentrated solar radiation. A heat exchanger is received within the cavity for transferring heat out of the solar receiver. The heat exchanger comprises a plurality of heat exchange cells arranged in polygonal array within the cavity. Each heat exchange cell comprises an inlet, an outlet, and a heat exchange matrix interposed within a first volume defined between a first plate and a second plate spaced apart from the first plate. The inlet and outlet are in fluid communication with the first volume and the first plate, second plate, and heat exchange matrix are monolithically bonded as a unit. The first plate receives concentrated solar radiation and the heat exchange media defines a pathway for a fluid flowing from the inlet to the outlet between the first and second plates. The solar receiver further includes an inlet manifold in fluid communication with the inlet of each of the heat exchange cells and an outlet manifold in fluid communication with the outlet of the each of heat exchange cells. In a further aspect, a heat exchanger is provided.

摘要: A method of making a heat exchanger includes assembling one or more heat exchange cells. Each heat exchange cell is assembled by providing a top plate having an inlet aperture at one end thereof, an outlet aperture at the other end thereof, a first surface, a second surface and peripheral edges; and providing a bottom plate having an inlet aperture at one end thereof, an outlet aperture at the other end thereof, a first surface, a second surface and peripheral edges. The second surfaces of the top and bottom plates are juxtaposed with one another so that the inlet and outlet apertures of the plates are in substantial alignment with one another. The peripheral edges of the top and bottom plates are attached to form a high pressure chamber between the second surfaces of the plates. After being assembled, each individual heat exchange cell is tested before being attached to other heat exchange cells. The testing may include pressure testing of the heat exchange cell. The testing of each individual cell improves the quality and reliability of the fully assembled heat exchanger because each level of the heat exchanger has been pre-tested for defects (e.g. leaks) prior to further assembly steps.

摘要: A metallic-ceramic joint for a turbo-compressor spool is disclosed. A temperature-limited joint is moved from outside the bearings to between the bearings and near the center of the shaft joining the turbine and compressor. This placement can lower the temperature at and around the joint and reduces the sharp gradient (and associated thermal stress) naturally occurring between the turbine rotor and the cooler joint. The bearing closest to the compressor can be an oil bearing and the bearing closest to the turbine an air bearing. The bearing closest to the compressor and the bearing closest to the turbine can both be an oil bearing. The bearing closest to the compressor and the bearing closest to the turbine can both be an air bearing. Moving the metallic-ceramic joint between the bearings can provide sufficient isolation to enable the all-air bearing solution.
