    摘要: There is provided a combustor which produces high-temperature combustion gas and supplies the combustion gas to a driving apparatus, characterized in that a reducing portion is provided on a duct, an orifice plate is provided protruding from the parallel inner peripheral surface of the duct on the upstream side of the reducing portion, and the duct is disposed between a combustor inner tube and a combustor outlet pipe, thereby making the temperature of the combustion gas flowing from the combustor inner tube to the combustor outlet pipe substantially uniform.

    摘要: The flow-measuring device includes a restricting mechanism for throttling a fluid flow through a completely filled duct of rectangular cross section, whereby the flow rate is obtained from the differential pressure created by the pressures tapped from the duct sections upstream and downstream from the restriction. The restricting mechanism consists of a pair of flat orifice plates installed on the opposite inner walls of the duct and directed inwardly toward each other, with the inner edges of the plates being rectilinear and parallel to each other, equidistant from the opposite inner walls of the duct and within planes transverse to the direction of flow in the duct. The orifice plates are symmetrical to a plane extending along the centerline of the duct parallel to the inner walls.
