摘要： Systems and methods for providing override control for a feedwater pump recirculation valve are provided. According to one embodiment, a system may include a controller and a processor communicatively coupled to the controller. The processor may be configured to receive one or more measurements associated with pump motor power driving feedwater pump flow. The feedwater pump recirculation valve may be configured to maintain a predetermined minimum recirculation flow through the feedwater pump by regulating recirculation pump flow through a recirculation line. The processor may be also configured to calculate, based at least in part on the one or more measurements, the recirculation pump flow, and compare the recirculation pump flow to the predetermined minimum recirculation flow. Based at least in part on the comparing, the processor may selectively provide an override control signal to the feedwater pump recirculation valve to selectively modify the recirculation pump flow.

摘要： The present invention makes it possible to reduce the size of a vaporization system by eliminating the need for conduits in the vaporization system, without it being necessary to form a flow path in order for a supply rate controller to be mounted inside a vaporizer, and is formed by a vaporizer that vaporizes a liquid material; a supply rate controller that controls a supply rate of the liquid material to the vaporizer; and a manifold block inside which an internal flow path is formed, and that has a device mounting surface on which both the vaporizer and the supply rate controller are mounted, wherein, as a result of the vaporizer and the supply rate controller being mounted on the device mounting surface, they are connected together via the flow path.

摘要： A feedwater controller for a flash type water tube boiler wherein feedwater flow through steam generating coils heated by combustion gases is compensated and adjusted, in order to provide proper combustion heat input over a broad range of boiler operating pressures and feedwater temperatures. Flowing feedwater affects combustion heat input through predetermined variations in fuel and air input to the boiler's burner. As disclosed, the first embodiment utilizes temperature and pressure compensating gates in a cylindrical orifice containing a spherical flow control member. Fuel/air control of the generator is provided through movement of the flow control member due to the forces induced by flowing feedwater. In an alternate embodiment, utilizes a piston in the feedwater flow path having a slotted cylindrical metering orifice attached thereto. Internal of the cylindrical orifice is a cooperating temperature compensated helical flow control member. Feedwater flow adjustments over a wide range of feedwater temperature is provided.
