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： Description of a system of a thermodynamic steam pump for water propulsion, its heating, disinfection and sterilization, or propulsion of other liquids, characterized by use of water steam pressure as the propelling media of a liquid mass directly, without intermediate equipment to convert the energy, which is composed of a pressure tank, an electric input valve, steam under pressure provided by an external source and means for introduction by gravity of the liquid mass to be impulsed, with electromechanical elements to control level and flow, including a heat exchanger where recycled steam is forced through a tube panel which over heats the liquid thus eliminating the existing microbes and bacteria or just taking advantage of said heat exchanger to pre-heat and fluidify heavy crude oils or other viscous liquids with no expense of additional energy. This same thermo-hydro-dynamic system installed in a surface vessel (ship) can act as propulsor of the same by the action and reaction principle. (Jet propulsion.) Also, said system in another version can compress gases in an ample range of pressures. Said system or machine or motor converts the thermal energy directly to mechanical (kinetic) energy without any intermediate intervention or cooperation or existence of metal-mechanical parts or pieces in movement, or consumption of electric power in said energy conversions.

摘要： A snap-over toggle linkage valve actuating mechanism for alternately opening and closing a gas inlet valve and a gas outlet valve, has a pair of spring preload arms pivotably mounted to a fixed mainframe within a sealed pressure vessel for pivoting about a first pivot axis. A first toggle link is pivoted at a first end to the mainframe about the pivot axis A. A second toggle link preferably a compression coil spring under precompression is pivoted at one end about a second pivot axis C parallel to the first pivot axis A on said pair of spring preload arms. The second end of the first toggle link is pivoted to a second end of the second toggle link for pivoting about a third axis B parallel to axes A and C. The second toggle link constantly applies a compressive force on the pivot connection between the first and second toggle links such that a float within the vessel as a result of rise and fall of the liquid pivots the spring preload arms toward a position of longitudinal alignment with the longitudinal axis of the spring preload arms with an increasing compressive force applied to the first toggle link to maintain the first toggle link stationary in one of two oblique, over-center positions with respect to a center line Y extending parallel to the longitudinal axis of the spring preload arms with the second toggle link pivoting about the axis B and being axially compressed until the first and second links move across the center line Y. At that time, both toggle links instantly snap over into oppositely oblique, over-counter positions. The compressive force of the second toggle line may be variably adjusted.

摘要： A system for converting heat to kinetic energy, the system characterized by a fluid driven motor responsive to an introduction of high pressure fluid for driving a selected power train, and a pressure generator for introducing the high pressure fluid to the motor. The pressure generator includes a plurality of boiler tubes for receiving low pressure fluid, a fire box for successively transferring heat to the boiler tubes, and a pressure equalizer for incrementally equalizing pressures within the boiler tubes, whereby an introduction of low pressure fluid, followed by an efficient conversion to a high pressure fluid, is facilitated within the system.

摘要： In an industrial plant having a boiler and water cooled equipment, the two water systems are linked by means of a heat reclamation vessel having connecting upper and lower chambers. Tap water (e.g., at 60.degree.-70.degree. F.), after being used to cool equipment such as vacuum pumps, which causes the water to heat to 90.degree.-105.degree. F., is continuously delivered to the lower chamber of the vesel, near the bottom, where the water may, for example, have a temperature of about 95.degree.-110.degree. F. Spent steam (e.g., at a temperature of about 230.degree.-280.degree. F.) is continuously released in the upper chamber, where it is sprayed with water withdrawn from near the bottom of the lower chamber. The steam condenses and the condensate collects in the pool in the lower chamber. The water in the upper zone of the pool is kept at a higher temperature due to the collection there of the steam condensate. That water, e.g., at a temperature of about 185.degree.-200.degree. F., is continuously drawn off and used as boiler feedwater.

摘要： A closed loop solar collector system includes a fluid receiver for collecting solar heat to vaporize a working fluid therein. A uniflow engine connected to the receiver, is powered by the vaporized fluid to power a water wheel. The engine includes a single piston acting directly upon a pair of normally closed intake valves projecting into the engine cylinder. Under low boiler pressure conditions, a spring loaded connecting rod having depending arms each engaging one of the intake valve rods when in a normally raised position coordinates simultaneous opening or closing of the valves with a detent mechanism, enabling the piston to operate in a nonexpanding state. At high boiler pressures, the connecting rod disengages from the intake valve by means of a transmission rod and follower acted upon by outwardly displaced weights provided on a flywheel powdered by the engine drive shaft so that the piston operates in the expanding state. Exhausted vaporized fluid discharged from the engine enters a condensor alternately connected in series with first and second holding tanks so that the receiver fills with water draining from one of the tanks while the other tank refills with water from the condensor. The alternating cycle is controlled by steam actuated valves in response to fluid levels inside the holding tanks. The tanks are mounted to feed water to the receiver under gravity and under pressure of vaporized fluid entering the tanks from the receiver.

摘要： A condensate recovery system wherein a condensate receiver is provided between a boiler and a feed water tank with condensate being introduced into the condensate receiver during a period when water is not being fed to the boiler and with water being fed into the boiler during a subsequent feeding period by pumping make-up water into the condensate receiver. The system is arranged so that equalizing the pressure of the condensate inlet port of the condensate receiver with that at the low temperature water outlet port of the condensate receiver allows condensate to flow by gravity and replace low temperature water therein, leaving the condensate receiver filled with water.
