Title: Apparatus and method for controlling a forced flow once-through steam generator
IPC: F22G5/00
Filed: 1958-02-03
Abstract: 831.175. Forced-flow steam boilers. SULZER FRERES S. A. Feb. 3, 1958 [Feb. 7, 1957], No. 3523/58. Class 123(2) In a forced-flow, once-through boiler which may operate at supercritical pressure, a pump 10 supplies feedwater through a regulator valve 22 to a header 20 whence it flows through and is evaporated in heating tubes 32 lining the walls of a furnace 24 and connected to an outlet header 34. From the outlet header steam flows through a superheater 40 and outlet pipe 44 to the point of use. To reduce the power requirements and pressure head of the feedwater pump and to ensure an adequate cooling flow of working fluid through the tubes 32 at low loads a pump 50 is provided to recycle working fluid from the header 34 to the header 20. In operation, the fuel supply to the furnace burners 26 and the setting of the feedwater regulator 22 are respectively controlled according to variations in steam pressure and steam flow by regulators 56, 60 receiving impulses from a pressure sensing device 55 and a steam flow indicating device 58. The amount of working fluid recirculated is controlled either by impulses from the flow indicator 58 or from a pressure difference indicator 66 which compares the pressures in the headers 20, 34. The minimum pressure drop in the tubes 32 required to maintain an adequate cooling flow therethrough is maintained throughout any selected steaming load range by either control method which superimposes the recirculating flow on the main flow as that minimum is reached and thereafter increases the amount recirculated as the load further decreases or decreases the amount if the load increases.. In modifications the recirculation rate is controlled according to variations in electrical loading of a generator driven by a turbine supplied by the boiler or the speed of the recirculating pump is varied inversely as the speed of the main feed pump.

Abstract: 420,950. Fluid - actuated valves. BLOMQVIST, C. J. V., 56, Fridhemsgatan, Stockholm. Feb. 5, 1934, No. 3749. [A Speci. fication was laid open to inspection under Sect. 91 of the Acts, Aug. 7, 1934.] [Class 135] Valves controlled by pilot or relay valves.- A valve device particularly adapted for use in flushing apparatus and of the kind controlled by an auxi. liary valve actuated by hand or by a float has the actuating chamber bounded by a flexible wall adapted to serve as the main valve member by engagement with a perforated wall separating the inlet and outlet chambers. In, the form shown in the Figure the flexible wall is in the form of a sleeve 11 engaging at its upper end with a member 13 having an inwardly curved part against which the sleeve bears when the valve is open. The member 13 is secured to a detachable cover 15 and is provided with passages 17, 18. 19 adjustably throttled by a screw 20, connecting the inlet 2 with the chamber inside the sleeve. The lower end of the sleeve is clamped between a perforated thimble attached to a flange 8 and a member 22 carrying the seat 24 for the auxiliary valve 25. Slidably mounted on the spindle 27 of the auxiliary valve is a shouldered member 28 normally held in the raised positions against the action of a spring 30, by a spring 35 bearing against a perforated bucket 34 in a spindle 33. On depressing the operating handle 44, a plunger 41 is moved against the action of a spring 42 into engagement with the member 28 thus tilting the auxiliary valve to exhaust the actuating chamber. The inlet pressure then presses the sleeve away from the per. forated thimble and water flows through chamber 6 to the outlet. The outflowing water depresses the bucket so removing the support beneath the member 28, which moves under the action of the spring 30 into engagement with a headed screw 31 on the valve spindle. In this position the plunger 41 passes over the shoulder 29 so that the valve cannot be held in the open position. In a modification the auxiliary valve is actuated by a hinged float. In this construction the member 13 is carried by a tubular member passing through the bottom of the perforated thimble. The lower end of the tubular member is fitted with a valve seat adapted to cooperate with a valve member slidably mounted on the tube.
