| 21 | Steam and water blending system for steam vaults | US714744 | 1968-03-20 | US3987130A | 1976-10-19 | Perry Arant |
| Apparatus for blending dry or slightly moist steam with water to produce wet steam of 20% to 70% moisture content by weight for treating logs or other objects in a closed steam treatment vat or vault. The apparatus includes a blender having a mixing chamber, to one end of which comparatively dry steam from a suitable source is supplied at constant pressure and flow rate through a pilot-operated pressure reducing main valve and a metering orifice. The blender also has a port through which water at a constant pressure and volume is supplied to the mixing chamber by a positive displacement pump maintained under a constant gravity head of water in an elevated supply tank. The outlet of the blender is connected to a back pressure regulator for controlling the outlet pressure of the blended mixture of water and steam to be supplied to the vault. The pilot valve is connected across the main steam valve and has a solenoid valve connected in the line supplying operating fluid to said main valve. The apparatus is controlled by a circuit including switches connected to the solenoid valve, and to an electric motor for driving the positive displacement water pump. The switches are connected in circuit with a sensing switch that is responsive to the temperature of the condensate within the vault, or to some other suitable criteria. The system functions automatically to blend water with relatively dry steam to continuously or intermittently supply wet steam having a substantially constant high moisture content at a substantially constant volume and pressure, as conditions in the vault require. | ||||||

| PROBLEM TO BE SOLVED: To provide a system, which combines a power generator and a desalination device, capable of producing freshwater without using a reverse osmosis membrane device.SOLUTION: In a system which combines a power generator (100) and a desalination device (200), the power generator (100) has: a circulation circuit (10) which serially connects a first heat exchanger (11), an expander (12), a second heat exchanger (13) with a space (13a) to produce steam (M) by evaporating seawater and a working medium pump (14); and a generator (15). The desalination device (200) has: a suction pump (21) to suction gas in the space (13a); control means (31) which drives the suction pump (21) so that pressure inside the space (13a) becomes saturated water vapor pressure; a condenser (22) which condenses the steam (M) introduced from the space (13a); and a freshwater tank (203) which stores freshwater (W) condensed by the condenser (22). | ||||||

| PURPOSE:To enable to decrease the energy loss during the pressure reduction by a structure wherein a bypass piping is provided with respect to a main steam piping led to the demand side and a steam turbine is arranged in the bypass piping so as to reduce the steam pressure just before the demand down to the pressure required at the demand side by passing a part of steam through the steam turbine. CONSTITUTION:A pressure indicating controller 21 controls valves 2 and 3 so as to obtain steam pressure required at a demand 22 side. However, because the pressure reduction by a pressure reducing valve 2 causes energy loss, the degrees of priority of the valves 2 and 3 are determined in their controlling so as to pass steam as large as possible through a bypass piping 18 in order to reduce the pressure of the steam at a steam turbine 4. In this case, the valve 2 may be fully open, if the steam pressure used at the demand 22 side permits. On the other hand, a flow indicating controller 19 measures the steam flow rate in a main steam pipe 17 and leads the steam exceeding the maximum steam flow rate passing through the pressure reducing valve 2 into an accumulator 5 so as to back-up in response to the increase of the required steam amount. Thus, the energy loss during the pressure reduction can be decreased and yet can be recovered as effective energy. | ||||||

| PROBLEM TO BE SOLVED: To implement accurate control in heat insulation and heating by use of low temperature saturated steam as a heating medium by reducing deviation of steam pressure. SOLUTION: Low temperature steam is introduced into a user 7 through a pressure-reducing section 2 having a vacuum pressure reducing valve 3 for reducing pressure of steam to or below an atmospheric pressure and a cooling section 4 for changing the pressure-reduced steam into saturated steam by cooling the pressure-reduced steam. The vacuum pressure-reducing valve 3 is given a set pressure regardless of the atmospheric pressure, and the vacuum pressure-reducing valve 3 is controlled to set temperature of the low pressure steam to a required saturation temperature by detecting and feeding back pressure of the low pressure steam and detecting temperature of the low pressure steam. The cooling section 4 has a spray nozzle, which jets cooling water through a filter, provided in a passage 61 for introducing the low pressure steam into a main body 6 of a cooling device, and the main body 6 of the cooling device is composed of a cylindrical tube having a passage through which the low pressure steam flows and multiply-perforated choke plates arranged in a series of multiple steps in the passage. | ||||||

| PURPOSE:To aim at improvement in the utilization factor of steam, by installing a pressure regulating valve and a steam turbine in a piping system, leading the steam produced out of a converter boiler, interposingly in parallel. CONSTITUTION:A pressure regulating valve 17 and a steam turbine 10 are installed in a piping system 7, which leads steam to be produced out of a converter boiler, interposingly in parallel. An arithmetic unit 30 calculates output of the steam turbine 10 on the basis of each signal out of pressure gauges 23 and 25 at both inlet and outlet sides of the steam turbine and a flow meter 24. When the output is larger than an allowable maximum output value, an opening of the pressure regulating valve 17 is made larger, and when it is smaller than an allowable minimum output value, the opening of the pressure regulating valve 17 is made larger as well, while inflow of the steam into the steam turbine 10 is intercepted. With this constitution, improvements in the utilization factor of steam energy is well promoted. | ||||||

| To ensure reliable production of superheated steam from saturated steam using simple means, a first subsidiary stream t1 of the saturated steam is throttled before being superheated by heat exchange with a second subsidiary stream t2 of saturated steam. A steam turbine (2), when supplied with this superheated reserve steam (SD) taken from a steam collecting drum (24) of its water-steam circulation (34), is exposed to a particularly low corrosion risk even during start up following a night stoppage. | ||||||

Ein Dampfumformverfahren, bei dem Frischdampf eines durch Temperatur TFD und Druck pFD gegebenen thermodynamischen Zustand 1 in Abdampf eines durch Temperatur TAD und Druck pAD gegebenen thermodynamischen Zustand 2 mittels eines Dampfumformventil mit Kühlwassereinspritzung überführt wird, dessen Frischdampfdurchlaß (Massenstrom ṁFD) und dessen Kühlwasserdurchsatz (Massenstrom ṁKW) mit dem einstellbaren Hub eines Ventilkörpers im Dampfumform- bzw. im Kühlwasserventil veränderbar sind, wobei das Dampfumformventil mit mindestens einem Regler zusammenwirkt, der zumindest eine von Temperatur und/oder Druck des Abdampfes (TAD; pAD) abhängige Regelgröße erzeugt, die zumindest auf den Kühlwasserdurchsatz über vom Regler an den Hilfsantrieb abgegebene Stellgröße einwirkt, soll so weitergebildet werden, daß ein sicherer Betrieb derartiger Ventile erreicht wird, wobei insbesondere auch eine Anpassung des Reglerverhaltens an fertigungs- bzw. verschleißbedingte Abweichungen des Ventils von seiner idealen Kennlinie möglich sein soll. Dazu wird der Hub des Ventilkörpers des Dampfumformventils abgenommen, sein Wert dem Rechner zugeführt, der daraus den das Dampfumformventil durchsetzenden Frischdampf-Massenstrom ṁFD und den dazu gehörenden Wärmestrom berechnet, ebenso der Hub des Ventilkörpers des Kühlwasserventils, aus dem dieser den das Kühlwasserventil durchsetzenden Kühlwasser-Massenstrom ṁKW berechnet und weiter aus den Massenströmen von Frischdampf und Kühlwasser unter Berücksichtigung der Wärmebilanz die zu erwartenden Werte für Temperatur T'AD und Druck p'AD, die dieser dann mit den den Meßwerten TAD und pAD vergelicht und daraus in an sich bekannter Weise die Stellgrößen für die Regelung der Kühlwassereinspritzung ableitet. |
