Abstract: Steam generation means in a closed system having a pressured steam boiler positioned within a closed heated feed water chamber. The steam generated in the boiler is used to drive a turbine and an associated electrical generator whose output augments the outside primary source of electrical power which is fed to one or more electrical resistance units located in the boiler. The exhaust steam from the turbine at reduced pressure is used to supply heat in any closed steam consuming device such as a space heating system. The condensate is returned to the feed water chamber where it is held in preheated condition ready to be pumped into the boiler to maintain the boiler water level. The efficiency of the system is substantially increased by having means for raising the temperature of the turbine and turbine housing thereby to lessen the temperature drop of the steam entering and leaving the turbine.

Abstract: A steam boiler for producing superheated steam directly in the boiler from saturated steam being generated therein includes a plurality of vertical sealed high pressure boiler water heating tubes, each provided with an electrical heating element and containing a limited quantity of water, mounted in a boiler water filled well in the bottom wall of the boiler. Energization of the heating element of each sealed tube produces high pressure saturated steam in the tube causing the tube to rise in temperature to generate saturated steam in the boiler from the water in the well. The tubes each have a vertical extent substantially greater than the controlled depth of water in the boiler. The saturated boiler steam is superheated by an elongated, sealed, vertical vessel mounted on the bottom wall of the boiler and extending upwardly into the boiler steam space above the upper ends of the heating tubes.

Abstract: A electric steam generating unit includes a housing having an upper end having a steam outlet and a lower end having a water inlet. An elongated tubular electric immersion heating element is vertically disposed in the housing in such a manner that an insulator space having a closed upper end is provided between the tubular element and housing. An elongated cylindrical rod-shaped electric immersion heating element is disposed coaxially within the tubular heating element and is so dimensioned that an elongated steam generating space of small volume subjected to the heat of both elements is formed therebetween.

Abstract: A steam turbine comprising a housing in which there are at least two rotors turning on a common axis in the same direction but at different speeds. The rotors are connected by gearing preferably located externally of the housing. In the preferred form, the faster rotating rotor is driven by steam from a first steam nozzle or nozzles. The adjacent slower rotating rotor is driven by steam from a second steam nozzle or nozzles. Specially arranged vanes on the slower rotor and fixed vanes on the housing enable the expanding steam to react between the first and second rotors and the second rotor and the housing to obtain the desired power output from the steam.In a modification, the second rotor has ports therethrough which extend diagonally backward and outward from the interior side of the second rotor to the exterior side so that some of the steam from the first steam nozzle if of higher pressure can pass through the diagonal ports to engage the fixed vanes on the housing.

Abstract: A governor for a steam operated engine by which the steam valve opening for any selected engine speed can be varied to accommodate different steam pressures, or conversely with a constant steam pressure, the steam valve opening may be varied to produce any selected engine speed.

Abstract: A steam turbine having side by side rotors within the turbine housing, one rotor fixed to the turbine shaft and the other rotor free to rotate on the turbine shaft. The fixed rotor has a single set of vanes, the freely rotatable rotor has two sets of vanes, one set being adjacent the vanes of the fixed rotor and the other set adjacent a fourth set of vanes integral with the housing. One steam nozzle delivers steam against the vanes on the fixed rotor and a second steam nozzle delivers steam against the set of vanes on the second rotor that are adjacent the fixed vanes on the housing. The steam pressure is controlled so that steam from the nozzles will drive the fixed rotor and shaft at a selected speed which may be faster or slower than the speed of the freely rotatable rotor. The freely rotatable rotor may include reversely directed apertures permitting steam from the first nozzle to flow outwardly to act against the fixed vanes on the housing.

Abstract: A governor for a steam operated engine by which the steam valve opening for any selected engine speed can be varied to accommodate different steam pressures, or conversely with a constant steam pressure, the steam value opening may be varied to produce any selected engine speed.

Abstract: The turbine rotor has about its periphery a steam track in the form of a groove. The groove is closed at its leading end by a small face and has walls which diverge in a helical pattern. The bottom and walls of the groove terminate in an outwardly sloping area which meets the closed leading end of the groove. Alternatively there may be a succession of grooves, each with a closed leading ends and diverging walls. Additionally the housing may include a stationary steam track closed at both ends with walls diverging in the opposite direction from the diverging walls of the groove in the rotor.

Abstract: Steam generation means utilizing first and second boilers, the first of which is a high pressure boiler located within or in very intimate heat transfer contact with the second boiler. The steam generated in the high pressure boiler is used to drive continuously or intermittently, a turbine and an associated electrical generator whose output activates electrical resistance units located in the boilers. These heating units supplement an external heat source to maintain steam pressure in the high pressure boiler. The exhaust steam from the turbine at reduced pressure is used to supply heat in any closed steam consuming device such as a space heating system. The condensate is returned to the second boiler which acts as a preheater for water to be pumped from said second boiler to said first boiler as needed.

Abstract: Supplementary means for heating liquid in a steam producing boiler comprising an electrical heating unit located in the boiler, the current for which is produced by an electric generator driven by a steam operated turbine. The turbine may utilize all or only part of the steam output of the boiler. Where the turbine uses substantially all of the steam, the generator driven by the turbine will have excess capacity to be used to drive a motor. Where the turbine uses only enough steam to drive a generator sized to meet the needs of the heating unit, the balance of the steam will ordinarily be used to drive some major prime mover or to supply heat to a heating system.
