A steam stop safety mechanism for a portable steam cleaner prevents discharge of steam at the cleaner nozzle when attaching and disconnecting attachments, even if the cleaner trigger is in a locked open position. The mechanism includes a steel pin that is displaced in an extended position against a shoulder in the nozzle to prevent pressurized steam from escaping the nozzle. Attachment couplings include a pin retractor plate with a central hub that pushes the pin away from the shoulder to allow ...

A steam distributor that uses a porous metal plate to replace the conventional screen plate of a steam shower for distributing steam to a moving web such as the web of a paper making machine. Steam showers using a steam distributor with this porous metal plate can deliver extremely uniform steam to the surface of a paper web. Profiling steam showers constructed by using an array of the steam distributors are able to deliver the best profiling results for various paper products. The porous metal ...

A steam generator (1) for steam baths, in particular steam cubicles, with a column-shaped housing (2) has an electrically heatable water bath (3) acted upon by air in operation, so that the air surrounding the housing (2) is sucked through a ventilator (4) into the housing (2) and recirculated through the housing (2) and through the water bath (3). The housing has a second inlet for insertion of a container holding additives.

In a steam turbine inlet which includes an annular steam strainer stationarily positioned therein for stopping the passage into the turbine of large metal particles, the improvement in the strainer which comprises a plurality of spaced through holes in a major portion of the strainer circumference, the through holes being of differing diameters, with holes of like diameter being positioned in longitudinally-extending, circumferential zones, holes of the largest diameter being disposed in zones w...

Drops of water in wet steam exiting a steam turbine are electrically charged. When exposed to a sufficiently strong electric field produced by suitably disposed electrodes (34,85), the electrically charged water drops disintegrate into numerous small droplets, which serve as nuclei for internal condensation. Supersaturation of the steam is decreased, thereby decreasing the amount of water in the vapor phase, the condenser pressure, and the turbine backpressure. Electrostatic forces acting upon t...

A steam generator for a steam bath for generating steam from hot water supplied thereto. The steam generator for a steam bath has a closed main part equipped with a hot-water supply port, an air inlet, a discharge port and a steam outlet. Hot water received from the hot-water supply port is distributed in the main part so as to contact with air coming through the air inlet,and the thus generated steam is discharged through the steam outlet. Warm water formed as a result of steam generation is di...

Steam iron having a sole plate with a steam chamber, and a sealed liquid reservoir. A drip valve supplies the steam chamber with liquid from the liquid reservoir. One or more one-way gas valves between the liquid reservoir and ambient air let air enter the reservoir in response to local negative pressures within the reservoir caused by movement of water within the reservoir, such as during reciprocal ironing motion. A pressure-equalizing passage is formed within a manually operable rod of the dr...
