A system and method to generate steam from a feed water stream does so in a liquid pool zone of a vessel as the stream comes into contact with a heating medium that is less volatile than the feed water stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the feed water stream is vaporized or partially vaporized, any solids or unvaporized water present in the feed water stream come out of the stream and move into the heating medium. These solids and the unvaporized water may be further removed from the heating medium in the pool or in the pump-around loop. The heat exchange surface does not contact the feed water to generate steam.

A system for processing saltwater or brackish water while recovering energy otherwise wasted in electricity generation by a natural gas generator or turbine. Heat in the generator exhaust is used to directly heat and process the water in the saltwater or brackish water into high quality steam, separating the majority of salt and contaminants from the water, and leaving potable water that can be permitted and released to the environment or sold for agricultural or industrial use such as oilfield activities. The system also captures and liquefies CO.sub.2 in the generator exhaust.

A CO.sub.2 power generation system includes a furnace to burn fuel, a turbine operated by a working fluid supplied thereto, the working fluid being heated by heat generated in the furnace, a recuperator exchanging heat with the working fluid passing through the turbine, a cooler to cool the working fluid passing through the recuperator, and a compressor to compress the working fluid passing through the cooler, wherein the working fluid passing through the compressor is circulated to the furnace, and the working fluid is supercritical CO.sub.2.

Embodiments of the present disclosure include a system, method, and apparatus comprising a large scale direct steam generator operating on an oxidant of air or enriched air configured to generate steam and combustion exhaust constituents. An exhaust constituent separation system and an energy recovery system to reclaim energy and improve the efficiency of the thermodynamic cycle. An optional CO2 separation system and Non Condensable Gas injection system may be included.

A sensor cleaning system for a vehicle is disclosed. In particular, the sensor cleaning system has anti-freezing and defrosting functions. The sensor cleaning system includes: an air tank configured to store compressed air; a heating element disposed in the air tank and configured to apply heat to the air tank; and a controller configured to operate the heating element when a preset condition is satisfied.

A system and method for accessing a gas main is provided. The system including a drip riser having an interior portion and a first quick-connect coupler, the first quick-connect coupler being fluidly coupled to the interior portion. A riser attachment device is provided having a second quick-connect coupler, an open end, and a valve disposed between the second quick-connect coupler and the open end. The second quick-connect coupler is configured to removably couple with the first quick-connect coupler. The first quick-connect coupler and second quick-connect coupler cooperate to fluidly couple the open end to the interior portion when the riser attachment device is coupled to the drip riser and the valve is opened.

A multiple application orifice steam trap apparatus of the present invention includes: an orifice steam trap that has an orifice hole and is connected to a live steam delivery pipe to prevent leakage of live steam and discharge only condensate water; a back pressure adjustment unit that is connected to the rear end of the orifice steam trap from which condensate water is discharged and adjusts back pressure of the orifice steam trap; and a meter that is disposed at any one of or both between the front of the back pressure adjustment unit and the orifice steam trap or at the rear of the back pressure adjustment unit and measures any one or both of temperature and pressure at any one or both of the front and rear of the back pressure adjustment unit.
