Abstract
A pump uses the steam hammer effect to pump water from a reservoir into a control volume. Steam is injected into a water conduit extending between a liquid water reservoir and the control volume forms a liquid steam interface. Steam within the conduit condenses on the interface creating a region of partial vacuum. Water accelerates into the region of partial vacuum and is vented into the control volume, flow being controlled by a valve.
Claims26
A facility for generating electrical power, said facility comprising:
- an electrical generator;
- a steam turbine coupled to said electrical generator;
- a steam boiler adapted to provide steam to said steam turbine for operating said electrical generator;
- a liquid water reservoir;
- a water conduit providing fluid communication between said liquid water reservoir and said steam boiler;
- an exhaust valve positioned within said water conduit for controlling flow of said liquid water from said liquid water reservoir into said steam boiler;
- a steam conduit providing fluid communication from said steam boiler to said water conduit;
- a steam injector valve positioned in said steam conduit for controlling flow of said steam from said steam boiler into said water conduit;
- wherein
- opening said steam injector valve injects steam into said water conduit, said steam condensing on a water-steam interface thereby creating a partial vacuum within said water conduit, said liquid water from said water reservoir accelerating into said partial vacuum creating a pressure and momentum pulse within said water conduit, said exhaust valve opening permitting a burst of said liquid water to be injected into said steam boiler.
