20080264452 | Device and Method for Preventing the Drying of Fluid Products in a Dispensing Machine for Such Products | 10-30-2008 |
20090014036 | CLEARING PIPEWORK IN OIL REFINERIES AND OTHER PLANT HAVING EXTENSIVE PIPEWORK - A method for clearing pipework in an oil refinery includes the steps of: blowing, using a first, low velocity gas flow, pipe contents out of the pipework in such fashion that the contents are removed using gas overpressure, to leave a low contents residue; and substantially clearing the residue by a second, high velocity gas flow, the gas flows being such as not to give rise to a hazardous reaction such as fire or explosion. Apparatus for the same includes gas blowing means connectable to the pipework; valving adapted to throttle down an outlet of the pipework, said blowing means and valving being adapted to cooperate to effect both low velocity flow and high velocity flow through the pipework; and gas supply means to the blowing means supplying a gas that will not give rise to a hazardous reaction such as fire or explosion. | 01-15-2009 |
20090056762 | Method for Cleaning a Steam Generator - A method for cleaning a steam generator may include supplying water to the steam generator and boiling the water in the steam generator to separate and expel at least some deposits in the steam generator. | 03-05-2009 |
20130019903 | CLEANING SYSTEM AND METHOD FOR BEVERAGE APPLIANCE - The beverage appliance of the present invention includes a venturi having a steam inlet and a milk inlet. The steam inlet and milk inlet each include a solenoid valve configurable between an open state and a closed state. The solenoid valves are electrically coupled to a processor and are controllable through first and second switches. In operation, upon activation of the first switch, the solenoid valves are controlled to their open states to deliver milk and steam to the venturi to produce frothed milk. When a desired amount of frothed milk has been dispensed, the user deactivates the first switch and the processor controls only the milk inlet solenoid valve to its closed state. The steam inlet solenoid valve remains in its open state for a predetermined amount of time such that a burst of steam only is forced through the venturi and distribution lines to purge them of milk. | 01-24-2013 |
20130152973 | CONTROLLING COOLING FLOW IN A SOOTBLOWER BASED ON LANCE TUBE TEMPERATURE - A cleaning system and method for cleaning heat transfer surfaces in a boiler using a temperature measuring system for measuring and monitoring wall temperature of an annular wall of the tube of a lance of one or more sootblowers. Controlling a flow of steam or other fluid through the tube during the cooling portions of the strokes based on wall temperature measurements from the temperature measuring system. Infrared or thermocouple temperature measuring systems may be used. The steam or other fluid may be flowed at a default flowrate that may be substantially zero until the temperature measuring system indicates the wall temperature of the annular wall begins to exceed a predetermined temperature limit which may be the softening point of the annular wall. Then the steam or other fluid is flowed at a rate greater than the default flowrate. | 06-20-2013 |
20140174477 | METHOD AND APPARATUS FOR COMMISSIONING POWER PLANTS - An apparatus and method for commissioning steam turbine generator power plants to advance the cleanliness of the complete steam cycle by the conditioned discharge of steam to the plant surface condenser. | 06-26-2014 |
