20090092935 | Method for effective degassing of wicks - A process for degassing or presoaking wicks used in the manufacturing of candles. Spools of raw wick are placed in a wax bath. The door to the vacuum chamber is then closed and the pressure in the chamber is reduced. The reduction of the pressure forces wax into the wick fiber to ensure complete saturation of the wick. | 04-09-2009 |
20110003259 | Self Cleaning Burner System for Heaters and Fryers - A self-cleaning burner system incorporates an automatic clean cycle when the burner is started up. Cycles may be programmed for once-a-day cleaning cycle or for other desired interval. On start-up, the cycle routes a small amount of fuel to the burner for ignition inside the burner to clean the burner surfaces. The system incorporates an igniter for fast, routine, and safe ignition of the fuel. Thus, small amounts of debris that accumulate on a surface burner are automatically ignited when the burner is started, keeping the burner clean and operating at a high state of efficiency at all times. The self-cleaning burner system may be incorporated into a fryer or other heating appliance for reliable, efficient operation. | 01-06-2011 |
20110183275 | METHOD AND DEVICE FOR IGNITING AND OPERATING BURNERS WHEN GASIFYING CARBON-CONTAINING FUELS - With a method and a device for igniting and operating burners when gasifying a carbon-containing fuel using at least two gasification burners, start of the pressure gasification with short start times is made possible, at high pressures, without prior inertization of the gas space, while avoiding continuous fuel gas consumption in the pilot burner or ignition burner and also protecting stationary ignition burners against contamination by configuring one gasification burner as a start-up burner, which is ignited by at least one pilot burner using an electrical ignition device. A combustible gas mixture including a fuel gas and oxygen-containing gas is ignited by the pilot burner, in the start-up burner. After ignition of the start-up burner, at least one further gasification burner is ignited by this burner. The start-up burner is operated further as one of the gasification burners of the carbon-containing fuel via a change in medium. | 07-28-2011 |
20110183276 | DEVICE AND METHOD FOR THE DEGASSING OF DUSTS - An apparatus for the degassing of a dust from a synthesis gas produced by a gasification process, is disclosed. The apparatus comprises a main dust separator, a multi-purpose vessel, fluid for degassing and cooling and a storage facility for dust. The synthesis gas produced is conducted via a connecting pipe to a main dust separator, from which a de-dusted raw synthesis gas stream and a dust-like solid which also contains raw synthesis gas in the voids between the dust particles can be removed. The dust-like solid is directed into a multi-purpose vessel equipped with devices for reducing the pressure level so that a tail gas is obtained and a solid containing lower gas quantities in the void fraction remains. There is a device for transporting a solid into a gas exchange apparatus, the latter comprising a gas exchange tank, a dust separator and a feed device for exchange gas. It is possible to reduce the gas exchange tank to atmospheric pressure. The gas exchange apparatus has an outlet for a solid that has been at least partially liberated from raw synthesis gas, said apparatus having an upwards-oriented conveyor in which an upwards-directed gas and solids stream can be established. The conveyor has an open cross-section, a bottom clear opening and a top clear opening. A feed device for exchange gas which is directed into the bottom clear opening is positioned underneath the bottom end of the conveyor. The dust separator has a discharge device for a tail gas stream and a downwards-directed connection into the gas exchange tank for a solid liberated from raw synthesis gas. | 07-28-2011 |
20110256487 | DETONATION COMBUSTOR CLEANING DEVICE AND METHOD OF CLEANING A VESSEL WITH A DETONATION COMBUSTOR CLEANING DEVICE - A detonation device cleaning system includes a vessel having a main body including an outer surface and an inner surface that collectively define an interior chamber. A detonation combustor cleaning device is mounted to the vessel. The detonation combustor cleaning device includes at least one combustion chamber that defines a combustion flow path. The at least one combustion chamber includes a deflection member arranged along the combustion flow path. An ignition device is operatively connected to the at least one combustion chamber. The ignition device is selectively activated to ignite fuel within the at least one combustion chamber to produce a shockwave that moves in a first direction along the combustion flow path, is redirected back along the flow path within the at least one combustion chamber, and passes into the interior chamber to dislodge particles clinging to the inner surface of the vessel. | 10-20-2011 |
20120107751 | METHOD FOR SUPPRESSING ADHESION OF ASH AND DEVICE FOR SUPPRESSING ADHESION OF ASH IN BOILER - In order to stably operate a boiler using several kinds of solid fuels including depleted ash as fuels, adhesion of ash is suppressed. A calculator ( | 05-03-2012 |
20120308940 | NATURAL GAS PURGE BURNER AND ASSOCIATED SYSTEMS AND METHODS - Systems and methods for purging air and/or one or more inert gases from a flammable gas system, such as a natural gas pipeline, are described. In particular, this application discusses systems and methods for making and using a gas purge burner to purge air/inert gases from a flammable gas system. The gas purge burner includes a burner having a gas inlet and a gas escape vent. The burner also has a continuous ignition mechanism that includes an igniter (such as a pilot light and/or an electric igniter) that is disposed near the gas escape valve. The burner also has a gas outlet that can be disposed between the gas inlet and the gas escape vent and which is also configured to direct gases from the burner to a gas measurement device. The burner can be used to monitor the amount of flammable gas flowing into the burner and to continually ignite and burn off such gas until the stream of gas passing through the burner is substantially pure. Thus, the gas burner can allow a user to perform such tasks while being removed a safe distance from the actual burner, increasing the safety of the user during the pursing process. Other implementations are described. | 12-06-2012 |
20140287367 | Method for Operating a Combustor - A system for operating a combustor includes a sensor that measures an operating parameter associated with the combustor and generates a signal reflective of the operating parameter. The operating parameter is reflective of an ash deposition rate or an accumulated ash buildup. A controller receives the signal, compares the signal to a predetermined limit, and generates a control signal. A method for operating a combustor includes operating the combustor at a first power level that produces a first temperature that is less than or equal to a first predetermined temperature and creating a layer of ash. The method further includes measuring an operating parameter reflective of an ash deposition rate or an accumulated ash buildup, comparing the operating parameter to a limit, and operating the combustor at a second power level that produces a second temperature that is greater than or equal to the first predetermined temperature. | 09-25-2014 |
20150316255 | Air Nozzle Arrangement in a Fluidized Bed Boiler, Grate for a Fluidized Bed Boiler, and a Fluidized Bed Boiler - An air nozzle arrangement for a fluidized bed boiler, comprising an air feed pipe and an air nozzle which limit an air feed duct configured to supply air to the furnace of the fluidized bed boiler.
