20070202449 - Fuel injector, burner and method of injecting fuel: A primary flow of the burner air stream is slowed relatively to a secondary flow of the air stream. Fuel is injected at a lower rate into the primary flow, which generates a more stable flame, and fuel is injected at a higher rate into the secondary flow, which generates... Agent: Ogilvy Renault LLP

20070202450 - Catalytic burner for combustion of liquid fuels: Flameless catalytic burner systems made of zeolites that have a higher working temperature and greater flow rate than existing flameless catalytic burners have been developed. The burner systems comprise wicks that are capable of wicking low vapor pressure fuels.... Agent: Morgan Lewis & Bockius LLP

20070202451 - Gas radiation burner: A gas radiation burner for improving the efficiency of burning by promoting mixing of fuel gas and air is disclosed. The gas radiation burner includes a gas supply member for injecting gas, at least one mixing pipe for suctioning air along with the gas injected from the gas supply member... Agent: Birch Stewart Kolasch & Birch

20070202452 - Direct combustion steam generator: A method and apparatus for generating steam by heating water with a flame is provided. The water is introduced into a vortex sustaining container and flows through the container in a spiraling manner creating a liquid vortex with an open axial core. The flame effects heat transfer and is the... Agent: Buchanan, Ingersoll & Rooney PC

20070202453 - Premix burner: A premix burner for a heat generator has partial cone shells (5) which make up a vortex generator, and which encompass a conically widening vortex chamber (6) and mutually define tangential air inlet slots (7), and also with feeds for gaseous and/or liquid fuel, of which at least one is... Agent: Cermak Kenealy & Vaidya LLP

20070190469 - Methods and apparatus for preventing deposition of reaction products in process abatement reactors: In certain embodiments, methods, systems, and apparatus are provided for use in removing pollutants from a gas stream. The invention includes a thermal reaction unit formed from a plurality of stacked porous ceramic rings. The porous rings include perforations adapted to allow fluid to be flowed into the thermal reaction... Agent: Dugan & Dugan, PC

20070190470 - Method for igniting a burner: A method for igniting a fuel/oxidant mixture in an industrial furnace. At least one fuel supply conduit and at least one oxidant supply conduit is provided, each conduit having an opening that opens on a side of the burner head that faces the furnace interior space. Fuel and oxidant are... Agent: Alfred J Mangels

20070190472 - Burning wick structure: A burning wick structure includes an upper half portion and a lower half portion. The outer diameter of the upper half portion is larger than that of the lower half portion. The bottom surface of the lower half portion is provided with an insertion hole for being inserted by an... Agent: Hdsl

20070190471 - Fountain with an oil lamp: A fountain has a base, a body and an oil lamp. The base has a cavity receiving water. The body is mounted in the cavity and has a lamp seat a pump and a pipe. The pipe is connected to the pump and is mounted through the lamp seat. The... Agent: Rabin & Berdo, P.C.

20070190473 - Premixed duct burner: A fully premixed duct burner is provided that receives exhaust gas from a power generating device, such as a gas turbine or reciprocating engine. The burner may include a burner surface adapted to combust the mixture on or above the surface in blue-flame mode. Substantially all exhaust gas passes through... Agent: Dla Piper Rudnick Gray Cary Us, LLP

20070184394 - Production of cementitious ash products with reduced carbon emissions: The use of the cementitious ash in building products as total or partial replacement for Portland cement results in reduced carbon dioxide emissions that would otherwise result form the manufacture of Portland cement. In addition to avoided carbon dioxide emissions from calcining of limestone to make Portland cement and the... Agent: Harness, Dickey & Pierce, P.L.C

20070184395 - Apparatuses and methods for automatically extinguishing a flame: An apparatus for snuffing a candle or other element in a container. A base fits the container and includes shutter(s) for covering an opening. A shutter operator may include an arm preventing the shutter(s) from covering the opening when the arm is locked, and causing the shutter(s) to cover the... Agent: Nora M. Tocups
