7270539, Sep 18, 2007

Filed:

Oct 28, 2004

Appl. No.:

10/977203

Inventors:

Mark L. Sujata - Oak Park CA, US

Assignee:

Soil-Therm Equipment, Inc. - Agoura Hills CA

International Classification:

F23G 7/06
F23D 14/46

US Classification:

431 5, 431 8, 431190, 431353, 431181, 110238, 110346

Abstract:

A burner assembly for the destruction of noxious vapors and other waste streams includes an inner burner element in the form of a sudden expansion burner and an outer burner element that encircles the inner burner element and forms an annular passageway between the two elements. Waste vapors may be conducted directly into the flame of the inner burner element (direct inject) or routed through the annular passageway and preheated, for injection at the flame or beyond. The burner elements may include solid or perforated cones mounted on their exits to enhance mixing and injection of the streams. The burner assembly may be equipped with water injection nozzles for flash oxidation of contaminants in waste waters.

Abstract:

A burner assembly for the destruction of noxious vapors and other waste streams includes an inner burner element in the form of a sudden expansion burner and an outer burner element that encircles the inner burner element and forms an annular passageway between the two elements. Waste vapors may be conducted directly into the flame of the inner burner element (direct inject) or routed through the annular passageway and preheated, for injection at the flame or beyond. The burner elements may include solid or perforated cones mounted on their exits to enhance mixing and injection of the streams. The burner assembly may be configured as in inline duct burner. A wide range of contaminants may be processed because waste streams having primarily nonflammable or combustion inhibiting constituents may be processed.

Filed:

Jun 22, 1989

Appl. No.:

7/369880

Inventors:

Mark L. Sujata - Agoura Hills CA
Raymond E. Wieveg - Ventura CA
Robert Wills - Torrance CA

Assignee:

The Marquardt Company - Van Nuys CA

International Classification:

F23G 704

US Classification:

110346

Abstract:

The improved incinerator is a concentric elongated tubular array, with an outer closed tubular housing or shell, an annular tubular heat exchanger in the form of a bundle of spaced open ended tubes inside the housing and spaced inwardly therefrom to define an annular air passageway therebetween and front and rear spaces, and a tubular combustion chamber having an open front end and an open rear end. The front end thereof is necked down and in the form of a small diameter tubular inlet immediately downstream of the combustion zone in the combustion chamber. A fuel line, a fluidized waste material line and an ignition system pass through the inlet into the combustion zone, along with heated air to initiate and maintain the desired complete combustion of the waste material. The air is preheated by blowing it into the passageway and around and over the heat exchange tubes, before passing it into the combustion zone. The waste gases exit the housing through an exhaust stack at the front of the incinerator, which stack can be in heat exchange with the blower duct, in order to also heat the air and cool the exhaust gases.

International Classification:

US Classification:

110238

Abstract:

The method of incinerating hazardous materials and fluidizable wastes, such as liquids, gases, entrained solid particles, fumes and slurries, utilizes an incinerator in the form of a sudden expansion burner. The incinerator has a relatively small diameter cylindrical inlet pipe connected by a circular plate to a relatively larger diameter elongated cylindrical combustion chamber. A waste injection line passes into the incinerator adjacent the inlet pipe for transfer of incineratable waste therethrough and into the upstream end of the combustion chamber. Air inlets connected to a blower also terminate adjacent the inlet pipe for supplying air at a high flow rate to the combustion chamber. One or more fuel nozzles extend through the plate into the combustion chamber to provide an overstoichiometric concentration of fuel adjacent the plate. The fuel is ignited through an electrically powered, fuel supplied ignitor extending into the combustion chamber through the inlet pipe.
