Abrégé

This document relates to combustion burners and associated methods of operation. In one aspect a burner is operated to produce harmonic resonance.

Classes IPC  ?

• F23C 15/00 - Appareils dans lesquels la combustion est pulsée et influencée par résonance acoustique dans une masse gazeuse
• F23D 14/02 - Brûleurs à gaz avec prémélangeurs, c.-à-d. dans lesquels le combustible gazeux est mélangé à l'air de combustion en amont de la zone de combustion
• F23D 14/32 - Brûleurs pour la combustion d'un gaz, p. ex. d'un gaz stocké sous pression à l'état liquide utilisant un mélange de combustible gazeux et d'oxygène pur ou d'air enrichi d'oxygène
• F23D 14/34 - Brûleurs spécialement conçus pour être utilisés avec des moyens comprimant le combustible gazeux ou l'air de combustion

Abrégé

A burner system comprises a main body having a fuel conveying passageway having in seriatim and in fluid communication one with the next, a fuel-receiving inlet, a main passageway, and a fuel-emitting outlet, and an air conveying passageway having in seriatim and in fluid communication one with the next, an air-receiving inlet, an intake air-flow chamber, at least one air-flow opening, turbulent air-flow chamber, and an air-emitting outlet. The air-emitting outlet and the fuel-emitting outlet are positioned and oriented to permit delivery of air and fuel, respectively, to a common destination for subsequent combustion. The ratio of the minimum cross-sectional area of the intake air-flow chamber to the minimum cross-sectional area of the turbulent air-flow chamber is between about 1:0.8 and 1:1.2.

Classes IPC  ?

• F23D 14/22 - Brûleurs à gaz sans prémélangeur, c.-à-d. dans lesquels le combustible gazeux est mélangé à l'air de combustion à l'arrivée dans la zone de combustion avec des conduits d'alimentation en air et en gaz séparés, p. ex. avec des conduits disposés parallèlement ou se croisant
• F23D 11/40 - MélangeursTêtes de brûleurs
• F23D 14/58 - Buses caractérisés par la forme ou la disposition de l'orifice ou des orifices des buses, p. ex. en couronne

Abrégé

A cooling jacket, heat transfer apparatus and heat recovery apparatus for use with a burner comprises a main body having a front end and a back end and defining a longitudinal axis extending between the front end and the back end. There is at least one air inlet and a mixing chamber. A fuel passageway has a fuel receiving inlet and a fuel emitting outlet for delivering fuel to the mixing chamber. A first air flow channel has an inlet in fluid communication with the at least one air inlet, and an outlet disposed adjacent the fuel emitting outlet, for delivering air to the mixing chamber. The main body defines a fluid receiving and retaining chamber. There is a fluid inlet in the main body to permit the ingress of fluid into the fluid receiving and retaining chamber of the main body, and a fluid outlet in the main body to permit the egress of fluid from the fluid receiving and retaining chamber of the main body. A plurality of fluid directing vanes are disposed in the fluid receiving and retaining chamber of the main body to define a fluid flow path from the fluid inlet to the fluid outlet.
