Title:
COMBUSTION APPLIANCE FOR RAISING THE TEMPERATURE OF EXHAUST GAS
Document Type and Number:
WIPO Patent Application WO/2011/108273
Kind Code:
A1
Abstract:
Disclosed is a combustion appliance for raising the temperature of exhaust gas comprised of a fuel injection nozzle (7), electrode rods (ignition devices) (8, 9) and a double cylinder type flame stabiliser (10) disposed so as to encompass the surrounding area thereof; closed on the distal side by a torus-shaped blocking plate (13) disposed between an inner cylinder (11) and an outer cylinder (12) of the flame stabiliser, and connected to one end of a combustion air guide line (15) which guides combustion air (14) between the inner cylinder (11) and outer cylinder (12); with a plurality of combustion air flow holes (16) disposed at the proximal end of the outer cylinder (11), and a plurality of peripheral fins (17) at a different position farther towards the distal end of the circumference of the inner cylinder (11) therefrom which are formed by cutting and raising radially inwards so as to guide the combustion air (14) from a circumferential direction and provide a swirling flow inside the inner cylinder (11); and a plurality of end face fins (18) also formed on the blocking plate (13) by cutting and raising in the direction of fuel injection so as to discharge the combustion air (14) in a circumferential direction and provide a swirling flow around the flame (21).
