Gasification burner using high-pressure swirled air

Abstract

Disclosed herein is a gasification burner using high-pressure swirled air. More particularly, the gasification burner using high-pressure swirled air is designed to enable partial cooling of a burner housing and to substantially prevent flames inside a combustion chamber from reaching an inner surface of the combustion chamber, resulting in an extension in the lifespan of the gasification burner. In the gasification burner comprising fuel feed pipe having a fuel injection nozzle, a combustion air feed pipe, an ignition plug, and a temperature sensor, which are located at one side of a combustion chamber defined in a burner housing, the gasification burner further comprises an air chamber unit, and a swirled air feeder unit. The air chamber unit is defined in an outer periphery of one end region of the housing where the fuel feed pipe and the combustion air feed pipe are mounted, and has a partition for providing the air chamber unit with a double-walled structure, defining an air feed channel. The swirled air feeder unit has a plurality of air-jet nozzles arranged along an inner periphery thereof near the fuel injection nozzle within the combustion chamber. The air-jet nozzles are obliquely disposed in a direction to communicate with the air feed channel.

1 . A gasification burner comprising a fuel feed pipe having a fuel injection nozzle, a combustion air feed pipe, an ignition plug, and a temperature sensor, which are located at one side of a combustion chamber defined in a burner housing, further comprising: 
 an air chamber unit defined inside an outer periphery of one end region of the housing where the fuel feed pipe and the combustion air feed pipe are mounted, the air chamber unit having a partition for providing the air chamber unit with a double-walled structure, defining an air feed channel; and    a swirled air feeder unit having a plurality of air-jet nozzles arranged along an inner periphery thereof around the fuel injection nozzle within the combustion chamber, the air-jet nozzles being obliquely disposed in a direction to communicate with the air feed channel.    
   
   
       2 . The burner as set forth in  claim 1 , wherein an inner surface of the combustion chamber is made of a refractory material.  
   
   
       3 . The burner as set forth in  claim 1 , wherein the combustion air feed pipe includes a swirled air spout portion formed at an inner surface of a distal end thereof, the swirled air spout portion having a plurality of swirl blades, which are obliquely arranged in the same direction as the air-jet nozzles.  
   
   
       4 . The burner as set forth in  claim 1 , further comprising: 
 an auxiliary combustion air feed pipe around the combustion air feed pipe.    
   
   
       5 . The burner as set forth in  claim 4 , wherein the auxiliary combustion air feed pipe includes a second swirled air spout portion formed at an inner surface of a distal end thereof, the swirled air spout portion having a plurality of swirl blades, which are obliquely arranged in the same direction as the air-jet nozzles.  
   
   
       6 . The burner as set forth in  claim 4 , further comprising: 
 an air passage tube for enabling communication between the air feed channel of the air chamber unit and the auxiliary combustion air feed pipe.    
   
   
       7 . The burner as set forth in  claim 1 , further comprising: 
 a transparent tube mounted in the housing near the combustion air feed pipe, and having a transparent member.    
   
   
       8 . The burner as set forth in  claim 1 , further comprising: 
 a projection unit mounted in the housing near the combustion air feed pipe, and having a transparent member, and a camera located at the outer side of the transparent member.    
   
   
       9 . The burner as set forth in  claim 5 , further comprising: 
 an air passage tube for enabling communication between the air feed channel of the air chamber unit and the auxiliary combustion air feed pipe.    
   
   
       10 . The burner as set forth in  claim 7 , further comprising: 
 a projection unit mounted in the housing near the combustion air feed pipe, and having a transparent member, and a camera located at the outer side of the transparent member.
