Brown gas combustion apparatus and heating system using the same

Abstract

A brown gas combustion apparatus and heating system using the same is provided in which a brown gas generated from a brown gas generator flows into a water-tight flame arrester filled with hexane(C 6 H 14 ) of hydrocarbon systems so as to mix the brown gas with a small amount of hexane gas, to thereby delay the combustion speed and fundamentally prevent flash-back or back-fire. The brown gas combustion apparatus includes a heating unit which is directly heated by a burner and radiates heat. The heating system includes the combustion apparatus installed upright therein, and is configured in that the high temperature water molecules scattered from the combustion apparatus absorb the infrared ray radiated from an infrared ray radiation member within the combustion chamber, and oscillate in an ultra high temperature by self-heating. Thus-obtained high temperature heat is employed for heat exchange in a water pipe arranged in a boiler, and the hot water stored in a thermal storage tank is fed for heating or hot water supply. With such a combustion apparatus employed as a heat source for brown gas boilers, heaters, furnaces and hot blast heater, pollution-free clean energy can be obtained while preventing environmental contamination.

What is claimed is:  
     
         1 . A brown gas combustion apparatus using brown gas as a fuel, comprising: 
 a water-tight flame arrester which is communicated to a brown gas generator through a gas immersion tube provided with an open/shut-off valve and allows a small amount of hexane(C 6 H 14 ) at a vapor state to be mixed with a brown gas produced from said brown gas generator;    a burner communicated to said water-tight flame arrester through a gas supply tube provided with an open/shut-off valve and which burns the brown gas passed through said water-tight flame arrester; and    a heating unit to be heated by a flame of said burner.    
     
     
         2 . A brown gas combustion apparatus according to  claim 1 , wherein said heating unit comprises: 
 a hollow cylindrical second heating element having at an outer periphery thereof a plurality of radiating holes and which is mounted onto a base board;    a fiber-reinforce metal(FRM) surrounding an outer periphery of said second heating element;    a first heating element installed within said second heating element in such a manner that said first heating element is spaced apart from a bottom surface of said second heating element through a reciprocal cone-shaped heating portion arranged at a lower end of said first heating element; and    a cap arranged at a top of said first and second heating elements.    
     
     
         3 . A brown gas combustion apparatus according to  claim 1 , wherein said heating unit comprises: 
 a hollow and cylindrical second heating element having at an outer periphery thereof a plurality of upper holes and a lower hole and which is mounted onto said base board; and    a first heating element having a rectangular insertion portion and a circular protrusion protruded outwardly from an upper outer periphery of said insertion portion, said rectangular insertion portion and said circular protrusion being formed integrally, said first heating element having a plurality of side flame guide grooves formed from said insertion portion toward a lateral surface of a lower portion of said circular protrusion and a central flame guide hole perforated in vertical direction, said circular protrusion being mounted onto said second heating element with a predetermined spacing from a bottom surface of said second heating element.    
     
     
         4 . A heating system using brown gas as a fuel, comprising: 
 a water-tight flame arrester which is communicated to a brown gas generator through a gas immersion tube provided with an open/shut-off valve and allows a small amount of hexane(C 6 H 14 ) at a vapor state to be mixed with a brown gas produced from said brown gas generator;    a burner communicated to said water-tight flame arrester through a gas supply tube provided with an open/shut-off valve and which burns the brown gas passed through said water-tight flame arrester;    a heating unit to be heated by a flame of said burner;    a circulating combustion chamber formed of a far infrared radiation member surrounding said heating unit with a predetermined space interposed therebetween;    a water tube spirally surrounding an outer periphery of said circulating combustion chamber;    a thermal storage tank surrounding an outer periphery of said water tube with an air flow passage interposed therebetween, and which has an upper portion communicated to an exhaust pipe; and    an adiabatic member surrounding said thermal storage tank.    
     
     
         5 . A heating system according to  claim 4 , wherein said circulating combustion chamber has at a top portion thereof a peephole pipe communicated thereto for observing an interior of said circulating combustion chamber and preventing dewing in an early stage of operation of said heating system by opening a cap.  
     
     
         6 . A heating system according to one of  claim 4  or  claim 5 , wherein said heating unit comprises: 
 a hollow cylindrical second heating element having at an outer periphery thereof a plurality of radiating holes and which is mounted onto a base board;  
 a fiber-reinforce metal(FRM) surrounding an outer periphery of said second heating element;  
 a first heating element installed within said second heating element in such a manner that said first heating element is spaced apart from a bottom surface of said second heating element through a reciprocal cone-shaped heating portion arranged at a lower end of said first heating element; and  
 a cap arranged at a top of said first and second heating elements.  
 
     
     
         7 . A heating system according to one of  claim 4  or  claim 5 , wherein said heating unit comprises: 
 a hollow and cylindrical second heating element having at an outer periphery thereof a plurality of upper holes and a lower hole and which is mounted onto said base board; and  
 a first heating element having a rectangular insertion portion and a circular protrusion protruded outwardly from an upper outer periphery of said insertion portion, said rectangular insertion portion and said circular protrusion being formed integrally, said first heating element having a plurality of side flame guide grooves formed from said insertion portion toward a lateral surface of a lower portion of said circular protrusion and a central flame guide hole perforated in vertical direction, said circular protrusion being mounted onto said second heating element with a predetermined spacing from a bottom surface of said first heating element.
