Energy-saving method for gas combustion and burner thereof

Abstract

The present invention relates to a method and a device taking gas as fuel in industry, dining halls, power plants and the like, in particular to an energy-saving, high-efficiency and environment-friendly method and a device for gas combustion. The energy-saving method for gas combustion is characterized in that: the combustion method is that: 1. gas enters into a hearth for one time or times of compression and expansion; 2. air is introduced into the hearth and is mixed with the gas; 3. the gas is ignited, the volume of the gas and the volume of the air are rapidly expanded and compressed in the hearth, and the bonds of gas molecules are cracked; 4. the gas rotates in the hearth at a high speed, and is fully combusted in a stove body to emit heat; and 5. when the gas is combusted, the gas is preheated before entering into the hearth. The present invention further discloses a device for realizing the method. When the device is used in the said method, a series of oxidization and reduction reactions take place in all substances in the gas when the gas is continuously expanded and decomposed, and the gas is converted to extremely high heat to be emitted and is sufficiently combusted, so that the gas is combusted more sufficiently, and the energy is saved.

1 . An energy-saving method for gas combustion, comprising the following steps:
 1) gas enters into a hearth for one time or times of compression and expansion;   2) air is introduced into the hearth and is mixed with the gas;   3) the gas is ignited, the volume of the gas and the volume of the air are rapidly expanded and compressed in the hearth, and the bonds of gas molecules are cracked;   4) the gas rotates in the hearth at a high speed and is fully combusted in a stove body to emit heat; and   5) when the gas is combusted, the gas is preheated before entering into the hearth.   
     
     
         2 . A black-hole gas burner, comprising a safety valve ( 1 ), a stove body ( 2 ) and a siphoning and preheating gas drum ( 3 ), wherein the structural characteristic of the gas burner is as follows: a hearth ( 21 ) of the stove body ( 2 ) is internally provided with an expander ( 4 ); the siphoning and preheating gas drum ( 3 ) having a ring-shape is arranged surrounding the stove body ( 2 ) and is communicated with a induction trunk in the expander ( 4 ); a plate ( 5 ) with a circular hole ( 51 ) in the central position of the plate is arranged on the stove body ( 2 ). 
     
     
         3 . The black-hole gas burner according to  claim 2 , wherein the expander ( 4 ) is comprised of an internal expander ( 41 ) and an external expander ( 42 ); the internal/external expanders are cylindrical shaped, square shaped, polygon shaped or star shaped objects with a cavity ( 6 ); the side edge of each cavity ( 6 ) is provided with a plurality of through-holes ( 61 ); the internal expander ( 41 ) is sheathed with the external expander ( 42 ), so that a compression cavity ( 7 ) is formed therebetween. 
     
     
         4 . The black-hole gas burner according to  claim 2 , wherein the number of the internal expander ( 41 ) or the external expander ( 42 ) is one or more than two. 
     
     
         5 . The black-hole gas burner according to  claim 2 , wherein a connecting piece ( 8 ) is arranged between the internal expander ( 41 ) and the external expander ( 42 ). 
     
     
         6 . The black-hole gas burner according to  claim 2 , wherein an induction trunk ( 9 ) is arranged between the stove body ( 2 ) and the hearth ( 21 ), and the side wall of the hearth ( 21 ) is provided with a plurality of through-holes ( 211 ). 
     
     
         7 . The black-hole gas burner according to  claim 2 , wherein an eclectic igniter ( 10 ) is arranged on the hearth ( 21 ).
