Described burner mixes aerofoil by the circle that is threaded with the upper end of said Gas Pipe; The nozzle head that circular therewith mixed aerofoil is threaded is formed with the playpipe of fixedlying connected with the upper end of said air body; Described nozzle head is connected with said Gas Pipe; Described circle is mixed symmetrical through hole, one group of combustion air round tube hole and the one group of rectangular through hole of combustion air that is provided with the tapped through hole that is threaded with said Gas Pipe on the aerofoil from inside to outside successively, is connected with said high-tension ignition electrode; The rectangular through hole of described combustion air is evenly distributed on said circle and mixes on the outer round surface of aerofoil; The upper end of described nozzle head and high-tension ignition electrode all is arranged in the described playpipe
Described nozzle head is that the bottom is that cylindrical tube, end face are the composite unit structures of truncated cone-shaped end plate, and one group of combustion gas circular port evenly distributes on the conical outer surface of said truncated cone-shaped end plate.
Described playpipe is that the bottom is a pipe, and top is the compound tube body structure of conical pipe.
Described one group of combustion air round tube hole is the inclination circular hole, and described one group of rectangular through hole of combustion air is the rectangular through hole of inclination.
The operation principle of the utility model is:
Fuel gas gets in the Gas Pipe through fuel gas inlet; Air is got in the air body by air intake, is full of air in the air body, and two kinds of gases are respectively through behind the nozzle head and the various through holes on the mixed aerofoil on the body; Combustion air is being dispersed into tiny stream thigh later on through the various through holes that mix on the aerofoil; Rotary-jet and going out touches the combustible gas that is dispersed into tiny stream strand and oblique ejection equally through nozzle head and knows from experience fast and mix, and has strengthened the contact-making surface of fuel gas and combustion air; Strengthen mixed effect, shorten incorporation time; Gaseous mixture runs into the high-tension ignition electrode, burning rapidly, and flame spreads to the top; Above nozzle head, install playpipe additional, can effectively stop the tendency of flame combustion, flame is held together firmly, and effectively control the length and the burning position of flame, guarantee flame not from flame, continual and steady burning.
Can find out that from above operation principle the fuel gas caloric value determination apparatus of the utility model is compared with burner with traditional fuel gas caloric value determination apparatus with burner has advantage down:
1, because the burner of the utility model has adopted circular mixed aerofoil; And on the mixed aerofoil of circle, be provided with one group of combustion air round tube hole and one group of rectangular through hole of combustion air; Make combustion air be dispersed into tiny stream strand, and rotation sprayed, be convenient to the combustion gas rapid mixing and mix;
2, because the one group of combustion gas circular port that evenly distributes on the nozzle head of the utility model makes combustion gas be dispersed into tiny stream thigh, be convenient to the combustion air rapid mixing even;
3, because the playpipe top of the utility model is conical tube structure, global shape is a contraction mouth structure, stops the flame tendency effectively, prevents that it from leaving flame.
The utility model is simple in structure, can guarantee that fuel gas rapid mixing, fuel gas with low heat value are prone to light, the combustion process safety and stability.
