It sets in the side of main fiery ejector pipe, can guarantee that the combustion gas mixing effect of air cavity is mixed at center.
It is connected between furnace head base and main fiery ejector pipe by being pressurized sleeve, is pressurized the conical round tubular of sleeve, and booster set
The internal diameter of cylinder increases from main fiery ejector pipe toward furnace head base direction, and the burner of the structure can reinforce the injection energy of main fiery ejector pipe
Power, pressurization sleeve can make combustion gas carry out secondary booster, to improve use power and the efficiency of combustion of burner, energy-saving ring
It protects.
The top of the pressurization sleeve is equipped with inclination top margin, and the angle for tilting top margin and horizontal plane is α, and 35 °≤α≤
55 °, the pressurization sleeve of the angular range can make main fiery ejector pipe reach optimal secondary booster effect, promote the mixed of combustion gas
It closes, energy conservation and environmental protection.
The bottom of the pressurization sleeve is equipped with the sleeve plane being arranged with the central axis upright of furnace head base, sleeve plane with
The bottom surface of furnace head base concordantly connects, and installs convenient for the production of burner, the stability after guaranteeing burner installation.
The main fiery ejector pipe, furnace head base and pressurization sleeve are integral type connection, and structure is simple, convenient for production.
The beneficial effects of the utility model are:
A kind of burner for improving injection tube structure of the utility model, structure is simple, and the burner of the structure can be reinforced
It is main fire ejector pipe ejector capacity, pressurization sleeve can make combustion gas carry out secondary booster, thus improve burner using power with
And efficiency of combustion, energy conservation and environmental protection.
