Problems solved by technology

[0002] The round fire hole is a kind of fire hole commonly used in the design and production of gas burners. Since the round fire hole only has one air inlet and one air outlet, and the air outlet and the air inlet are on the same axis, Its internal passage is also straight. When using a circular fire hole, it is required to set the premixed gas chamber in the opposite direction of the flame outflow. When the opposite direction of the flame outflow does not meet the conditions for setting the premixed gas chamber, the circular fire hole It also cannot be used; when the process requires drilling holes toward the center of the circular combustion plate, the adjacent circular fire holes will also cross or even combine together with the increase in drilling depth, thus destroying the circular fire hole. The independent characteristics of the fire hole, even the result that the round fire hole is unusable

Embodiment 1

[0015] Embodiment 1: the combined use of combined fire hole and slit type combined fire hole, for directional outflow hole and stable flame outflow hole, gas introduction hole is set separately, as figure 2 As shown, the gas introduction hole 1, the directional outflow hole 2, the stable flame outflow hole 3, the combustion plate 4, the slit combined fire hole 5, the gas introduction hole 1 is a non-penetrating circular air channel processed longitudinally on the combustion plate 4 , the upper end is in a closed state, and the lower end opening communicates with the premixed gas chamber; the directional outflow hole 2 is a circular air channel that can be processed in any direction and at any inclination angle, intersects and communicates with the gas introduction hole 1, and its inlet is open to the gas introduction In the inside of the hole 1, the outlet is open in the combustion reaction zone; the stable flame outflow hole 3 is a circular or slit-shaped gas hole processed h...

Embodiment 2

[0016] Embodiment 2: The inclination angles of the directional outflow holes are different, such as image 3 As shown, the gas introduction hole 1, the directional outflow hole 2, the stable flame outflow hole 3, the combustion plate 4, the slit combined fire hole 5, the gas introduction hole 1 is a non-penetrating circular air channel processed longitudinally on the combustion plate 4 , the upper end is in a closed state, and the lower end opening communicates with the premixed gas chamber; the directional outflow hole 2 is a circular air channel that can be processed in any direction and at any inclination angle, intersects and communicates with the gas introduction hole 1, and its inlet is open to the gas introduction In the inside of the hole 1, the outlet is open in the combustion reaction zone; the stable flame outflow hole 3 is a circular or slit-shaped gas hole processed horizontally on the side wall of the gas introduction hole 1, located below the directional outflow ...

Embodiment 3

[0017] Embodiment 3: The orientation of the directional outflow hole is different, such as Figure 4 As shown, the gas introduction hole 1, the directional outflow hole 2, the stable flame outflow hole 3, the combustion plate 4, the slit combined fire hole 5, the gas introduction hole 1 is a non-penetrating circular air channel processed longitudinally on the combustion plate 4 , the upper end is in a closed state, and the lower end opening communicates with the premixed gas chamber; the directional outflow hole 2 is a circular air channel that can be processed in any direction and at any inclination angle, intersects and communicates with the gas introduction hole 1, and its inlet is open to the gas introduction In the inside of the hole 1, the outlet is open in the combustion reaction zone; the stable flame outflow hole 3 is a circular or slit-shaped gas hole processed horizontally on the side wall of the gas introduction hole 1, located below the directional outflow hole 2, ...

Abstract

The invention relates to a combined fire hole; a directed flowing-out hole and a stable flame flowing-out hole are intersected with a gas leading-in hole in a combustion board so as to form the combined fire hole; the direction and the inclined angle of the directed flowing-out hole can be changed freely on a condition that the gas leading-in hole is not changed; the independence and integrity of the combined fire hole cannot be damaged; flame states including special demands such as sector flame and the like can be acquired; and the combined fire hole can realize positive effect that large-area combustion flame can be generated by small-area fire distribution boards.
