Claims (1)

[Scope of claim for utility model registration] (1) A powerful gas combustor that includes an outer furnace combustion system and an inner furnace combustion system, and the outer furnace combustion system includes an outer furnace stand,
The inner furnace combustion system is composed of an outer furnace mixing tube and an outer furnace core, and the inner furnace combustion system is composed of an inner furnace stand, an inner furnace mixing tube, and an inner furnace core. Furthermore, the outer furnace stand has a substantially annular groove and its upper end surface is free. It has a regular stepped annular shape and blends with the lower end surface of the outer hearth, and the inner wall surface of the groove is provided with fixing blocks for fixing three outer hearth cores at equal intervals. A hole is provided in the outer furnace mixing tube, which is connected to the outer furnace mixing tube, and the outer furnace mixing tube has a slightly L shape, the upper end of which communicates with the bottom of the outer furnace stand, and the other end has a tapered groove. A circular gas inlet for injecting gas is installed at the center of the end face, fan-shaped air inlets for air intake are provided on both sides of the gas inlet, and the outer furnace core has a substantially annular shape. It has a lid-like shape and is installed at the upper end of the outer hearth.The area of the top end is made small to concentrate the firepower on the bottom of the pot, and an outer convex ring and an inner convex ring are installed on the lower end surface. The outer convex ring has radial grooves placed at equal intervals on the ring surface to allow gas to pass through, and there are several equally spaced grooves between the outer convex ring and the inner convex ring. The installed outer flame hole and middle flame hole are in contact with the inclined annular surface on the outer edge of the upper end of the outer furnace core and the inclined annular surface on the inner edge of the upper end of the outer furnace core, respectively, so that the mixed gas in the outer furnace stand is heated. The contact surface between the outer furnace core and the outer furnace stand is an outer convex annular surface provided with a groove, and the other corresponding parts form a gap of approximately the same width. This creates an outer ring pipe and a middle ring pipe, which allows the mixed gas in the outer furnace stand to be routed to the outer furnace core.
The inner furnace base is annular and is provided in the hollow part of the ring center of the outer furnace base, and the upper end surface thereof has a stepped annular surface.
There are several radial grooves equally spaced on the annular surface of the relatively low staircase, which is connected to the lower end surface of the inner furnace core, and which allows gas to pass through. is provided with fixing blocks that securely hold three inner furnace cores at equal intervals, the lower end of the inner furnace stand communicates with the inner furnace mixing tube to form a mixed gas passage, and one end of the inner furnace mixing tube communicates with the lower end of the annular body and has a tapered groove at the other end, a circular gas inlet is installed at the center of the end surface of the end, and fan-shaped air inlets are provided on both sides of the gas inlet. The speed of the gas injected into the tapered groove is used to suck in an appropriate amount of air, which is mixed by a mixing tube and sent to the inner furnace stand, where the inner furnace core takes on a mushroom-like shape and is heated to the outside. It is installed at the upper end of the hearth, and the shaft at the lower end is hollow and has several inner flame holes arranged at equal intervals, which communicate with the outer inclined ring surface of the upper end of the inner hearth, which allows for mixing inside the inner hearth. Air is sent to the furnace surface, and the contact surface between the inner furnace core and the inner furnace stand is the annular surface of the inner furnace core shaft end and the annular surface of the groove having a width radial groove, and the other corresponding parts are of approximately the same width. A gap is formed to form an inner ring conduit so that a part of the mixed gas in the inner furnace stand can be sent to the inner flame hole on the inner furnace core side, and the combination of these components allows the gas to When the gas is injected from the gas inlet at the end of each mixing tube, the velocity of the gas creates a pressure difference between the air pressure inside and outside the tapered groove, which causes an appropriate amount of air to be sucked in from the air inlet and mixed in the mixing tube. The majority of the mixed gas reaches the furnace surface through each flame hole and is ignited to form the main flame, while a small portion of the mixed gas passes through each annular pipe to the furnace side. A powerful gas furnace combustor characterized in that it reaches each flame hole and forms a seedling by ignition, and the seedling can ignite the gas in the floating part of each flame hole. (2) The above-mentioned strong gas combustor includes an outer furnace stand, an outer furnace mixing tube, and an outer furnace core, and the outer furnace stand has a substantially annular groove, and its upper end surface has an irregular stepped annular shape. Fixing blocks are provided at equal intervals on the inner wall surface of the groove to fix the three outer furnace cores, and a hole is provided at the bottom of the groove. The outer furnace mixing tube is connected to the outer furnace mixing tube, and the outer furnace mixing tube has a slightly L-shape, one end of which communicates with the bottom of the outer furnace stand, and the other end of which is provided with a tapered groove. A circular gas inlet for injecting gas is installed in the holder, and fan-shaped air inlets for air intake are provided on both sides of the gas inlet. It is installed at the top end, and the area of the top end is made small so that the firepower is concentrated on the bottom of the pot.The bottom end surface is equipped with an outer convex ring and an inner convex ring. The annular surface of the ring has radial grooves placed at equal intervals to allow gas to pass through, and between the outer convex ring and the inner convex ring there are several outer flame holes and inner flame holes placed at equal intervals. There are flame holes that communicate with the inclined annular surface on the outer edge of the upper end of the outer hearth and the inclined annular surface on the inner edge of the upper end of the outer hearth, respectively, so that when the mixed gas in the outer furnace stand is sent to the furnace surface, the main flame is emitted. The contact surface between the outer hearth core and the outer hearth stand is an outer convex annular surface provided with a groove, and the other corresponding parts form a gap of approximately the same width, forming an outer ring conduit and a middle ring conduit. This allows some of the mixed gas in the outer hearth to be sent to the outer hearth, outer flame hole, and middle flame hole, and the gas is injected from the gas inlet at the end of the mixing tube of the outer hearth. At this time, a pressure difference is created between the air pressure inside and outside the taper groove due to the velocity of the gas, and this causes an appropriate amount of air to be sucked in from the air inlet, mixed in the outer furnace mixing tube, sent to the outer furnace stand, and then A portion of the mixed gas reaches the furnace surface through each flame hole and is ignited to form the main flame, while a small portion of the mixed gas passes through each annular pipe to each flame hole on the furnace side and is ignited to form the main flame. This powerful gas furnace combustor is characterized in that a seedling is formed, and the seedling can ignite the gas in the floating part of each flame hole to achieve complete combustion.
