TECHNICAL FIELD
[0001] The utility model relates to a furnace technical field, especially a commercial fierce fire stove's furnace end structure and furnace structure. BACKGROUND
[0002] The traditional gas furnace end as the core component of the burner, its structure design directly influences the combustion efficiency and use performance. The existing furnace end usually adopts the modular assembly structure, is mainly composed of the furnace seat, the fire pipe, the fire cap and the fire cover. Its working principle is that: after the gas is sprayed from the nozzle of the furnace seat, the gas flows along the fire pipe from below to above, and the gas is premixed with air in the process. The mixed gas is sprayed through the top of the fire pipe, and the flame is dispersed through the shunt effect of the fire cap, and finally forms stable combustion on the surface of the fire cover.
[0003] In the current mainstream design, the fire cap is a key flame splitting component, and its main function is to break the straight spraying state of the gas to avoid the problem of insufficient combustion caused by concentrated gas injection.
[0004] However, the assembly mode of single fire pipe corresponding to single fire cap is generally adopted in the prior art, that is, one separate fire cap needs to be installed at the top end of each independent fire pipe. Although this design can meet the basic flame splitting demand, it has the following inherent defects: 1) redundant parts problem: for a multi-hole furnace end (such as 12-24 fire pipes distributed in a ring shape), the same number of fire caps need to be matched, resulting in a significant increase in the total number of parts; 2) high production cost: the fire cap usually adopts precision casting or machining process, and although the cost of a single fire cap is low, the cumulative cost is significantly increased when mass production; 3) low assembly efficiency: each fire cap needs to be positioned and installed separately, which increases the time and labor cost in the automatic production line, and manual assembly is more likely to cause quality problems such as missing and misassembling.
