Furnace end of combustor

Abstract

The invention discloses a furnace end of a combustor, which comprises an upper cover, a lower bottom, a central mixing connecting pipe, a connecting pipe fixing disc and a mounting flange, wherein theupper cover covers the lower bottom; the upper cover is provided with a central fire ejector upper half part, a main fire ejector upper half part and a main fire upper half cover; the lower bottom isprovided with a central fire ejector lower half part, a main fire ejector lower half part and a main fire lower half cover; the central fire ejector upper half part and the central fire ejector lowerhalf part jointly form a central fire ejector; the main fire ejector upper half part and the main fire ejector lower half part jointly form a main fire ejector; a cavity defined by the main fire upper half cover and the main fire lower half cover is a main fire mixing cavity; the lower end of the center mixing connecting pipe penetrates through the main fire mixing cavity and then stretches intothe outlet end of the center fire ejector; and the upper end of the center mixing connecting pipe sequentially penetrates through a through hole in the main fire upper half cover, a center through hole of the connecting pipe fixing disc and a center through hole of the mounting flange from bottom to top and then stretches out to the position above the center through hole of the mounting flange. The space utilization rate is high, and the working reliability is high.

Description

technical field [0001] The invention relates to a stove head of a burner. Background technique [0002] At present, in the industry of gas cookers and integrated cookers, the traditional aircraft-type burners (or Siemens or cherry blossom burners) have been used for a large proportion because of their low price and good stability. Indispensable accessories for this industry application. However, the furnace head as a whole is basically cast iron or cast aluminum structure. The casting process of cast iron or aluminum alloy casting process, the second process of burning molten iron requires coal burning, sand core manufacturing, and cavity cleaning. Sand cleaning and other dusty, mass production A large production site is often required, and the production environment is not good. Long-term development is not conducive to the development of the industry and the protection of the ecological environment. [0003] In the early stage, there were stainless steel burners in the m...

However, the furnace head as a whole is basically cast iron or cast aluminum structure. The casting process of cast iron or aluminum alloy casting process, the second process of burning molten iron requires coal burning, sand core manufacturing, and cavity cleaning. Sand cleaning and other dusty, mass production A large production site is often required, and the production environment is not good. Long-term development is not conducive to the development of the industry and the protection of the ecological environment.

[0003] In the early stage, there were stainless steel burners in the market, but they were basically used for desktop gas stoves. However, due to the unreasonable use of base structures or materials, and with the upgrading of consumption, the proportion of desktop gas stoves in the entire market has been declining year by year. , so it has not been well promoted

[0004] In the early stage, there were also stainless steel burners for embedded stoves on the market, but the mai...
