Injection type combustion nozzle

Abstract

The invention discloses a spray burner body, which comprises a spray cylinder body, a steady burning tablet and a reverse-inject generator. The reverse-inject generator is shaped as a reversing pan, which is provided with a plurality of air blast burning ports on side edge and is fixed and connected with a supporting sheet at lower section of the side edge; the supporting sheet is internally provided with a spray cylinder fixing hole enabling the spray cylinder body to extend into; a plurality of semicircle breaches are arranged around the spray cylinder fixing hole; the steady burning tablet is provided with a fixing hole enabling the spray cylinder to extend into in the middle and also is arranged with convex points around the fixing hole on the upper surface; the upper end of the spray cylinder body penetrates through the steady burning tablet and extends into the reverse-inject generator, lower end of which is connected with fuel pipelines. Stable flare sheet connected with the air blast burning port is positioned below the air blast burning port to form a stable flare chamber. During utilizing, the air blast burning port and the stable flare chamber burn symmetrically to form double layer flares with upper big and lower small; therefore, the invention is able to effectively prevent unstable flame and tempering.

Description

technical field [0001] The invention relates to a jet burner body for gaseous fuel. Background technique [0002] At present, there is a flame nozzle for cooking ranges of fuels such as artificial gas, natural gas, liquefied petroleum gas, and biogas, one end of which is connected with a gas mixing pipe, and the other end is provided with a flame nozzle. During use, due to the removal of the traditional static pressure chamber, the flow rate of the mixed gas is high, and the gas above the specified pressure in the laboratory is fully combusted with high efficiency, but the gas source and pressure are adjusted to carry out flame-off and tempering experiments. The technology is unqualified. In the actual application of gas cookers, due to the large change of gas pressure, there are indeed problems of flame separation and tempering, and it is difficult to ignite. effect, and often burn out the mixed gas pipeline and the furnace body, there are serious safety hazards, great har...

Problems solved by technology

During use, due to the removal of the traditional static pressure chamber, the flow rate of the mixed gas is high, and the gas above the specified pressure in the laboratory is fully combusted with high efficiency, but the gas source and pressure are adjusted to carry out flame-off and tempering experiments. The technology is unqualified. In the actual application of gas cookers, due to the large change of gas pressure, there are indeed problems of flame separation and tempering, and it is difficult to ignite. effect, and often burn out the gas mixing pipeline and burn out the furnace body, there are serious safety hazards, great harm and other defects. There is an urgent need for a new environmentally friendly, energy-saving and efficient burner to solve the problems existing in the prior art.
