Embodiment Construction

[0008] A kind of porcelain secondary mixing burner, the burner comprises a porcelain mouth core 1, the mouth core is sheathed with a tube 2, one end of the tube is connected with the furnace wall 3, a positioning plate 4 is provided in the tube, and the positioning plate fixes the mouth core in Between the positioning plate in the cylinder and the furnace wall (equivalent to the baffle effect). The other end of the barrel is provided with a nozzle regulator 5 and a compressed air supply pipe 6. A combustion-supporting air main pipe 7 is provided on the furnace wall.

[0009] This structure can form negative pressure and can conveniently adjust the amount of gas fed. Provide a basis for the implementation of dynamic timely adjustment.

[0010] According to the continuity law of fluid mechanics and Bernoulli's law, "when a fluid flows in a pipe, the pressure is lower at the place where the flow velocity is high, and the pressure at the place where the flow velocity is low is high" ...

Abstract

The invention discloses a ceramic secondary mixed combustion burner which comprises a burner core, wherein a cylinder is sleeved outside the burner core, one end of the cylinder is connected with a furnace wall, the cylinder is internally provided with a location disk which is used for fixing the burner core between the location disk and the furnace wall, the other end of the cylinder is provided with a nozzle regulator and a compressed air supply pipe, and the furnace wall is provided with a combustion air main pipe. The invention has the beneficial effects that the ceramic secondary mixed combustion burner can be used in severe environments with air source high temperature and low pressure as well as no clean, has a simple structure, and is not easy to block. Because the ceramic burner core is adopted, the ceramic secondary mixed combustion burner has long service life and small deformation and is easy to accurately regulate fuel feeding quantity.

Description

Technical field [0001] The invention relates to an industrial kiln appliance, in particular to a porcelain secondary mixing burner. Background technique [0002] At present, the burners of industrial kilns with large heat supply cannot adapt to the environment with low air pressure. Before forcing the combustion, the gas source is pressurized mechanically. When the gas source is a non-clean high-temperature gas and it is difficult to implement direct pressurization by mechanical methods, low gas source pressure becomes an insurmountable obstacle. As a result, a large number of industrial kilns have turned away the low-cost gas generators. Summary of the invention [0003] The purpose of the present invention is to design an industrial kiln burner that can adapt to high air source temperature, low pressure and poor cleanliness. [0004] The technical scheme of the present invention is: a porcelain secondary mixing burner, the burner includes a mouth core, the mouth core is sheathe...
