Abstract

The utility model provides a roller-hearth-kiln pressurization spray premixing burner core, comprising combustion nozzles, a combustion-supporting passage connecting plate, a closed-cover-type premixing chamber, atomized spraying nozzles, a fuel gas pipe, a connecting disc, a combustion-supporting air pipeline connecting port, a fuel gas pipeline connecting port and a combustion-supporting air pipe. The fuel gas and the combustion-supporting air are conveyed to the fuel gas pipe through pipelines simultaneously, and the fuel gas is pressurized by the combustion-supporting air, so that coarse mixing of the fuel gas and the combustion-supporting air is realized. The mixed air which is conveyed to the atomized spraying nozzles is subjected to primary fine mixing when being sprayed via a plurality of spraying holes. The mixed air is sprayed onto the inner wall of a premixing chamber and is rebounded, scattered and circulated, so that the mixed air enters a combustion chamber through the combustion nozzles and is combusted after secondary fine mixing is performed. The premixing degree of the fuel gas and the combustion-supporting air before being combusted is maximized in real sense, and the combustion efficiency of the fuel gas is maximized as well. Due to the effect of pressurization, the pressure of the mixed air reaching the combustion nozzles is kept high, and the flame range is very long.

Description

Roller kilns supercharging spraying premix burner core
Affiliated technical field:
The utility model relates to a kind of gas combustion apparatus of ceramic tile roller kilns, especially through after the technological means of supercharging spraying premix is implemented in combustion gas, can play effect energy-conservation, that reduce discharging.
Background technology:
A kind of pre-mixing gas combustion burner of roller kilns use at present is made up of premixer, Gas Pipe, combustion chamber, honeycomb combustion plate, burner plate hold-doun nut, gas nozzle, combustion air passage.It lets combustion gas and air before getting into the combustion chamber, realize twice mixing.But because the defective in the design makes to make combustion gas and combustion air subtract mistake to the thrust of flame combustion chamber by combustion gas, the air premix that reduces pressure in the premixer; Flame can't arrive kiln chamber central authorities; Make Yao Qiang limit and kiln central authorities form the temperature difference, product just has aberration, and defect rate is high.
Summary of the invention:
In order to overcome the technological deficiency that the roller kilns premix burner forms the temperature difference in the kiln body, the utility model provides a kind of roller kilns supercharging spraying premix burner core.Present technique not only can let the thick gas that mixes realize that high-pressure fog is smart mixed in the premixer, realizes combustion gas and combustion air premixed truly, has realized the overlength range of flame simultaneously.
The technical scheme of the utility model is: at first in the junction of Gas Pipe and gas pipeline, threeway is installed, connects the combustion air pipeline with combustion-supporting airduct, draw combustion air in Gas Pipe, when giving the combustion gas supercharging, realize slightly mixing; Opening part in Gas Pipe is provided with the atomized spray nozzle then; The atomized spray nozzle has spray-hole, and the inner chamber aperture of atomized spray nozzle is less than the inner chamber aperture of Gas Pipe, for mist is implemented secondary booster; Through the mist of spray-hole ejection, realize first smart mixing; At last,, the airtight bell-type of tubulose premixer is set, the mist bounce-back of guiding fuel injection, scattering, the smart mixing of circulation in the outside of Gas Pipe, atomized spray nozzle.
The utility model is installed in the burner shell, by burner noz(zle), and combustion air passage connecting plate, airtight bell-type premixer, the atomized spray nozzle, Gas Pipe, terminal pad, the combustion air pipeline connection port, the gas pipeline connector, combustion-supporting airduct constitutes.Burner noz(zle) is connected combustion air passage connecting plate combustion chamber one side, and the opposite side of combustion air passage connecting plate connects an end of airtight bell-type premixer, and the other end of airtight bell-type premixer is connected with terminal pad; One end of Gas Pipe connects the atomized spray nozzle, and the other end connects gas pipeline and combustion air pipeline respectively.
Gas Pipe is passed by the centre bore of terminal pad and is connected, and an end inboard at terminal pad places in the airtight bell-type premixer, and opening part connects the atomized spray nozzle, between the inwall of the periphery of Gas Pipe, atomized spray nozzle and airtight bell-type premixer spacing is arranged; Pass an end of terminal pad centre bore, connect threeway and, connect gas pipeline connector and combustion air pipeline connection port respectively, in order to connection gas pipeline and combustion air pipeline at two connectors in addition of threeway.
The atomized spray nozzle is made up of nozzle body and spray-hole, is the crown body of cylindricality, and there is thread the Guan Kou lower end, is connected with Gas Pipe, and cylindricality hat body wall has the transverse injection pore, and there is vertical injection pore on the Guan Ding plane.Laterally the distribution proportion of pore and vertical pore is confirmed by range requirement and kiln technical parameter.
The combustion air of the combustion gas of gas pipeline and combustion air pipeline through pipeline and threeway, is transported to Gas Pipe simultaneously, when combustion air pressurizes to combustion gas, has realized the thick mixing of combustion gas and combustion air; Be transported to the mist of atomized spray nozzle,, realize secondary booster because of the variation of caliber; Through the mist that some spray-holes eject, realize first smart mixing; Mist is ejected into the inwall of premixer, rebounds, scattering, shuttling movement, after realizing that secondary is smart and mixing, gets into combustion chambers burn through burner noz(zle).Premixed degree before combustion gas and the combustion air burning has reached maximization truly, and the combustion rate of combustion gas reaches maximization too.Because combustion air supercharging and secondary booster are introduced in combustion gas, it is powerful that the pressure when mist arrives burner noz(zle) keeps, flame range overlength.
Combustion air in the entering burner shell is outer wall through the premixer, and direction moves to the combustion chamber, gets into necessary process combustion air passage connecting plate before the combustion chamber.Because of the outer of combustion air passage connecting plate is skewed slot cooling air channel design, combustion air through the time, take away combustion air passage surface of connecting plate temperature on the one hand, play cooling protection effect to the premixer; Combustion air receives the guiding of skewed slot on the other hand, gets into the combustion chamber in rotary manner, and when promoting the flame rotation, the combustion gas that part is not reached burning is carried out combustion-supporting.The flame of rotation is being led flame hole formation saturated mode, for getting into the kiln hall again after the kiln wall transmission temperature.
The beneficial effect of the utility model is: not only let the thick gas high-pressure injection essence of mixing mix in the premixer, realize combustion gas and combustion air abundant premixed truly, realized the overlength range of flame simultaneously.
