Abstract
The invention discloses a pressurization spraying premix burner core for a roller kiln. The pressurization spraying premix burner core comprises combustion nozzles, a combustion-supporting passage connection plate, a closed cover premix chamber, atomized spray nozzles, a fuel gas pipe, a connection disk, a combustion-supporting air pipeline connection port, a fuel gas pipeline connection port and a combustion-supporting air pipe. The fuel gas and the combustion-supporting air are conveyed to the fuel gas pipe through the pipelines simultaneously, and the fuel gas is pressurized by the combustion-supporting air, so that the coarse mixing of the fuel gas and the combustion-supporting air is realized; the mixed air which is conveyed to the atomized spray nozzles is subjected to primary fine mixing when being sprayed by a plurality of jet holes; and the mixed air is sprayed into the inner wall of a premixer 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 realized. The premix degree of the fuel gas and the combustion-supporting air before combustion is maximized in real sense, and the combustion efficiency of the fuel gas is maximized. Due to the effect of pressurization, the pressure of the mixed air reaching the combustion nozzles keeps high, and the flame range is very large.
Description
Affiliated technical field:
The present invention relates to a kind of gas combustion apparatus of ceramic tile roller kilns, especially by after the technological means of pressurization spray 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 at present roller kilns use is made of premixer, Gas Pipe, combustion chamber, honeycomb combustion plate, burner plate hold-doun nut, gas nozzle, combustion air passage.It allows combustion gas and air realize twice mixing before entering the combustion chamber.But because the defective in the design, the premix so that combustion gas, air are reduced pressure in the premixer is so that combustion gas and combustion air subtract mistake to the thrust of flame combustion chamber, 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:
Form the technological deficiency of the temperature difference in the kiln body in order to overcome the roller kilns premix burner, the invention provides a kind of roller-hearth-kiln pressurization spray premixing burner core.Present technique not only can allow in the premixer thick mixed gas realize that high-pressure fog is smart mixed, realizes combustion gas and combustion air premixed truly, has realized simultaneously the overlength range of flame.
Technical scheme of the present invention 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; Then the opening part in Gas Pipe arranges the atomized spray nozzle, 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 mixed; At last, in the outside of Gas Pipe, atomized spray nozzle, the airtight bell-type of tubulose premixer is set, the mist bounce-back of guiding fuel injection, scattering, the smart mixing of circulation.
The present invention 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 consists of.Burner noz(zle) is connected to 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 respectively gas pipeline and combustion air pipeline.
Gas Pipe is passed by the centre bore of terminal pad and is connected, and the end in the terminal pad inboard 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, connecting tee and in addition two connectors of threeway connects respectively gas pipeline connector and combustion air pipeline connection port, in order to connect gas pipeline and combustion air pipeline.
The atomized spray nozzle is made 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.The distribution proportion of transverse air hole and vertical pore is determined by range requirement and kiln technical parameter.
The combustion air of the combustion gas of gas pipeline and combustion air pipeline by 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, because of the variation of caliber, realize secondary booster; Through the mist that some spray-holes eject, realize first smart mixed; Mist is ejected into the inwall of premixer, rebounds, scattering, shuttling movement, realize that secondary fine mixes after, enter 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.
Enter the interior combustion air of burner shell through premixer's outer wall, move to the combustion chamber direction, enter necessary process combustion air passage connecting plate before the combustion chamber.Because the outer of combustion air passage connecting plate is skewed slot cooling Duct design, combustion air by the time, take away on the one hand the surface temperature of combustion air passage connecting plate, play the cooling protection effect to the premixer; Combustion air is subjected to the guiding of skewed slot on the other hand, enters in rotary manner the combustion chamber, 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 entering Yao Tang after the kiln wall transmission temperature again.
The invention has the beneficial effects as follows: not only allow thick mixed gas high pressure spray ejaculation mixed in the premixer, realize combustion gas and combustion air abundant premixed truly, realized simultaneously the overlength range of flame.
