Abstract
The invention relates to a rotary premixed gas burner of a pottery kiln. On a basis of the original structure of the premixed gas burner of the pottery kiln, a gas scatter is mounted above a gas nozzle in a premixing chamber to guide gas to be scattered toward the inner wall direction of the premixing chamber, an air pipeline with a straight hole is changed into a combustion-supporting air gyrator of a rotary wing type to drive combustion-supporting air to rotate and further rotatably crosscut and push the scattered gas so that the gas and the combustion-supporting air are furthest mixed, and the plane design of the outer cylindrical surface of a fixed screw cap of a combustion plate is changed into the design of an outer cylindrical surface flume so that the combustion-supporting air passing through a cooling duct rotatably moves to push the flames of a combustion chamber to rotate and form the saturated flames of a flame-guiding hole.
Description
Affiliated technical field:
The present invention relates to a kind of gas combustion apparatus of furnace, especially can play effect energy-conservation, that reduce discharging.
Background technology:
A kind of pre-mixing gas combustion burner of furnace use at present is made of housing, premixer, gas pipeline, air duct, combustion chamber, honeycomb combustion plate, gas nozzle, air duct.It allows combustion gas and air realize twice mixing before entering the combustion chamber, but because the defective in the design, make that the flame of combustion gas, air and combustion chamber all is the axis moving linearly along burner, combustion gas and Air mixing can not be fully, and the flame of combustion chamber can't enter in the kiln body after leading the even distribution of hole, flame hole wall again.Promptly do not reach the energy-conservation maximization of design original intention, flame can't effectively transmit temperature to the kiln wall by leading hole, flame hole wall simultaneously, makes Yao Qiang limit and kiln central authorities form the temperature difference, and product just has aberration, the defect rate height.
Summary of the invention:
In order to overcome the technological deficiency that the furnace pre-mixing gas combustion burner does not reach energy-conservation maximization and kiln body temperature difference, the invention provides a kind of rotary premixed gas burner of pottery kiln.This rotary premixed gas burner of pottery kiln not only can allow air that mixing is passed in combustion gas rotation crosscut in the premixer, realizes premixed truly, and having overcome flame simultaneously can't be by leading hole, flame hole wall effectively transmits technological deficiency from temperature to the kiln wall.
Technical scheme:
The technical scheme that the present invention is taked when solving its technical problem is: in the premixer, install the combustion gas scatterer additional in the gas nozzle top, guiding gas is to premixer's inwall direction scattering; Change the air duct of straight hole the combustion air circulator of rotary wind type into, force the combustion air rotation, the combustion gas of scattering is rotated crosscut passes; Change the periphery planar design of burner plate hold-doun nut the design of into periphery skewed slot, allow the combustion air by the cooling air channel rotatablely move, promote the flame rotation of combustion chamber, form the saturated flame of leading the flame hole.
The invention has the beneficial effects as follows: the combustion air of rotation is rotated the crosscut passing to the combustion gas of scattering, realizes the maximization of combustion gas and combustion air mixability; Distributor promotes the flame rotation, has satisfied the equally distributed specification requirement of temperature in the kiln body.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing:
Fig. 1 is a rotary premixed gas burner of pottery kiln section of structure of the present invention;
Fig. 2 is a furnace pre-mixing gas combustion burner section of structure.
Among the figure: (1), housing, (2), air duct, (3), gas pipeline, (4), combustion chamber, (5), gas nozzle, (6), combustion gas scatterer, (7), combustion air circulator, (8), premixer, (9), the honeycomb combustion plate, (10), distributor, (11), burner plate hold-doun nut, (12), lead flame hole, (13), air duct.
Specific embodiments:
From the embodiment of Fig. 2 as can be seen, the furnace pre-mixing gas combustion burner is made of housing (1), gas pipeline (3), air duct (2), combustion chamber (4), premixer (8), honeycomb combustion plate (9), gas nozzle (5), air duct (13), burner plate hold-doun nut (11).Its design concept is to allow combustion gas and combustion air after mix for the first time premixer (8), realizes mixing when honeycomb combustion plate (9) enters combustion chamber (4) again.But it all is the straight line design that is parallel to burner axis that its technological deficiency is all passages, the mixability of (8) does not reach maximization in the premixer for combustion gas and combustion air, especially the cylindrical planar design of burner plate hold-doun nut (11), after combustion air enters combustion chamber (4) with the path of straight line, when flame is passed, objectively form a cold wind circle at the inwall of leading flame hole (12), to flame with lead flame hole (12) inwall and cause to a certain degree isolation, influence temperature and transmit, cause the temperature difference in the kiln body and influence product quality to the kiln wall.
In the embodiment in figure 1, the present invention is installed combustion gas scatterer (6) additional in gas nozzle (5) top on the basis of the former structure of furnace pre-mixing gas combustion burner; The air duct (13) that changes straight hole is a rotary wind type combustion air circulator (7); The outer disk of burner plate hold-doun nut (11) is changed into the distributor (10) of cylindrical skewed slot.
Leave gas nozzle (5) when combustion gas, the dead ahead is subjected to stopping of combustion gas scatterer (6), and changing that the straight line boundling moves is 90 ° of wall scatterings in premixer (8) of turning back.During combustion air process combustion air circulator (7), because of being subjected to the guiding of rotary wind type fan blade, enter premixer (8) in rotary manner, the combustion gas that forms circle-shaped scattering is rotated crosscut passes, realize the maximization of combustion gas and combustion air mixability, satisfied the energy-conservation maximized design original intention of rotary premixed gas burner.
Show also that in the embodiment in figure 1 combustion air one tunnel enters premixer (8), another road enters combustion chamber (4) through the cooling air channel, in the cold wind protection that realizes burner, realizes that secondary is combustion-supporting and to the passing of flame.The present invention changes the cylindrical disk of burner plate hold-doun nut (11) into the distributor (10) of cylindrical skewed slot, during combustion air process skewed slot, be subjected to the restriction of skewed slot just to enter combustion chamber (4) in rotary manner, the rotation of promotion flame, form the saturated flame of leading the flame hole, satisfied the equally distributed specification requirement of temperature in the kiln body.
