Advantageous effect
Compared with prior art, the advantages of premixed burner of the invention, is：
1, air is after entering air bin, and into being oriented in air duct and to Combustor Flows, the air that moves at this time can be
It is oriented in air duct and generates negative pressure, to which the combustion gas in gas chamber is oriented to air duct from the through-hole sucking being oriented on air duct, realize
The mixing of air and combustion gas increases the incorporation time of air and combustion gas moreover, because being oriented to air duct has certain length, mixes
More fully, to make the burning of mixed gas in the combustion chamber more abundant, energy transformation ratio higher has reached energy saving, noise reduction
Purpose；Since air and combustion gas just mix in guiding air duct, and the two is just sufficiently mixed when reaching combustion chamber substantially, is avoided
It allows the sufficient gaseous mixture of mixing to begin to burn in guiding air duct because air duct cup temperature is excessively high, extends the service life of burner；
2, the guiding wind due to the horizontal distance of guiding its output end of air duct of top to the combustion chamber center than lower section
The long 10-15mm of horizontal distance at road its output end to combustion chamber center is oriented to the combustion gas that air duct exports to allow from upper and lower two
In burning, can be mutually staggered longitudinally, and the air duct cup sidewall of conical surface shape can effectively avoid flame temperature most between the two
High flame envelope had both reduced the bulk temperature of air duct cup, in turn avoided gaseous mixture before entering combustion chamber because being oriented to wind duct temperature
Excessively high and premature combustion, improves efficiency of combustion, substantially extends the service life of burner；
3, the air that wind-guiding basin can allow into outside air bin first up flows to burner near top, since burner top exists
Temperature is higher when work, and the air being moved near it can be thermally formed hot wind, and the air after heating is upper around wind-guiding basin
Edge move still further below and enter each guiding air duct, the mixing velocity and the uniformity of combustion gas and air can be promoted, be conducive into
One step improves efficiency of combustion；
4, it is oriented to air hose mutually to fasten by the strip groove on two cylinder Flanges, the guiding air hose of formation
Length is enough, can play guiding role to entering the air of air duct cup inside by it, prevent the air-flow in the cup of air duct because being formed
Sinuous flow and be unevenly distributed, simple in structure, materials'use amount is few, cost with respect to existing product reduce 30%-40%；
5, due to being separate structure between two neighboring Flange, if gap, portion cannot be fully sealed and be formed
Divide air that can enter air duct cup inside by the gap, so as to cause there is sinuous flow in the cup of air duct；And Flange is fully sealed
Between its cost of gap it is higher；And can be blocked from the air leaked between Flange by the wind blocking cylinder of guide cup, it avoids out
Existing sinuous flow, and cost is very low.
