Abstract
The invention discloses a double-cyclone combustor with a primary air distribution structure; and the double-cyclone combustor consists of a fan, an outer cylinder, an ignition mechanism, an inner cylinder, a cyclone piece, an oil nozzle and an oil way. The double-cyclone combustor is characterized in that cyclone piece blades are set as an inner cyclone blade and an outer cyclone blade; an air stabilizing cylinder penetrating through the inner cylinder along the axis of the inner cylinder is arranged at the top of the inner cylinder; the outer cyclone blade coats the air stabilizing cylinder, and is connected with the outer cylinder through support legs; the inner cyclone blade is arranged in the air stabilizing cylinder; a hole is formed in the center of the inner cyclone blade; and the oil nozzle is positioned rightly above the hole of the inner cyclone blade. The double-cyclone combustor has the following beneficial effects: the fuel and air mixing effect is intensified to improve the combustion efficiency; cyclone air currents are formed in a combustion chamber to form rotating flame so as to improve the combustion stability; and the carbon formation on the wall surface of the combustion chamber is prevented.
Description
Technical field
The invention belongs to burner's air distribution structure technical field.
Background technology
In order to reduce the required heat that catches fire, rapid heated fuel oil, makes fuel oil reach ignition temperature as early as possible, to realize catching fire as early as possible.Therefore the air capacity required for oil inflame is divided into First air, Secondary Air, tertiary air.A wind action sends fuel oil to combustion chamber, the required oxygen amount and confession fuel oil initially catches fire.Secondary Air, tertiary air are after fuel oil catches fire, and feed at combustion chamber back segment, the oxygen amount needed for fuel subsequent combustion, to ensure that fuel oil burns completely.
Burner is in the market in staged air distribution structure, and one time air distribution directly blows to combustion chamber or single cyclone type air distribution, fuel and air mixing effect is poor, flame is long, after-burning is serious, it is insufficient to burn, easily tie carbon, easy over-emitting black exhaust.
Summary of the invention
Object of the present invention provides a kind of to overcome defect that above-mentioned existing burner air distribution exists just and has double-cyclone, force blending, smooth combustion, against carbon deposition the burner of a cyclone formula air distribution structure.
The object of the invention is to realize by following technical solution.
The burner of a kind of cyclone formula air distribution structure, be made up of blower fan, urceolus, ignition mechanism, inner core, whirlwind sheet, atomizer and oil circuit, the present invention is characterised in that, whirlwind sheet blade is set to internal cyclone blade and external cyclone blade, be provided with at inner core top along inner core axial line also through the steady air duct of inner core, external cyclone blade is set in outside steady air duct, and is connected with urceolus by leg, and internal cyclone blade is arranged in steady air duct; Perforate is provided with at internal cyclone blade center; Atomizer is positioned at directly over the perforate of internal cyclone blade.
External cyclone blade of the present invention and internal cyclone blade are disposed on the same plane.
External cyclone blade of the present invention also can be set to not at grade with internal cyclone blade.
Internal cyclone blade of the present invention is identical with the rotation direction of external cyclone blade.
Internal cyclone blade of the present invention also can be contrary with the rotation direction of external cyclone blade.
The invention has the beneficial effects as follows:
1, the mixing effect of enhanced fuel and air, improves efficiency of combustion;
2, in combustion chamber, form swirling air-flow, form swirl flame, improve combustion stability;
3, prevent combustion chamber wall surface from tying carbon.
