Abstract
The invention discloses a sweating type cooling nozzle combustor. The sweating type cooling nozzle combustor is characterized by consisting of an inner cylinder, an outer cylinder, an upper sealing plate, a lower sealing plate and a small cylinder, wherein a space between the inner and outer cylinders is formed to an air way; an inner cavity of the inner cylinder is a combustion chamber; fuels enter the inner cylinder from the upper end of the inner cylinder; a fan inlet enters a combustion chamber through the upper parts of the inner and outer cylinder; the lower end of the inner cylinder is connected to the outer edge of an upper sealing plate; the inner edge of the upper sealing plate is connected with the small cylinder; the small cylinder is connected to the inner edge of a lower sealing plate; the outer edge of the lower sealing plate is connected with the outer cylinder; and small holes are uniformly distributed on the small cylinder. The sweating type cooling nozzle combustor has the beneficial effects of shrinking the flame, shortening the flame length, reducing the nozzle temperature and preventing the ablation.
Description
Technical field
The invention belongs to burner structure technical field.
Background technology
In order to ensure the intensity of burning and the abundant of burning, burning should be allowed to complete in combustion chamber so the burner outlet length of flame embodies the important indicator of burner combustion effect quality as far as possible.For reducing the length of flame, generally combustor exit is designed to reducing, and the very high meeting of combustor exit flue-gas temperature produces high temperature ablation to combustor exit structure, so must cool combustor exit.
In burner structure in the market, combustor exit due to lack cooling structure or cooling structure unreasonable, combustor exit is easily by high temperature ablation.
Summary of the invention
Object of the present invention is just in order to overcome the defect that above-mentioned prior art exists and the burner providing a kind of and can shrink flame, reduce the length of flame, reduce nozzle temperature, avoid the band sweating formula cooled nozzle of ablation.
The object of the invention is to realize by following technical solution.
A kind of sweating formula cooled nozzle burner, the present invention is characterised in that, be made up of inner core, urceolus, upper sealing plate, lower shrouding, little cylinder, wherein, outer jacket casing inner core, formation air channel, space between inner/outer tube, interior tube inner chamber is combustion chamber, and fuel enters inner core by inner core upper end, and fans entrance enters combustion chamber by inner/outer tube top; Inner core lower end connects upper sealing plate outer rim, and upper sealing plate inner edge connects little cylinder, little cylinder connects lower shrouding inner edge, and lower shrouding outer rim connects urceolus; Little cylinder is evenly equipped with aperture.
The invention has the beneficial effects as follows:
Can flame be shunk, reduce the length of flame;
Reduce nozzle temperature, avoid ablation.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
A kind of sweating formula cooled nozzle burner, it is characterized in that, be made up of inner core 1, urceolus 2, upper sealing plate 3, lower shrouding 4, little cylinder 5, wherein, urceolus 2 overlaps inner core 1, formation air channel, space between inner/outer tube, inner core 1 inner chamber is combustion chamber, and fuel enters inner core by inner core 1 upper end, and fan interface enters combustion chamber by inner/outer tube top; Inner core 1 lower end connects upper sealing plate 3 outer rim, and upper sealing plate 3 inner edge connects little cylinder 5, little cylinder 5 connects lower shrouding 4 inner edge, and lower shrouding 4 outer rim connects urceolus 2; Little cylinder 5 is evenly equipped with aperture 5.1.Blower fan provide wind enter air channel from fan interface, blowed to by combustion chamber wake flame out by the aperture on little cylinder, reach cool burner outlet object.
