Abstract
The utility model provides a cubic air distribution combustion chamber, the utility model discloses characterized in that comprises urceolus, inner tube, shrouding, spout, nozzle interface, air inlet duct, wherein form the air distribution wind channel between urceolus and the inner tube, offered secondary distribution hole on the inner tube, air inlet duct and urceolus side is connected, and the nozzle interface is established at the urceolus top and is passed the urceolus entering and is connected with the inner tube, the spout is established in urceolus bottom, is connected the shrouding between urceolus and spout, be provided with dish -shaped cyclic annular aerofoil between inner tube and spout, it has the through -hole to fit with a contraceptive ring the equipartition at the cyclic annular aerofoil of dish. The beneficial effects of the utility model are that: reinforce the mixing effect of fuel and air, it is more abundant to burn, shorten flame wake flame length, overheavy firing, improvement combustion chamber temperature, improvement combustion efficiency.
Description
Technical field
This utility model belongs to burner's technical field of structures.
Background technology
In order to reduce the required heat that catches fire, rapid heated fuel oil, make fuel oil reach ignition temperature as early as possible, to realize catching fire as early as possible.Therefore the air capacity required for being burnt by fuel oil is divided into First air, secondary wind, tertiary air.Wind action is that fuel oil is sent into combustor, and initially catches fire required oxygen amount for fuel oil.Secondary wind, tertiary air, after fuel oil catches fire, feed at combustor back segment, and the oxygen amount needed for supply fuel oil subsequent combustion, to ensure that fuel oil burns completely.
Burner in the market, in staged air distribution structure, uses three air distribution blow-through flames, and flame is long, causes part burning to occur outside combustor, combustion intensity and efficiency is low, it is insufficient to burn.
Summary of the invention
The purpose of this utility model is precisely in order to overcome defect that above-mentioned prior art exists and provide a kind of three air distribution combustion rooms, its effect is reducing the length of flame, is forcing overwhelming majority burning to occur in combustor exactly, improve combustion intensity, thus improve chamber temperature, making burning more abundant, combustion efficiency is more preferable.
The purpose of this utility model is achieved by the following technical solution.
A kind of three air distribution combustion rooms, this utility model is characterised by, is made up of urceolus, inner core, shrouding, spout, nozzle interface, intake air way；Wherein form air distribution air channel between urceolus and inner core, inner core offers secondary wind distributing hole；Intake air way is connected with urceolus side, and nozzle interface is located at urceolus top and is connected with inner core through urceolus entrance；Spout is located at bottom urceolus, is connected shrouding between urceolus with spout；Being provided with dish-shaped ring-type aerofoil between inner core and spout, on dish-shaped ring-type aerofoil, ring is evenly equipped with through hole.
This utility model ring-type aerofoil of dish is set to cone, and its flared end is connected with inner core inner core, and necking end is connected with spout, and its tapering α is set to obtuse angle with the angle of combustor cylinder inwall.
Blower fan air feed enters from intake air way, and a part of wind enters combustor as first and second air distribution, and another part wind is entered combustor as three air distributions by the air distribution air channel between inner core, urceolus by through hole on dish-shaped ring-type aerofoil.
The beneficial effects of the utility model are:
1, strengthening fuel oil and the mixing effect of air, burn more abundant；
2, flame wake flame length is shortened, overheavy firing, raising chamber temperature, raising combustion efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Seeing Fig. 1, a kind of three air distribution combustion rooms 9, this utility model is characterised by, is made up of urceolus 1, inner core 2, shrouding 4, spout 5, nozzle interface 6, intake air way 7；Wherein form air distribution air channel 8 between urceolus 1 and inner core 2, inner core 2 offers secondary wind distributing hole 2.1；Intake air way 7 is connected with urceolus 1 side, and nozzle interface 6 is located at urceolus 1 top and is connected with inner core 2 through urceolus 1 entrance；Spout 5 is located at bottom urceolus 1, is connected shrouding 4 between urceolus 1 with spout 5；Being provided with dish-shaped ring-type aerofoil 3 between inner core 2 and spout 5, on dish-shaped ring-type aerofoil 3, ring is evenly equipped with through hole 3.1.
This utility model ring-type aerofoil 3 of dish is set to cone, and its flared end is connected with inner core inner core 2, and necking end is connected with spout 5, and its tapering α is set to obtuse angle with the angle of 9 inwalls of combustor.
Blower fan air feed enters from intake air way, and a part of wind enters combustor 9 as first and second air distribution, and another part wind is entered combustor 9 as three air distributions by the air distribution air channel between inner core, urceolus by through hole on dish-shaped ring-type aerofoil.
