Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is the axis geodesic structure figure of combustor provided by the invention.
Wherein:
Combustion barrel 1, petrolift 2, cartridge 21, igniter 3, casing 4.
Specific embodiment
Core of the invention is to provide a kind of combustor, ignition success rate height, and can make fuel completely burned.
In order to make those skilled in the art more fully understand technical solution of the present invention, below in conjunction with attached drawing and specifically
Embodiment combustor provided by the invention is described in detail.
As shown in Figure 1, the structural schematic diagram of the combustor provided for the present invention.Combustor in the present invention, including burning
Cylinder 1, combustion barrel 1 is cylindrical, and turbine can be passed through air thereto.In the inner cavity of combustion barrel 1, two fuel are at least set
Nozzle, fuel nozzle are located at the air intake of combustion barrel 1, enter in combustion barrel 1 from the fuel sprayed in fuel nozzle, mixed with air
It closes.The airflow direction that fuel nozzle sprays the direction of fuel and enters combustion barrel 1 has certain angle, and angle is acute angle, combustion
Expect that the one-component of emission direction is identical as air motion direction.Each fuel nozzle has a set of independent fuel supply system
System, each fuel nozzle passes through cartridge 21 respectively and is connected to corresponding petrolift 2, by petrolift 2 to fuel nozzle
Middle pumping fuel.Fuel nozzle is fixedly installed in combustion barrel 1, and the angle of each fuel nozzle corresponds to each other setting, makes difference
Fuel in fuel nozzle can mutually cross.
Two or more fuel nozzles are accordingly also equipped with the igniter of identical quantity, each fuel spray of lighting a fire every time
Mouth is attempted to start, as long as there is a completion igniting at this time, other related fuel nozzles of the flame ejected ignite together.One
The probability that igniter can not ignite is higher, and the probability that two or more igniters can not ignite simultaneously will be greatly reduced,
To improve the success rate of igniting.Combustor enters normal operating conditions, the fuel energy in each fuel nozzle after lighting
Enough injections mutually cross, the fuel that a fuel nozzle sprays can not completely burned when utilizing, can be sprayed on another fuel nozzle,
It is lighted by the thermal-flame of another fuel nozzle, to realize that full combustion utilizes.Multiply flame crosses jointly, can make combustion barrel
Higher temperature is formed in 1, higher temperature can also promote burning complete.Under normal circumstances, as long as there is two groups of fuel nozzle phases
It mutually crosses, another is ignited by one of them, relative to the combustion system of one flame, can more efficiently utilize combustion
Material.
A preferred technical solution is provided in the present invention, that is, two fuel nozzles are set and petrolift 2, cartridge 21 are adopted
With copper pipe, petrolift 2 and cartridge 21 are exposed to outside, are able to bear high temperature in a certain range.
Further, it being also correspondingly arranged on detection electric eye in the present invention, a detection electric eye is respectively arranged in each fuel nozzle,
Detection electric eye is located at one end that fuel nozzle connects cartridge 21, for detect fuel nozzle whether normal ignition, and by signal
It transmits and feedback effect is to petrolift 2 and igniter 3, control the working condition of petrolift 2 and igniter 3.When loss of ignition or
Extinguish suddenly in operation, petrolift 2 locks automatically, and stopping continues to supply fuel；In ignition phase, if lighted a fire successfully, control
Igniter 3 processed stops igniting, and burned flame continues to ignite fuel.Two or more detection electric eyes can be more accurately
The working condition for measuring fuel nozzle, provides more accurate data-signal.
The utilization rate of fuel when in order to further increase burning, is also fixedly installed with burning web, burning web in combustion barrel 1
Positioned at the open end of fuel nozzle, fuel injection goes out to touch burning web, and burning web is by high temp fire in normal work
The heating of flame keeps very high temperature, and a high-temperature region is formed in combustion barrel 1.Under mutual ignition condition still not by
The part of fuel of full utilization can be ejected on burning web, heated and lighted again by the burning web of high temperature, to further increase combustion
Expect the degree of burning.Burning web may be provided at the mutual intersection of fuel, may also set up in closer to exit, by it is secondary ignite with
It ignites and separates three times.
Specifically, lasting high temperature can be born when burning web use, selects heat-resisting material, preferably may be configured as height
Warm titanium net.It certainly, can also be first with other materials with similar quality.
It needs to be fixed when combustor is installed, the bottom of casing 4 is provided with mounting flange, in order to finely tune installation
The waist hole of strip is arranged in the position of flange on mounting flange, and the part of 4 or more casing can be made sliding along the direction of waist hole
Dynamic, when installation, only needs that combustor is fixed on fire door by flange.
Specifically, the fuel nozzle selected in the present invention is high pressure atomizing nozzle, and eddy flow air distribution is also set up in combustion barrel 1
Steady flame device.
Temperature sensor and pressure sensor are also set up in combustion barrel 1, for providing feedback to petrolift 2, adjust fuel
The number of supply.Large and small fire is automatically adjusted according to the load variations of heat power equipment, while adjusting the supply of combustion air, is protected
Card burning is complete, it is reliable to run smoothly, while saving the energy.
During installation first by flange asbestos pad on combustor, combustion barrel 1 is protruded into burner hearth, position is right after adjusting
Mounting flange is fixed on furnace body by quasi- screwhole position.After the position of burner hearth is protruded into confirmation, bolt everywhere is locked, guarantees combustion
Burning machine firmly installs.
Combustor of the invention is ignited by the way that the opposite fuel nozzle mutual cooperation of multiple angles is arranged, on the one hand can
Improve igniting success rate, on the other hand also can mutually light a fire, make cannot clean-burning fuel completely burned, carry out secondary benefit
With.In addition, being additionally provided with burning web, a high-temperature region is formed in the case where not hindering normally to divulge information, if there are also not yet complete
The fuel of complete utilization, by can also be lighted utilization when this high-temperature region again, realization is lighted a fire three times.These structures can play
Combustion-supporting effect promotes fuel availability, avoids wasting, and saves cost.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, this hair
It is bright to be not intended to be limited to the embodiments shown herein, and be to fit to and the principles and novel features disclosed herein phase
