Wherein:
Combustion barrel 1, petrolift 2, cartridge 21, igniter 3, casing 4.
Detailed description of the invention
Core of the present invention is to provide a kind of combustor, and ignition success rate is high, and can make complete combustion of fuel.
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing and concrete embodiment, combustor provided by the invention is described in detail.
As shown in Figure 1, the structural representation of the combustor provided for the present invention.Combustor in the present invention, comprises combustion barrel 1, and cylindrically, turbine can pass into air to combustion barrel 1 wherein.At least arrange two fuel nozzles at the inner chamber of combustion barrel 1, fuel nozzle is positioned at the air intake of combustion barrel 1, and the fuel sprayed from fuel nozzle enters in combustion barrel 1, mixes with air.The direction of fuel nozzle burner oil has certain angle with the airflow direction entering combustion barrel 1, and angle is acute angle, and the one-component of fuel emission direction is identical with air motion direction.Each fuel nozzle all has a set of independently fuel system, and each fuel nozzle is connected to each self-corresponding petrolift 2, by petrolift 2 to pump fuel in fuel nozzle respectively by cartridge 21.Fuel nozzle is fixedly installed in combustion barrel 1, and the angle corresponding setting mutually of each fuel nozzle, enables the fuel in different fuel nozzle mutually cross.
Two or more fuel nozzle is also provided with the igniter of equal number accordingly, and each fuel nozzle of each igniting is all attempted starting, as long as now there is one to complete igniting, the flame ejected other fuel nozzles related together ignite.The probability that igniter cannot be ignited is higher, and the probability that two or more igniter cannot be ignited simultaneously can reduce greatly, thus improves the success rate of igniting.After lighting, combustor enters normal operating conditions, fuel in each fuel nozzle can spray and mutually cross, when the fuel of a fuel nozzle ejection cannot burn completely and utilize, can be sprayed onto on another fuel nozzle, lighted by the thermal-flame of another fuel nozzle, thus realize Thorough combustion utilization.Multiply flame crosses jointly, can make to form higher temperature in combustion barrel 1, and higher temperature also can impel burning completely.Generally, as long as there are two groups of fuel nozzles mutually to cross, by one of them, another is ignited, relative to the combustion system of one flame, more efficiently can utilize fuel.
Provide a kind of preferred technical scheme in the present invention, namely arrange two fuel nozzles and petrolift 2, cartridge 21 adopts copper pipe, and petrolift 2 and cartridge 21 are exposed to outside, can bear high temperature within the specific limits.
Further, in the present invention, also correspondence is provided with detection electric eye, each fuel nozzle arranges a detection electric eye separately, detection electric eye is positioned at one end that fuel nozzle connects cartridge 21, for detecting fuel nozzle whether normal ignition, and by signal transmission and feedback effect to petrolift 2 and igniter 3, control the duty of petrolift 2 and igniter 3.Suddenly extinguish when loss of ignition or in running, petrolift 2 automatically locks, and stops continuing supply fuel; At ignition phase, if light a fire successfully, then control point firearm 3 stops igniting, and burned flame continues fuel to ignite.Two or more detection electric eye can measure the duty of fuel nozzle more accurately, provides data-signal more accurately.
The utilization rate of fuel during in order to improve burning further, also burning web is installed with in combustion barrel 1, burning web is positioned at the openend of fuel nozzle, fuel ejects and can touch burning web, when normal work, burning web is subject to the heating of thermal-flame, keep very high temperature, in combustion barrel 1, form a high-temperature region.The part of fuel be not still fully used under mutual ignition condition can be ejected on burning web, is again heated and lights, to improve the degree of fuel combustion further by the burning web of high temperature.Burning web can be arranged on the mutual intersection of fuel, also can be arranged at closer to exit, and being ignited by secondary ignites with three times separates.
Particularly, lasting high temperature can be born when burning web uses, exotic material be selected, preferably can be set to high temperature titanium net.Certainly, also can first with other the material with similar quality.
Need during install combustion machine to be fixed, the bottom of casing 4 is provided with mounting flange, in order to the position of mounting flange can be finely tuned, mounting flange arranges the waist hole of strip, the part of casing more than 4 can be made to slide along the direction in waist hole, only need during installation, by flange, combustor is fixed on fire door.
Particularly, the fuel nozzle selected in the present invention is high-pressure atomization nozzle, also arranges the steady flame device of eddy flow air distribution in combustion barrel 1.
Set temperature sensor and pressure sensor is gone back in combustion barrel 1, for providing feedback to petrolift 2, the number of fuel metering supply.According to the automatic adjusting size fire of the load variations of heat power equipment, regulate the supply of combustion air simultaneously, ensure that burning is complete, it is reliable to operate steadily, save the energy simultaneously.
When mounted first by flange asbestos pad on combustor, combustion barrel 1 is stretched in burner hearth, aims at screwhole position mounting flange is fixed on body of heater after the adjustment of position.After confirming to stretch into the position of burner hearth, by bolt-locking everywhere, ensure that combustor is installed firmly.
Combustor of the present invention, cooperatively interacts ignite by arranging the relative fuel nozzle of multiple angle, can improve the success rate of igniting on the one hand, also can mutually light a fire on the other hand, and making can not clean-burning complete combustion of fuel, carries out secondary utilization.In addition, being also provided with burning web, forming a high-temperature region when not hindering normal ventilation, if the fuel utilized not yet completely in addition, also again can lighted utilization through this high-temperature region, realize three igniting.These structures can play combustion-supporting effect, promote fuel availability, avoid waste, save cost.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein, can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
