Description
Technical field
The present invention relates to a kind of coal burner igniter, particularly a kind of coal burner tiny-oil ignition device.
Background technology
Coal burner is one of vitals of heat energy process units; it provides thermal source for whole heat energy system; the heat that only have the burner guarantee coal dust of function admirable in the combustion space, evenly to distribute rapidly, in time on fire, completing combustion also provides abundance as requested; form a rational temperature field and thermal regulation; for heat energy apparatus provides best thermal technology's condition; thereby make heat energy apparatus give full play to function, accomplish high-quality, efficient, needs that environmental protection is satisfied in the running of low consumption long-term safety simultaneously.
At present, the coal burner igniting mainly contains dual mode, is respectively fuel ignition and plasma igniting.Although the latter has saved ignition oil, one time cost of investment is too high, and also need consume than multi-energy in the ignition process; Adopt oil drop fire mode then to face firing coal-dust how rapidly, reduce the problem of oil consumption.If can smooth combustion successfully be lighted and be realized to coal burner with micro-fuel oil, then to reducing enterprise's power consumption, it is significant to promote energy-saving and emission-reduction.
Summary of the invention
The purpose of this invention is to provide a kind of coal burner tiny-oil ignition device, by the concentrated coal air mixture in the oil gun ignition channels pipe of retractable in the igniter tube channel, form the stable little torch of coal dust, then regulate wind speed, pulverized coal flame slowly is blown out to outside the igniter tube channel, the coal dust that is arranged in the future self-ignition of the refractory ceramics bluff body device tube channel in igniter tube channel exit this moment carries out deep or light separation, guarantee that the coal dust torch further amplifies, finally realize the burner igniting.
The object of the present invention is achieved like this: a kind of coal burner tiny-oil ignition device is characterized in that: be provided with liner high-temperature flame-proof pottery the circular igniter tube channel with control valve, extend into the igniter of igniter tube channel inside and with the coaxial telescopic torch oil gun of igniter tube channel, be located at the high-temperature flame-proof pottery bluff body of the igniter tube channel port of export.
Described igniter tube channel is elbow structure, and liner high-temperature flame-proof potsherd.
Described torch oil gun one end extend in the igniter tube channel and with igniter tube channel coaxial arrangement, torch oil gun is the free-extension igniter tube channel of coming in and going out vertically.
Described high-temperature flame-proof pottery bluff body is taper.
Described cone high-temperature refractory bluff body center has for the freely through centre bore of torch oil gun.
Described igniter tube channel and torch oil gun are joint pipe structure.
Described igniter is arranged on the tube wall of igniter tube channel.
The reasonable science of the present invention, simple in structure, by the circular igniter tube channel with control valve of liner high-temperature flame-proof pottery, extend into the igniter of igniter tube channel inside and install with the coaxial telescopic torch oil gun of igniter tube channel, the high-temperature flame-proof pottery bluff body that is located at the igniter tube channel port of export and form, manufacture easily, easy to use, effective, as to save coal burner igniting oil consumption has reduced enterprise's fuel cost.
The present invention adopts the course of work of micro-fuel oil firing coal-dust burner to be: torch oil gun is retreated inlet point firearm tube channel, light torch oil gun, form the localized hyperthermia district, self-ignition device tube channel sprays into through concentrated coal air mixture, behind the little torch of stable coal dust to be formed, stop the fuel oil supply, slowly regulate wind speed the coal dust torch is moved to the igniter tube channel port of export outward, strengthen gradually the amount of sending into of coal air mixture, at this moment, the refractory ceramics bluff body that is positioned at the igniter tube channel port of export plays the effect of deep or light separation to wind powder mixture, behind the large torch of stable coal dust to be formed, other spouts of burner feed coal dust in a large number, air is behind stable ignition, ignition process is finished in the supply of halt firearm tube channel fuel.
Beneficial effect of the present invention is: coal dust namely stops the fuel oil supply after little torch is stablized in the inner formation of igniter tube channel, adopt gradually firing coal-dust burner of the little torch of coal dust, has saved great amount of fuel oil.In addition, the refractory ceramics bluff body that is arranged in the igniter tube channel port of export has played the effect that coal powder light-dark separates to wind powder mixture, is conducive to the formation of the stable large torch of coal dust firing, and can plays the effect that reduces discharged nitrous oxides in the coal-fired process.
Innovation of the present invention, described igniter tube channel liner high-temperature flame-proof pottery is conducive to form the localized hyperthermia district in the igniter tube channel, has improved igniter service life.
Innovation of the present invention is retracted into the igniter tube channel during torch oil gun igniting, has reduced radiation loss, forms the localized hyperthermia district, is conducive to rapid igniting.
Innovation of the present invention adopts torch oil gun at first to light through the coal dust after concentrated, has shortened the fuel ignition time, has significantly reduced fuel consumption.
Innovation of the present invention, adopt control valve, after the little torch of coal dust forms, slowly blow out the igniter tube channel by regulating wind speed, light gradually the coal dust after the refractory ceramics bluff body separates, enlarge and form the stable large torch of coal dust, improved Ignition Stability, the simultaneously deep or light separation of coal dust has reduced nitrogen oxide emission.
