Abstract
The invention provides a kind of oxygen-enriched few-oil ignition system of boiler, including burner；The front end of the burner is additionally provided with auxiliary oil gun, and the rear end of the burner is provided with micro- oil burner, and micro- oil burner is in charge of A and be connected with oily gas-distributing fan and hot blast.The characteristics of present invention makes the existing few-oil ignition technology fuel-economizing of the system, efficiency height etc. by oxygen-enriched pipeline and auxiliary oil gun, the advantage of oxygen-enriched combustion technology augmentation of heat transfer etc. is contained again.The realization of this combustion technology is mostly based on few-oil ignition combustion technology, oxygenation transformation is carried out to few-oil ignition combustion system again, allow specific region oxygen concentration in oil-minimum start-up burner to get a promotion, form oxygen-enriched combusting atmosphere so that the fuel in burner is more prone to light and after-flame.Power plant for using anthracite W flame, is compared, rate of economizing gasoline is up to more than 90%, and oil-saving effect is notable with traditional big grease gun igniting mode.
Description
Technical field
The present invention relates to a kind of oxygen-enriched few-oil ignition system of boiler.
Background technology
Micro- oil gasification direct-fire is the Gasifying Small Oil Gun reinforcing being combined using medium atomization (compressed air) with gasifying
Combustion technology makes fuel oil fully burn, and the amount of fuel of very little is achieved with a rigidity relatively strong, temperature very high stable torch, by
In the torch temperature up to 1600-1800 DEG C, it is heated quickly when coal dust is by torch, and makes pulverized coal particle rupture crushing, it is fast
Speed is ignited.According to the principle of fractional combustion, make coal dust in Initial Stage after Ignition just fully burning as far as possible, reach pulverized coal boiler ignition
Start the purpose with low-load combustion-stabilizing.It was verified that utilizing this micro- oil gasification direct-fire technology burning meager coal and anthracite
When, use the problem of coal burner has complicated and insufficient coal dust firing at present.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of oxygen-enriched few-oil ignition system of boiler.
The present invention is achieved by the following technical programs.
The oxygen-enriched few-oil ignition system of a kind of boiler that the present invention is provided, including burner；The front end of the burner is also set
Auxiliary oil gun is equipped with, the rear end of the burner is provided with micro- oil burner, micro- oil burner and oily gas-distributing fan and hot blast
It is in charge of A connections, the auxiliary oil gun is in charge of B with hot blast and is connected, and the auxiliary oil gun is also connected with sweeping wind pipe, the burner
The upper front end for also having oxygen-enriched main line to be connected to micro- oil burner.
Also it is connected on micro- oil burner with oxygen-enriched branch pipeline.
The oxygen-enriched branch pipeline is accessed in micro- oil burner jointly with oily gas-distributing fan.
The oxygen-enriched branch pipeline and oxygen-enriched main line are connected with oxygen-enriched pipeline jointly.
The hot blast is in charge of A and hot blast is in charge of B and is connected jointly with hot-blast pipe line.
The beneficial effects of the present invention are：The existing few-oil ignition technology section of the system is made by oxygen-enriched pipeline and auxiliary oil gun
The characteristics of oil, efficiency height etc., the advantage of oxygen-enriched combustion technology augmentation of heat transfer etc. is contained again.The realization of this combustion technology is mostly
Oxygenation transformation is carried out based on few-oil ignition combustion technology, then to few-oil ignition combustion system, is allowed in oil-minimum start-up burner
Specific region oxygen concentration gets a promotion, and forms oxygen-enriched combusting atmosphere so that the fuel in burner be more prone to light and
After-flame.Power plant for using anthracite W flame, is compared with traditional big grease gun igniting mode, and rate of economizing gasoline is up to more than 90%, fuel-economizing
Effect is notable.
