Abstract
The utility model 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 with oily gas-distributing fan and hot blast and is connected.The characteristics of the utility model makes the existing few-oil ignition technology fuel-economizing of the system, efficiency height etc. by oxygen-enriched pipeline and auxiliary oil gun, the advantages of containing oxygen-enriched combustion technology augmentation of heat transfer etc. 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, compared with traditional big grease gun igniting mode, for rate of economizing gasoline up to more than 90%, oil-saving effect is notable.
Description
Technical field
It the utility model is related to a kind of oxygen-enriched few-oil ignition system of boiler.
Background technology
Micro- oil gasification direct-fire is to be strengthened using medium atomization (compressed air) with the Gasifying Small Oil Gun being combined that gasifies
Combustion technology makes fuel oil fully burn, and the amount of fuel of very little is achieved with the stable torch that a rigidity is relatively strong, temperature is very high, by
In the torch temperature up to 1600-1800 DEG C, it is heated quickly when coal dust passes through torch, and crushes pulverized coal particle rupture, it is fast
Speed is ignited.According to the principle of fractional combustion, coal dust is just fully burnt as far as possible in Initial Stage after Ignition, reach pulverized coal boiler ignition
Start the purpose with low-load combustion-stabilizing.It was verified that utilize this micro- oil gasification direct-fire technology burning meager coal and anthracite
When, use coal burner the problem of complicated and coal dust firing is insufficient to be present at present.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of oxygen-enriched few-oil ignition system of boiler.
The utility model is achieved by the following technical programs.
The oxygen-enriched few-oil ignition system of a kind of boiler provided by the utility model, including burner；The front end of the burner
Be additionally provided with auxiliary oil gun, the rear end of the burner is provided with micro- oil burner, micro- oil burner and oily gas-distributing fan and
Hot blast is in charge of A connections, and 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 combustion
There is the front end that oxygen-enriched main line is connected to micro- oil burner in burner.
Also it is connected on micro- oil burner with oxygen-enriched branch pipeline.
The oxygen-enriched branch pipeline accesses 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 utility model are：The existing few-oil ignition skill of the system is made by oxygen-enriched pipeline and auxiliary oil gun
The characteristics of art fuel-economizing, efficiency height etc., the advantages of containing oxygen-enriched combustion technology augmentation of heat transfer etc. again.The realization of this combustion technology
Mostly based on few-oil ignition combustion technology, then oxygenation transformation is carried out to few-oil ignition combustion system, allow few-oil ignition combustion
Specific region oxygen concentration gets a promotion in device, forms oxygen-enriched combusting atmosphere so that the fuel in burner is more prone to a little
Combustion and after-flame.Power plant for using anthracite W flame, compared with traditional big grease gun igniting mode, rate of economizing gasoline up to more than 90%,
Oil-saving effect is notable.
