Description
Technical field
The invention belongs to burner field, more particularly to a kind of alcohol radical combusting vaporization burner.
Background technology
Alcohol-based fuel is for primary raw material with alcohols (methanol, ethanol etc.), and by special process formula, synthesis is blent through chemistry
A kind of liquid fuel, be a kind of fuel of cleaning, the industries such as boiler, kiln, aluminium melting furnace can be widely used in.Combustion at present
The burner for burning alcohol-based fuel generally uses spray burning pattern, but because the latent heat of vaporization of alcohols, particularly methanol compares
Greatly, such as the latent heat of vaporization of methanol is about 4 times of diesel oil, and this, which may result in, occurs area of topical hypothermia in burner hearth or combustion chamber
Domain, cause the pollutants such as incomplete combustion and formaldehyde emission.In order to solve this problem, it can use and evaporate fuel in advance
Into the mode of gas, at present generally use be electricity or flue gas fuel container mode, such as patent
CN201410223125.0, CN201620300450.7, CN201611102615.0, CN201520498520.X etc..But this
There is system complex in a little methods, fuel control is difficult, adjusts the problems such as dumb, and have gas leakage or container explosion etc.
Potential safety hazard.
The content of the invention
For overcome the deficiencies in the prior art and the problem of exist, the present invention provides a kind of alcohol radical combusting vaporization burner,
It is safe and reliable, it is easy to control.
The present invention is achieved by the following technical solutions：
A kind of alcohol radical combusting vaporization burner, including casing, be provided with the casing airflow pipe that is connected with each other and
Port, burner is provided with port, burner is connected with evaporation tubes, and evaporation tubes are connected with high-temperature gas supply pipe
Road, evaporation tubes are interior to be provided with atomizer, and atomizer is connected with cartridge.
The evaporation tubes are located at the center of airflow pipe, and evaporation tubes are coaxially arranged with airflow pipe.
The atomizer is located in evaporation tubes at the center of burner one end.
Cyclone is provided between the airflow pipe and port.
The burner is fixed on the central axis of cyclone, and extends in port.
The high-temperature gas supply line is connected to high-temperature flue gas pipe.
The present invention is provided with evaporation tubes, and high-temperature gas is passed through evaporation tubes, atomizer by high-temperature gas supply line
Alcohol-based fuel is sprayed into evaporation tubes, vaporized after the alcohol-based fuel chance high-temperature gas of atomization, vaporization fuel mixing high temperature gas lead to
Cross burner and spray into the air mixed combustion conveyed in port with airflow pipe, alcohol-based fuel fires again after overflash
Burn, on the one hand eliminate the area of topical hypothermia in burner hearth or combustion chamber, avoid the generation of incomplete combustion product, reduce dirty
Thing discharge is contaminated, while improves efficiency of combustion and fuel availability；On the other hand, mixed after alcohol radical combusting vaporization with high-temperature gas
After-combustion can reduce the peak flame temperature in burner hearth or combustion chamber, and this can play a part of reducing discharged nitrous oxides.
Burnt again after being mixed after alcohol radical combusting vaporization with high-temperature gas and also help shortening flame, simultaneously because the temperature of gaseous mixture is higher than
Normal temperature air, flame holding can also be improved.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：1- casings, 11- airflow pipes, 12- ports, 2- burners, 3- evaporation tubes, 4- high-temperature gases
Supply line, 5- atomizers, 6- cartridges, 7- cyclones.
Embodiment
For the ease of the understanding of those skilled in the art, the present invention is made below in conjunction with the drawings and specific embodiments further
It is described in detail.
Such as Fig. 1, a kind of alcohol radical combusting vaporization burner, including casing 1, it is defeated that the air being connected with each other is provided with casing 1
Send pipeline 11 and port 12, airflow pipe 11 is delivered the air at port 12, port 12 be located at burner hearth or
In combustion chamber.Burner 2 is provided with port 12, burner 2 is connected with evaporation tubes 3, and evaporation tubes 3 are connected with high-temperature gas
High-temperature gas is passed through in evaporation tubes 3 by supply line 4, high-temperature gas supply line 4.Atomizer is provided with evaporation tubes 3
5, atomizer 5 is connected with cartridge 6, and alcohol-based fuel is delivered to atomizer 5 by fuel channel 6, and atomizer 5 is by alcohol radical
Fuel atomization sprays.Cyclone 7 is provided between airflow pipe 11 and port 12, air can be formed after cyclone 7
Central backflow area, play a part of stable flame.Burner 2 is fixed on the central axis of cyclone 7, and extends to port 12
In, this may be such that the blow-off point position of burner 2 is optimal, lift combustion efficiency.
Evaporation tubes 3 are located at the center of airflow pipe 11, and evaporation tubes 3 and airflow pipe 11 are coaxially arranged.
