The utility model relates to a power plant boiler fuel ethanol burner, which belongs to the supporting device of the power plant boiler. One end of the combustion chamber is the fuel outlet, and the air distribution chamber with the air distribution port is socketed with the combustion chamber. There is a vent hole at the socket joint between the combustion chamber and the air distribution chamber. The curved blade type flow stabilizer is fixedly connected inside the combustion chamber. The other end of the combustion chamber is connected to the pre-combustion chamber, and the serpentine tube is fixedly connected to the pre-combustion chamber. One end of the serpentine tube is connected to the ethanol inlet, and the other end is connected to the ignition nozzle. The ignition nozzle is connected to the pre-combustion chamber. There is a distribution vent in the room. The advantages are: the structure is novel, and the ethanol that enters the boiler to ignite the pulverized coal is fully vaporized to realize the complete vaporization and combustion of the fuel ethanol; a small amount of fuel ethanol is used to directly ignite the pulverized coal, and green energy is used in the power station boiler to realize clean emission of the power station boiler.
Description
Technical field
The utility model belongs to the station boiler corollary apparatus, refers in particular to station boiler igniting and steady combustion auxiliary combustion equipment.
Background technology
Station boiler all the time with light diesel fuel as the igniting and combustion-supporting fuel, its combustibility gets the nod.At present, development along with society, the import volume of China's fuel oil increases year by year, because the lasting rising of world energy sources price, seriously restricted the tremendous development of Chinese national economy, people's the energy and environmental consciousness strengthen day by day simultaneously, and the fuel of selecting alternative green energy resource will be inexorable trend.The production of fuel ethanol raw material is biogenic, and it is a kind of reproducible energy.The CO that is discharged in the ethanol combustion process
2Corresponding emission with sulfurous gas all is lower than gasoline combustion and is produced because its ratio of combustion regular gasoline is more complete, makes its CO discharge capacity to reduce about 30% again.Thereby alcohol fuel is called as " green energy resource " or " clean fuel ".And, the CO that the alcohol fuel burning is discharged
2With the CO that biogenic growth consumed as raw material
2Quantitatively remain basically stable, this is significant to reducing atmosphere pollution and inhibition " greenhouse effects ".
Liquid ethanol when burning since during liquid atomizing its length of flame and flame temperature all not good, on firing coal-dust, can occur being difficult for lighting, situation such as unstable combustion.This has all restricted the application of ethanol in station boiler in the past.
Summary of the invention
The utility model provides a kind of station boiler alcohol fuel burner, and its length of flame and flame temperature are all not good when solving the liquid ethanol burning because during liquid atomizing, can occur being difficult on firing coal-dust lighting, the problem of unstable combustion.The technical scheme that the utility model is taked is: combustion chamber one end is a fuel outlet, distribution plenum and this combustion chamber socket with air distribution outlet, in this combustion chamber and distribution plenum socket place passage is arranged, camber blades formula flow straightener is fixedly connected on inside, combustion chamber, and this combustion chamber other end connects precombustion chamber, and snakelike pipeloop is fixedly connected in this precombustion chamber, this snakelike pipeloop one end is connected with the ethanol import, the other end is connected with ignition burner, and this ignition burner is connected with precombustion chamber, and air distribution outlet is arranged on the precombustion chamber.During work, ethanol enters the snakelike pipeloop from import, sprays through ignition burner, lighted, carry out partial combustion with little air, the ethanol in precombustion chamber in the heating coil circle makes it vaporization, ethanol after the vaporization enters the combustion chamber, and mixed with air, further burning sprays from fuel outlet at last, enter boiler, firing coal-dust.
Advantage of the present utility model is: novel structure, the ethanol that enters the boiler firing coal-dust is fully vaporized, and realize the complete vaporization combustion of alcohol fuel; Use the direct firing coal-dust of micro-alcohol fuel, on station boiler, adopt green energy resource, realize the discharging of station boiler cleaning.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Combustion chamber 1 one ends are fuel outlet 10, distribution plenum 2 and this combustion chamber socket with air air distribution outlet 3, in this combustion chamber and distribution plenum socket place passage is arranged, camber blades formula flow straightener 4 is fixedly connected on inside, combustion chamber, and this combustion chamber other end connects precombustion chamber 5, and snakelike pipeloop 6 is fixedly connected in this precombustion chamber, this snakelike pipeloop one end is connected with ethanol import 7, the other end is connected with ignition burner 8, and this ignition burner is connected with precombustion chamber, and air distribution outlet 9 is arranged on the precombustion chamber.
