Abstract
The utility model discloses a vertical-typed water-coal-slurry industrial boiler, and aims at overcoming the weaknesses of the prior horizontal water-coal-slurry boiler that the combustor is mounted in the horizontal direction, the fuel flows horizontally in a single way in the pre-combustion chamber, and the staying time of the fuel is short, and the combustion is inadequate, and the heating efficiency of the boiler cannot be greatly improved. The boiler comprises an integral boiler wall body, a water-coal-slurry combustor, a fuel pre-heating chamber, a vertical-typed hearth, a coal saver and an air pre-heater, wherein, the water-coal-slurry combustor is installed in the vertical direction; an angle that is smaller than 30 degrees and faces towards the hearth is formed between the central line of the nozzle and the central vertical line of the front boiler wall. Compared with the water-coal-slurry combustor of the horizontal water-coal-slurry boiler, the vertical-typed combustor can force the flame to rush to the bottom of the boiler, and then to flow out upwards in a nearly U shape, so as to form a large pre-combustion chamber in front of the hearth; the water-coal-slurry encounters higher temperature and longer distance, thereby prolonging the staying time of the water-coal-slurry in the hearth, and improving the temperature of the ignition area of the water-coal-slurry, so that the combustion of the fuel is more adequate and stable, thereby further reducing the emission of the smoke, dust and the sulfur dioxide.
Description
Technical field
The utility model belongs to the boiler class, specifically a kind of Industrial Boiler of making fuel with water-coal-slurry.
Background technology
With the water-coal-slurry is the boiler of fuel, reduced the discharging of flue dust and sulfur dioxide, alleviated pollution, reduced the harm that human body is caused air, receive good economic benefits and social benefit after the use, the boiler that for example present part power station is used is fuel with the water-coal-slurry.Coal water slurry boiler when burning and common coal-burning boiler relatively, the water-coal-slurry of burning is that the despumation of in advance cleaned coal being carried out washing and partial desulfurization, deliming is handled, simultaneously again with pipeline carry, spray combustion, thereby furnace flame stablizes, fuel combustion is abundant.
Coal water slurry boiler all is horizontal at present, be that water coal slurry burner is that level is installed on the vertical preceding furnace wall, coal water slurry fuel is unidirectional bottom horizontal flow sheet through precombustion chamber the time, water-coal-slurry is ejected in the precombustion chamber with burner, but owing to be unidirectional bottom horizontal flow sheet, the time that fuel stops in stove is short, though better with common coal-burning boiler than fuel combustion, burning or not ideal; Simultaneously, because the coal water slurry fuel of horizontal coal water slurry boiler is unidirectional bottom horizontal flow sheet during through precombustion chamber, the heat that fuel combustion produces can not fully carry out heat exchange, causes the thermal efficiency of boiler not have biglyyer and improves.
The utility model content
Technical problem to be solved in the utility model is, overcoming existing horizontal coal water slurry boiler burner level installs, fuel is unidirectional bottom horizontal flow sheet through precombustion chamber the time, cause fuel to lack, can not burn more fully at residing time in furnace, cause the thermal efficiency of boiler that the shortcoming of bigger raising can not be arranged, a kind of vertical water-coal-slurry Industrial Boiler is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: vertical coal water slurry boiler comprises whole furnace wall body, water coal slurry burner before being installed on the furnace wall, the fuel preheating chamber of nearly water coal slurry burner, the vertical furnace chamber that constitutes between furnace wall body and furnace roof canopy and the furnace bottom, the width of cloth that the burner hearth madial wall is arranged is penetrated heating surface, superheater, drum and convection heating surface, the economizer of preheating feedwater, air preheater, slag remover below the furnace bottom and ashpit, described water coal slurry burner is vertical layout, between the nozzle centerline of burner and the preceding furnace wall central vertical line, have towards the angle of burner hearth direction less than 30 °.
The utility model also has following technical characterictic:
The nozzle centerline of described water coal slurry burner, and between the preceding furnace wall central vertical line is 15 ° towards the angle of burner hearth direction;
The nozzle centerline of described water coal slurry burner, and between the preceding furnace wall central vertical line, have towards the angle of burner hearth direction less than 30 °, it is the position that water coal slurry burner is installed on the preceding furnace wall of boiler, have one domatic less than 30 ° of angles of facing upward to be arranged with vertical preceding furnace wall, the center line of water coal slurry burner vertical with domatic installation;
The nozzle of described water coal slurry burner is 4.5-5.5 meters from the furnace bottom height;
The nozzle of described water coal slurry burner is 5 meters from the furnace bottom height;
The interior shape of the whole furnace chamber of described boiler is set to, and can make the flow of flue gas direction be the passage that the π type distributes.
Advantage of the present utility model and good effect are, because the burner of vertical coal water slurry boiler, between its nozzle centerline and the front wall central vertical line, have towards the angle of burner hearth direction less than 30 °, the burner of vertical water-coal-slurry forces the at first oblique furnace bottom that rushes at of flame, then the back top is approximate U type shape outflow, formed bigger precombustion chamber at furnace front, make precombustion chamber be not less than 1/4th to 1/5th of furnace volume, water-coal-slurry is after the burner ejection, run into higher temperature and long stroke, compare with the unidirectional bottom horizontal flow sheet burning of the burner water-coal-slurry of horizontal coal water slurry boiler, prolonged the time of staying of water-coal-slurry in burner hearth, there is time enough to make water evaporates in the water-coal-slurry, improved the ignition zone temperature of water-coal-slurry greatly, fuel further is heated equably, it is more abundant that cool water mixture burning is got, flame is more stable, thereby has further reduced the discharging of flue dust and sulfur dioxide; The heat that the fuel combustion flue gas that approximate U type shape flows out has can fully carry out heat exchange in stove, improved the thermal efficiency of boiler greatly.
