Abstract
The utility model discloses a garbage furnace using coal-water fluid as fuel. The front of the garbage furnace is provided with a delivery device which can deliver the garbage into the furnace chamber. The lower part of the furnace chamber is provided with a multistage fire grate, and the lower part of the front end of the furnace chamber is provided with a drying fire grate air feeder and a fire grate air feeder. The upper part of the furnace chamber is communicated with a secondary combustion chamber, the air outlet of which is in turn connected with an exhaust-heat boiler, an overheater, a coal economizer, an ash separator, a draught fan and a chimney. The furnace wall is provided with a special burner for the coal-water fluid garbage furnace using the coal-water fluid as the fuel. When the special burner of the coal-water fluid garbage furnace is lit up, the garbage can be lit up by the high generated temperature and keep stable burning, and the exhaust-heat boiler can also operate normally. The sufficient burning of the garbage can make the smoke gas without dust get free of the adhered materials when going through the inside wall of the furnace chamber and the pipe wall of the boiler heating surface, so as to ensure the normal combustion. The coal-water fluid coal-water furnace does not waste the oil resources. The utility model has the advantages of low price and convenient application, because the coal resources are rich.
Description
Technical field
The utility model belongs to incinerator, specifically a kind of incinerator that acts as a fuel with water-coal-slurry
Background technology
Incinerator is widely used in the burning processing system of municipal refuse and discarded object at present, and the heat that waste incineration produced can also be used to using for waste heat boiler.But because the composition of rubbish is extremely complicated, its combustibility is relatively poor, and it is not thorough often to burn during waste incineration in the stove, makes that furnace temperature is low, the fluctuation of catching fire is big, therefore can not produce lasting high temperature.If the temperature in the incinerator does not reach predetermined continuous high temperature value, just can not waste incineration is thorough, its waste heat boiler can not normally move; In addition, because burning is not thorough, in the waste incineration process, can produce a large amount of dust, the main component of dust is falling property inorganic matter, inorganic salts, coagulable gaseous contamination material and harmful heavy metallic oxide etc., these dust very easily stick on inboard wall of burner hearth and the boiler heating surface tube wall, have a strong impact on the normal operation of incinerator.In order to make waste incineration thorough, make the temperature in the stove can reach predetermined continuous high temperature value, present incinerator all with light diesel fuel as auxiliary fuel, but light diesel fuel not only costs an arm and a leg, but also the valuable petroleum resources of waste.
The utility model content
Relatively poor for solving rubbish because of combustibility, often burn not thorough during burning, the instability of catching fire, can not produce lasting high temperature in the stove, and because of burning problems such as thoroughly not producing harmful dust, the technical solution of the utility model is: in the front of incinerator, the conveying device that rubbish can be sent into burner hearth is installed, the lower furnace portion of incinerator is provided with multistage fire grate, front end bottom at burner hearth, drying oven discharge fan and fire grate pressure fan are installed, on the furnace wall of the main combustion chamber both sides of burner hearth, be horizontally installed with water-coal-slurry incinerator burner special, upper furnace is communicated with secondary combustion chamber, and the gas outlet of secondary combustion chamber is connected to waste heat boiler successively, superheater, economizer, deduster, air-introduced machine and chimney.
The water-coal-slurry incinerator burner special of installing on the furnace wall of described burner hearth main combustion chamber both sides and the angle of both sides furnace wall are the 55-65 degree.
For the thing that do not burn that flue gas is taken out of burns away, water-coal-slurry incinerator burner special is installed also on the furnace wall of secondary combustion chamber.
After waste conveyor is sent into rubbish on the inner of the boiler chamber row, the blowing of drying fire grate pressure fan, rubbish with moisture content evaporate earlier, light the water-coal-slurry incinerator burner special that is installed on the furnace wall of main combustion chamber both sides, the high temperature of generation is lighted rubbish; When there were the angle of 55-65 degree in described burner and both sides furnace wall, the flame level of burner ejection was sprayed forward, ran into the stokehold wall and can turn back to both sides and circle round, and made flame longer in the time that burner hearth stops, thereby waste incineration was got more abundant.Do not burn thing when entering secondary combustion chamber in the rubbish with flue gas, process water-coal-slurry incinerator burner special lighting again, then all combustibles in the flue gas are almost all thoroughly burnt, because lighting of water-coal-slurry incinerator burner special, can keep continual and steady high temperature in the stove, its with waste heat boiler also can normally move; Moreover the flue gas that does not contain dust does not substantially have bur to adhere to during through inboard wall of burner hearth and boiler heating surface tube wall, just can not influence the normal combustion of incinerator yet.After tested, less than 1 grade, dust concentration is less than 100mg/m from the lingemann blackness of above-mentioned water-coal-slurry incinerator discharged flue gas
3, CO
2Concentration is less than 400mg/m
3, meet the requirement of national environmental protection; Also solved simultaneously with the burn away the refuse problem of the expensive and waste petroleum resources of price of light diesel fuel, compared with the combustion light diesel fuel incinerator of identical tonnage, the fuel cost of water-coal-slurry incinerator can save 3/4.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a scheme of installation of the present utility model.
The specific embodiment
Among Fig. 1,, the waste conveyor of being made up of hopper 1, conveyer 2, batcher 3 is installed in the stokehold of water-coal-slurry incinerator, the bottom of the front furnace of water-coal-slurry incinerator, be provided with multistage fire grate 4, below fire grate 4, drying oven discharge fan 5 and fire grate pressure fan 6 be installed; On the furnace wall of the both sides of burner hearth main combustion chamber 8, be horizontally installed with water-coal-slurry incinerator burner special 7, the end of multistage fire grate 4 is equipped with dragveyer 9; Be communicated with secondary combustion chamber 10 in upper furnace, the gas outlet of secondary combustion chamber 10 is connected with waste heat boiler 12, superheater 13, economizer 14, deduster 15, air-introduced machine 16 and chimney 17 successively.The described water-coal-slurry incinerator burner special of installing on the furnace wall of burner hearth main combustion chamber 8 both sides 7 is the 55-65 degree with the angle of both sides furnace wall, be preferably 60 degree, when the flame level is sprayed forward, running into the stokehold wall can turn back to both sides and circle round, make flame longer in the time that burner hearth stops, must be to the waste incineration that enters on the fire grate with more thorough; It is a pair of that the water-coal-slurry incinerator burner special of installing 7 distributes about can being, also can increase and decrease the installation number according to the size of incinerator.
For the thing that do not burn that flue gas is taken out of burns away, the water-coal-slurry incinerator burner special 11 of horizontal direction also is installed on the furnace wall of secondary combustion chamber 10, the number of installation is also decided by the size of secondary combustion chamber.
