Description
Technical field
The present invention relates to a kind of using method and equipment of fuel, relate in particular to a kind of using method and equipment that is used for the petroleum coke powder fuel of melten glass.
Background technology
At present, the tank furnace that China glass manufacturing works fusion cast glass is used, annealing furnace and the used fuel of baking flower stove have following a few class: heavy oil, coal tar, Sweet natural gas, producer gas, the burnt slurry of water etc., heavy oil, incendiary calorific value height, national most glasswork all is the main fuel of fusion cast glass and annealing baking flower with heavy oil before 3 or four years, but in recent years along with the continuous rising of International Crude Oil, factory changes one after another burns the cheap coal tar of price comparison, the output of coal tar declines to a great extent now, price rises, about 1400 yuan per ton from June, 2005 have risen to about 3000 yuan per ton up till now, fuel accounts for about 1/3 in the production cost of glasswork, and therefore many glasswories stop production or dwindle industrial scale.Producer gas is because calorific value is low, and the glass melting rate is low, and general glasswork near the coal-producing area uses more.Easy to use and the cleaning of Sweet natural gas, but price height, factory can't bear.The producer that also has imitates the burning way of coal water slurry boiler in order to reduce fuel cost, converts water with the refinery coke of pulverizing, and add thickening stabilizer and make water Jiao slurry as tank furnace, annealing furnace, the fuel of baking flower stove, but consume greatly, and influence the whiteness of glass.
Summary of the invention
The invention provides a kind ofly as seen reduce cost, the using method and the equipment of petroleum coke powder fuel simple to operate.
The present invention adopts following technical scheme:
A kind of using method that is used for the petroleum coke powder fuel of melten glass, this method may further comprise the steps:
1. fuel screening of step: the foreign material in the refinery coke are removed,
Step 3. fuel is ground: the refinery coke coarse grain is ground, and obtaining granularity behind the mill is 150～1000 purpose petroleum coke powders,
4. fuel deironing of step: the petroleum coke powder that 3. step is obtained carries out deironing by magnetic field to be handled, obtain iron-holder less than ten thousand/ petroleum coke powder,
Step is the fuel drying 5.: petroleum coke powder fuel carried out drying treatment, makes the water-in-fuel amount less than 8%,
Step is transport of fuel 6.: the petroleum coke powder transport of fuel is arrived the powder feeding machine,
Step is the pre-mixing of fuel and air 7.: carry out pre-mixing at mixing tank PetroChina Company Limited. coke powder fuel and air,
Step 8. fuel is carried: utilizes the pressurized air in first transfer lime, petroleum coke powder fuel and air is transported to first burner,
Step is fuel combustion 9.: petroleum coke powder that sprays from first burner and air admission kiln also burn in kiln.
A kind of use equipment that is used for the petroleum coke powder fuel of melten glass, comprise feeding machine, powder feeding machine, mixing tank, first transfer lime, first burner, gas-holder, kiln, wherein the discharge port of feeding machine links to each other with the opening for feed of powder feeding machine, the discharge port of powder feeding machine links to each other with the opening for feed of mixing tank, first transfer lime is connected on the gas-holder, first transfer lime is provided with opening for feed and this opening for feed communicates with the discharge port of mixing tank, first burner is located at the exit of first transfer lime, the discharge port of first burner and the feeding inlet of kiln.
Compared with prior art, the present invention has the following advantages:
1, the present invention can reduce cost.The employing petroleum coke powder acts as a fuel, compare with fuel such as heavy oil, coal tar, Sweet natural gas, producer gas, the burnt slurries of water, can reduce production costs, with the fuel of petroleum coke powder as melten glass, compared with other fuel,, has good price advantage as heavy oil, coal tar, Sweet natural gas etc., reduce the cost of fuel, also just made the manufacturing cost of glass reduce greatly; If directly petroleum coke powder is burnt, then because the iron-holder in the petroleum coke powder is higher, can directly have influence on the whiteness of glass, do not reach the processing requirement of melten glass, since the iron-holder of the petroleum coke powder fuel that obtains of the technical solution used in the present invention less than ten thousand/, so not only can reduce cost when being used for melten glass but also can reach the processing requirement of melten glass, kept the whiteness of glass.
2, the present invention can make the petroleum coke powder full combustion of fuel, has improved utilization ratio of raw materials.Petroleum coke powder fuel can evenly be stirred the screw feeder from feeding machine, after fuel enters the powder feeding machine, after evenly being screened, powder feeding machine PetroChina Company Limited. coke powder fuel enters in the mixing tank, in mixing tank, finish the pre-mixing of fuel and gas, by transfer lime, petroleum coke powder fuel mixes once more with the mixture and the gas of gas, just makes the ratio of mixture of fuel and gas reach optimum value, help the abundant burning of petroleum coke powder fuel, improved the utilization ratio of fuel.
