Abstract
The present invention belongs to a combustion method of fuels in a glass melting furnace, particularly to a combustion method of synthetic petroleum slurry in a float glass melting furnace. Firstly, the synthetic petroleum slurry is respectively transported to the places below small furnace necks at both sides of the glass melting furnace, the synthetic petroleum slurry which is distributed to each spray gun branch enters the spray guns for the synthetic petroleum slurry, and simultaneously, air used for the combustion of the synthetic petroleum slurry enters the periphery of a mist torch for the synthetic petroleum slurry; finally, the synthetic petroleum slurry drips enter the float glass melting furnace, are heated to the temperature from 50DEG C to 140DEG C and are mixed with the air, the water is evaporated, and the volatile components are volatilized, and coke particles in synthetic petroleum slurry drips are burnt up. The method which combusts synthetic petroleum slurry in the glass melting furnace has the characteristics of good combustion effect, stable and reliable operation, stable and low price, sufficient goods supply, cleanness and environmental protection, and the present invention has great competitive advantage.
Description
Technical field
The invention belongs to the combustion method of fuel in the glass melter, the combustion method of particularly a kind of synthetic petroleum thick liquid in float glass smelting kiln.
Technical background
At present, produce float glass both at home and abroad, all adopting fuel oil or coal tar is fuel, the burning in float glass smelting kiln, and its weak point is: the fuel oil shortage is difficult for buying, the cost height; Coal tar is because viscosity is little, and water content is big, and is big in the brightness of combustion process moderate heat root, and it is stifled that gas takes place simultaneously easily, increased the scaling loss to the kiln body; Moreover because the heat loss height, fuel consumption increases, and its burning cost is the same very high with fuel oil.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide that a kind of cost is low, ample supply and prompt delivery, the combustion method of synthetic petroleum thick liquid in float glass smelting kiln that gas is stifled, the kiln body do not had damage can not take place.
The technical scheme that technical solution problem of the present invention adopts is: at first synthetic petroleum thick liquid is delivered to respectively under the port neck of glass melter both sides by pump, pressure is 0.3～1.2Mpa, and temperature is 20～70 ℃; Be assigned to the synthetic petroleum thick liquid of every spray gun branch road, through reversing purging valve automatic reverse control or artificial commutation control, enter into the synthetic petroleum thick liquid spray gun, with compressed air is atomizing medium, air pressure is 0.5～1.0Mpa, make atomizing medium form synthetic petroleum thick liquid mist torch, synthetic petroleum thick liquid mist torch enters on every side for the required air of synthetic petroleum thick liquid burning simultaneously; At last, the synthetic petroleum slurry drops entered heat 50～140 ℃ in the float glass smelting kiln and mix with air, earlier with water evaporates, volatile matter volatilization and cause that the coke granule in the synthetic petroleum slurry drops fire burns then is up to after-flame.
The invention has the beneficial effects as follows: adopt this method synthetic petroleum thick liquid combustion efficiency of burning in glass melter good, the synthetic petroleum slurry viscosity is lower than oil, is easy to regulate, and minimum load adjusts 40%, and it is easy to adjust to burn, stable and reliable operation; In manufacture process, use wet ball mill, defibrination temperature low (50～60 ℃), safety; Synthetic petroleum thick liquid has good mobility and stability, and can equally store, transport by the image-stone oil product, and have nonflammable, non-staining excellent characteristic, be to produce the both economical and practical fuel of float glass at present; Because at present the international market oil price improves constantly, use the enterprise of oil can't bear the heavy load, and synthetic petroleum thick liquid price steadiness and low, ample supply and prompt delivery, the environmental protection characteristic that has cleaning again has bigger competitive advantage.
The specific embodiment
Specific implementation method of the present invention: synthetic petroleum thick liquid is by 50～70% petroleum coke powder and about 0.5～1% microchemistry additive, the slurry that all the other are prepared from for water; It is a kind of fuel slurry, can be as oil pumping, atomizing, storage and smooth combustion, and its calorific value is equivalent to 1/3 to 2/3 of fuel oil, the accessory substance when wherein petroleum coke powder is the feedstock oil cracking at high temperature production light-end products of delayed coking unit; The output of petroleum coke powder is 25～30% of feedstock oil; Its low heat valve is about 1.5～2 times of coal, content of ashes is not more than 0.5%, volatilization is divided into about 11%, quality approaches anthracite, the firm body oil product of petroleum coke powder grey, having metallic luster, be porous, is to form the charcoal body thing that granular, column or needle-like constitute by small graphite crystallization; The petroleum coke powder component is a hydrocarbon, and carbon containing 90～70% is hydrogeneous 1.8～8%, also contains nitrogen, chlorine, sulphur and heavy metal compound.
Combustion method in float glass smelting kiln is: at first synthetic petroleum thick liquid is delivered to respectively under the port neck of glass melter both sides by pump, pressure is 0.8Mpa, and temperature is 40 ℃; Be assigned to the synthetic petroleum thick liquid of every spray gun branch road, through reversing purging valve automatic reverse control or artificial commutation control, enter into the synthetic petroleum thick liquid spray gun, with compressed air is atomizing medium, air pressure is 0.75Mpa, make atomizing medium form synthetic petroleum thick liquid mist torch, synthetic petroleum thick liquid mist torch enters on every side for the required air of synthetic petroleum thick liquid burning simultaneously; At last, the synthetic petroleum slurry drops is entered in the float glass smelting kiln 60 ℃ of heating mixes with air, first with water evaporates, volatile matter volatilizees and causes that the coke granule in the synthetic petroleum slurry drops fire burns then, up to after-flame.
This method is through research experiment repeatedly, realized that the combustion method of synthetic petroleum thick liquid in float glass smelting kiln produce float glass, is a major reform and breakthrough fuel used in the glass production process.
