Problems solved by technology

Oil tar slurry is a kind of slurry fuel with good fluidity, and its combustion effect is close to that of heavy oil. However, stabilizers need to be added during the use process to avoid the sedimentation of oil tar slurry. The precision is not high, it is easy to cause fluctuations in glass quality, and the added stabilizer is easy to cause pollution to the glass liquid, so the scope of use is greatly limited

Embodiment Construction

[0021] The mass percent of petroleum coke powder in the oil tar slurry is: 25-35%.

[0022] The preferred mass percent of petroleum coke powder in the oil tar slurry is: 29-31%.

[0023] With 5000kg of oil coke slurry prepared each time, the amounts of heavy oil and petroleum coke powder are calculated as follows.

[0024] Formula 1: heavy oil 3550kg petroleum coke powder 1450kg

[0025] Formula 2: heavy oil 3500kg petroleum coke powder 1500kg

[0026] Formula 3: heavy oil 3450kg petroleum coke powder 1550kg

[0027] Process method and process:

[0028] The application of oil coke slurry without any additives in the regenerator cross-flame 450-ton float glass tank kiln is as follows:

[0029] Process the petroleum coke powder into a particle size of 500-600 mesh, add the processed petroleum coke powder according to the proportion of 30% by mass at a heating temperature of 90°C to a preparation tank equipped with heavy oil to configure oil coke slurry, and stir it mechanica...

Abstract

Oil coke slurry for a float glass tank furnace and a process thereof belong to the improved field of fuels for the float glass tank furnace, and the weight percentage of petroleum coke powder in the oil coke slurry is 25 to 35 percent. The process comprises the material preparation, the first compression, the first-stage filtration, the middle circulation, the second-stage filtration, the second compression, the middle storage, the third compression, the oil pressure control, the heating, the third-stage filtration and the control of a spray gun. The petroleum coke powder with 400 to 600 meshes is added in an oil coke slurry mixing tank which contains heavy oil according to the weight percentage of 29 to 31 percent, the mixture is fully stirred by a mechanical stirring device, the stirring temperature is 88 to 92 DEG C, the combustion efficiency of the oil coke slurry is close to the heavy oil under the premise of not adding any additives, a heavy oil control system and a pipeline are utilized to achieve the precise measurement and the control of the whole control process, thereby ensuring the stability of the whole control process.

Description

technical field [0001] The invention relates to an oil tar slurry for a float glass tank kiln and a process thereof, and the invention belongs to the field of fuel improvement for a float glass tank kiln. Specifically, it is an application of an oil tar slurry without any additives in a float glass tank kiln. Background technique [0002] At present, the domestic glass industry is affected by energy shortage and rising oil prices, so that the heavy oil fuel commonly used in the glass industry accounts for an increasing proportion of glass manufacturing costs. In order to not only ensure the normal melting quality of glass, but also achieve the effect of reducing fuel costs, the glass industry has been looking for alternative fuels. Oil tar slurry is a kind of slurry fuel with good fluidity, and its combustion effect is close to that of heavy oil. However, stabilizers need to be added during use to avoid the sedimentation of oil tar slurry. The process is complicated, and it...
