The invention discloses the processing method of on glass melter, using petroleum coke fuel; replace heavy oil with refinery coke; coal tar; Sweet natural gas; coal gas etc. use on glass melter; liquid or geseous fuel were different with use in the past; its outstanding feature is direct buring solid fuel on glass melter; with refinery coke through after mechanical mill becomes pressed powder; spray into glasses melting furnace flame space by gas delivery and mix also burning rapidly with the air or oxygen that enters glass melter; because refinery coke is ground to form pressed powder; and with gas the effect that flow media has played atomizing when carrying; mix and burning rapidly with the air or oxygen that enters glass melter after spraying into the pyritous glass melter; not only can make flame temperature and heavy oil combustion reach 1650-1730 ℃ equally; glassy product conforms to quality requirements; can reduce the glass production manufacturing cost greatly again; reduce heavy oil consumption; save petroleum resources, and help environment protection, have very high economic benefit and social benefit.
Description
Technical field
The present invention relates to Industrial Stoves fuel and use processing method, specifically relate on glass melter, use the processing method of petroleum coke fuel.
Background technology
At present, in the glass manufacturing, generally adopt the calorific value height, liquid fuel that ash is few (heavy oil, coal tar) or geseous fuel (Sweet natural gas, coal gas) are made glassy product, wherein using maximum is heavy oil, but because fuel sources such as heavy oil, coal tar or natural gas are in short supply, price is higher, has a strong impact on glass and makes economic benefit of enterprises.Refinery coke is the byproduct after the delayed coking of oil is refined, characteristics with golf calorific value, low ash, its price is lower again, is mainly used in carbon products such as producing Graphite Electrodes, anode mix, activated carbon at present, or acts as a fuel and be used for station boiler, cement mill etc.With refinery coke grind to form pressed powder directly on glass melter burning use and also not appear in the newspapers always.
Summary of the invention
The present invention seeks to have proposed a kind ofly to grind to form pressed powder with refinery coke and on glass melter, make fuel and use, can not only guarantee the glassy product quality, can reduce the processing method of glassy product manufacturing cost again greatly.
Of the present inventionly be: after refinery coke is become pressed powder through mechanical mill, spray in the glasses melting furnace flame space by gas delivery and to mix and rapid the burning with the air or oxygen that enters glass melter in the processing method technical scheme to be solved of using petroleum coke fuel on the glass melter.
At first, to refinery coke fixedly pulverized fuel replace heavy oil on glass melter, to use carrying out technical Analysis and economic analysis:
One, replaces heavy oil on glass melter, to use to refinery coke and carry out technical Analysis.Refinery coke replaces heavy oil to use on glass melter, reaches or the approaching same glassy product quality of heavy oil production of using, and its technical requirements is:
1, refinery coke temperature of combustion on glass melter will reach or near flame temperature 1650-1730 ℃ of heavy oil combustion, be analyzed as follows: the heavy oil calorific value is 9500kcal/kg, the refinery coke calorific value is 8500kcal/kg, burning 1.12kg refinery coke equates with 1kg heavy oil calorific value, can reach the combustion flame temperature 1650-1730 of heavy oil in glass melter ℃
2, refinery coke is the byproduct after the delayed coking of oil is refined, and contained ash is identical with heavy oil, so the ash of refinery coke can not impact glass quality.
3, the burning-point of refinery coke is 600-800 ℃, and the glass melter temperature can reach 1500-1600 ℃, and refinery coke is ground into pressed powder after gas delivery sprays into can light rapidly in the glasses melting furnace flame space and fully burning.
Two, it is as follows that the refinery coke grind into powder replaces the comparative analysis of heavy oil use cost:
Be example on 400 tons of/day float glass smelting kiln production lines, to use, see the following form:
| Project | Petroleum coke powder | Heavy oil |
| Calorific value (kcal/kg) | 8500 | 9500 |
| Deng calorific value consumption (kg) | 1.12 | 1 |
| Annual consumption (ten thousand tons) | 2.912 | 2.60 |
| Unit price (unit/ton) | 1200 | 2500 |
| Total price (ten thousand yuan) | 3494.40 | 6500 |
| Save cost (ten thousand yuan) | 3005.60 | 0 |
By last table analysis, replace heavy oil on glass melter, to use with petroleum coke powder, its technical and economy all is feasible, particularly the fuel economy cost is considerable.
The processing method step of petroleum coke fuel of using on glass melter of the present invention is:
Refinery coke through after mechanical mill becomes pressed powder, is sprayed into glasses melting furnace flame space by gas delivery, mixes with the air or oxygen that enters glass melter and burn rapidly.
Described mechanical lapping equipment can be a ball mill, vibrating mill, Raymond mill or other milling apparatuss.
Described refinery coke is the byproduct after the delayed coking of refinery crude oil is handled, powder size after milled processed is thin more, and combustionvelocity is fast more in glass melter, and is complete more, take all factors into consideration factors such as grinding power consumption, cost, to be advisable more than 90% by 200 mesh standard sieves.
Described gas delivery can adopt pneumatic transport equipment devices such as the air conveying pump of spiral, malleation air sealer, the air conveying pump of storehouse formula or air lift mud pump; Delivering gas can be used air, rare gas element or other gas, and gaseous tension can be provided by air compressor, rotary blower, paddle fan, compressed gas cylinder etc.Can directly spray into glasses melting furnace flame space by gas delivery refinery coke pressed powder, also can advance burner by gas delivery refinery coke pressed powder, in burner, feed pressurized gas and strengthen spraying into glasses melting furnace flame space after the atomizing, improve combustionvelocity and flame temperature.
Described glass melter comprises the glass melter of being with regenerator and not with the pure oxygen burning glass melter of regenerator.
The gas delivery petroleum coke powder sprays into glasses melting furnace flame space, can on the pipeline of a gas delivery petroleum coke powder, open two or more lateral, mounted valve is regulated the flow of each lateral on every lateral, spray into glasses melting furnace flame space then or deliver into burner, the pressurized gas that is admitted to burner is strengthened spraying into glasses melting furnace flame space after the atomizing.
The glass that uses petroleum coke fuel to make on glass melter of the present invention, product percent of pass reaches more than 90% after testing, and is identical with the glassy product qualification rate of producing with heavy oil.
The processing method that replaces heavy oil, coal tar, Sweet natural gas, coal gas etc. on glass melter, to use with refinery coke that the present invention proposes, liquid or geseous fuel were different with used in the past, and its outstanding feature is direct buring solid fuel on glass melter.Because refinery coke is ground to form pressed powder; and with gas the effect that flow media has played atomizing when carrying; mix and burning rapidly with the air or oxygen that enters glass melter after spraying into the pyritous glass melter; not only can make flame temperature and heavy oil combustion reach 1650-1730 ℃ equally; glassy product conforms to quality requirements; can reduce the glass production manufacturing cost greatly again; reduce heavy oil consumption; save petroleum resources; and help environment protection, have very high economic benefit and social benefit.
