Abstract
The invention discloses a combustion method for petroleum coke powder. The method comprises the following steps: delivering petroleum coke powder to a burning gun by using compressed gas; and then mixing the petroleum coke powder with another path of oxygen and ejecting the obtained mixture for combustion by using the burning gun. The combustion temperature of the petroleum coke powder on a glass kiln can reach or approach the flame temperature of heavy oil combustion. The burning point of the petroleum coke powder is 600 to 800 DEG C, and the temperature of the glass kiln is up to 1500 to 1600 DEG C; after petroleum coke is ground into solid powder, the solid powder is injected into flame space of the glass kiln through gas conveying, is rapidly ignited and fully burns out, so combustion efficiency of the petroleum coke powder is improved, defects of glass caused by deposition of unburned petroleum coke powder in the prior art is avoided, and atmospheric contamination is reduced at the same time.
Description
Technical field
The invention belongs to kiln combustion field, be specifically related to a kind of petroleum coke powder combustion method.
Background technology
Glass industry is the industry of a highly energy-consuming, and in glass cost, fuel cost accounts for 30%-50%, and glass furnace is the maximum equipment of energy consumption in glass production line.China's glass production capacity has accounted for 70% left and right of global production capacity, but the technique of glass furnace practicality is still the technique that tradition falls behind, and pollution is large, energy consumption is high, cost is high.
Petroleum coke powder is the byproduct after the delayed coking of oil is refined, and is used for doing the utilization ratio that fuel can improve petroleum-based energy, is well suited for being applied in the highly energy-consuming fields such as glass production.Current petroleum coke powder glass furnace, with air, carry out combustion-supporting, because content of oxygen in air is low, make coke powder be difficult to fully mix with oxygen in kiln, thereby greatly reduce the efficiency of combustion of coke powder, unburnt petroleum coke powder can form defect along with tail gas is drained in atmospheric layer or is deposited in glass metal, airborne nitrogen reacts with oxygen under the high temperature of kiln simultaneously, generates nitrogen oxides pollution environment, increases energy consumption again.
Summary of the invention
The existing kiln of object of the present invention be take petroleum coke powder and is fired inconsumable problem during as fuel, and a kind of clean-burning method of petroleum coke powder that makes is provided.
It is as follows that the present invention realizes the technical scheme that above-mentioned purpose adopts:
Petroleum coke powder combustion method comprises, by pressurized gas, petroleum coke powder is delivered to burning rifle, then with after another road oxygen mix by burning rifle ejection, burns.
Further, described pressurized gas is air or Sweet natural gas.
Pressurized gas is used air to reduce costs, and discharges atmosphere pollution but kiln has a small amount of oxynitride; For the purpose of environmental protection, preferably use natural gas.
Further, the speed that described petroleum coke powder enters burning rifle is 10～400kg/h, and the flow of pressurized gas is 5～80Nm
3/ h.
Further, the granularity of described petroleum coke powder is 30～300 orders.
Further, by the petroleum coke powder of 1kg and 1.5～3Nm
3oxygen mix (while adopting air as pressurized gas, oxygen is herein the oxygen not comprising in pressurized air).
Accompanying drawing explanation
Fig. 1 is petroleum coke powder combustion schema of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further details.
Nm in the present invention
3be illustrated in 0 ℃, 1 gas volume (cubic meter) that standard atmosphere is depressed.
Embodiment 1
The petroleum coke powder that business is bought, through dehydration, makes its water ratio≤5%, removes iron in petroleum coke powder, then through grinding superfine powder, finally can make the granularity of petroleum coke powder reach nearly 300 orders, then carry out entering in petroleum coke powder storage tank after a deironing with electromagnetism with electromagnetism.
As shown in Figure 1, petroleum coke powder in petroleum coke powder storage tank is by weight-loss type feeding machine accurate-metering feeding coal, speed with 10 kg/h is sent into Venturi tube by double-spiral feeder, at Venturi tube inlet mouth, blasts pressurized gas (natural gas), and the flow of pressurized gas is 5 Nm
3/ h, under pressurized gas drives, petroleum coke powder is sent to burn robs front end, and combustion-supporting oxygen is delivered to burn by another road gas circuit and is robbed front end, and the petroleum coke powder that petroleum coke powder and combustion-supporting oxygen are pressed 1kg is to 3Nm
3the ratio of oxygen before rifle after pre-mixing, then be ejected in kiln and burn by burning rifle.
Embodiment 2
As shown in Figure 1, petroleum coke powder in petroleum coke powder storage tank is by weight-loss type feeding machine accurate-metering feeding coal, speed with 400 kg/h is sent into Venturi tube by double-spiral feeder, at Venturi tube inlet mouth, blasts pressurized gas (air), and the flow of pressurized gas is 80 Nm
3/ h, under pressurized gas drives, petroleum coke powder is sent to burn through piping robs front end, and combustion-supporting oxygen is delivered to burn by another road gas circuit and is robbed front end, and the petroleum coke powder that petroleum coke powder and combustion-supporting oxygen are pressed 1kg is to 2.5Nm
3the ratio of oxygen before rifle after pre-mixing, then be ejected in kiln and burn by burning rifle.
Petroleum coke powder temperature of combustion on glass furnace can reach or approach the flame temperature of heavy oil combustion.The burning-point of petroleum coke powder is 600-800 ℃, glass furnace temperature reaches 1500-1600 ℃, refinery coke is ground into after pressed powder, through gas, carry to spray in glass furnace flame space and can light rapidly and abundant after-flame, improved the efficiency of combustion of petroleum coke powder, avoid the defect that in existing method, uncombusted petroleum coke powder deposition causes glass, reduce topsoil simultaneously.
