If you want to understand the characteristics of petroleum coke combustion in glass furnaces, you must first understand the characteristics of the following glass furnaces.
The glass furnace has strict technological requirements for the temperature, flame length and flame cleanliness in the kiln, and the temperature in the furnace is generally maintained in the range of about 1500 ℃.
In order to ensure the cleanliness of glass liquid and the whiteness of glass, most of the glass furnaces use heavy oil with low ash and high calorific value as the main heating fuel.
And the heavy oil combustion uses the high efficiency atomization nozzle, the fuel can be fully refined and in contact with the air, which not only improves the fuel combustion efficiency, but also reduces the black smoke phenomenon, and the combustion adjustment is more flexible.
Therefore, the replacement fuel which can be used in glass furnace must meet the technical and technological requirements such as high calorific value, low ash content, easy ignition, high burnout rate and flexible adjustment.
The calorific value of petroleum coke is about 30 ~ 36MJ, the ash content is very low, generally only 0.1% ~ 0.3%, the volatile content is about 10%, the carbon content is about 90%, and the activation energy of the fuel is 151~167kJ/mol.
The hydrocarbon content of petroleum coke is very similar to that of heavy oil, and the proportion of hydrocarbon in the fuel determines the calorific value of the fuel.
Compared with coal, biomass fuel, coal water slurry and other fuels, the calorific value of petroleum coke is very close to that of heavy oil.
On the other hand, petroleum coke and heavy oil belong to low ash fuel, the ash content of petroleum coke is about 0.18%, while the ash content of heavy oil is about 0.001%. Compared with pulverized coal and other fuels, stone coke is easier to meet the technological requirements of glass furnace.
From these data, it is not difficult to see that the role of petroleum coke powder in glass furnace is better.
Application of Petroleum Coke Powder in Glass Kiln.
Petroleum coke powder is a carburizer and a combustion promoter.
Today, I would like to introduce the application of petroleum coke powder in glass kiln.
The first source of petroleum coke powder is that it buys petroleum coke for processing, and the advantage is that some petroleum coke powder is a by-product of cracking the raw oil of delayed coking unit to produce light oil at high temperature, which is a hard solid of black or dark gray.
It has a metallic luster and is composed of hydrocarbons.
With the increase of the proportion of petroleum coke powder, the viscosity of oil coke slurry can be reduced by properly increasing the mixing temperature.
The higher the viscosity of raw oil, the higher the viscosity of coke slurry, so reducing the viscosity of raw oil is an important means to reduce the viscosity of coke slurry. In production, the slurry or medium temperature coal tar with low viscosity is generally used as raw oil, and an appropriate amount of additive is added at the same time.
In order to reduce the amount of mechanical iron, the wear resistance of the grinding body should be high, and the ultra high molecular weight polyethylene wear resistant liner should be laid in each link of the chute.
