Application of petroleum coke powder in glass furnace

Release date:2016-09-26 Author: Click:

If you want to know the characteristics of petroleum coke combustion in glass melting furnace, we must first understand the characteristics of the glass furnace. The furnace temperature, the flame length and the cleanliness of the flame of the glass melting furnace have strict requirements. The temperature in the furnace is generally maintained at about 1500 degrees Celsius. In order to ensure the whiteness of liquid glass and clean glass, glass melting kiln mostly low ash, high calorific value of heavy oil as the main fuel for heating; and heavy oil burning by high atomizing nozzle, fuel can be fully refined and exposed to the air, it can not only improve the fuel combustion efficiency, but also reduces the black smoke phenomenon, the the combustion adjustment is also more flexible. It can be used in glass melting furnace for oil fuel must meet the requirements of high calorific value, low ash, high burning rate and easy ignition, flexible adjustment of technology and process.

Calorific value of petroleum coke is higher, about 30 ~ 36MJ/kg, ash is very low, generally only 0.1% ~ 0.3%, the volatile is divided into about 10%, carbon content accounts for about 90%, the activation energy of the fuel is 151 ~ 167kJ/mol. Petroleum coke and heavy oil are very close to the hydrocarbon content, while the proportion of hydrocarbons in the fuel determines the calorific value of the fuel. Compared with coal, biomass fuel, coal water slurry fuel, calorific value of petroleum coke calorific value is very close to the heavy oil; on the other hand, petroleum coke and heavy oil are low ash fuel in petroleum coke ash is about 0.18%, and the heavy oil ash is about 0.001%, compared with coal and other fuel, coke stone easier to meet the process requirements of glass in the ash melting furnace.

From these data, we can see that the role of petroleum coke powder in the glass furnace is still relatively good.

Application of petroleum coke powder in glass furnace

Petroleum coke is a carburizing agent and accelerant. Today, to introduce the application of petroleum coke powder in glass furnace. Petroleum coke powder comes from their purchase of petroleum coke processing, has the advantages of low cost of some petroleum coke is a by-product of raw oil delayed coking unit in the production of light oil cracking under high temperature when the black or dark grey hard solid, with a metallic luster, components are 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 heat temperature. The higher the viscosity of feedstock oil coke slurry viscosity is high, thus reducing the viscosity of crude oil is an important means to reduce the coke slurry viscosity, viscosity is less commonly used in the production of oil slurry or medium temperature coal tar oil as raw material, and adding suitable amount of additives. In order to reduce the amount of iron to the introduction of machinery, high wear resistance of the grinding body, each link chute internal laying of UHMWPE wear resistant lining board.
