As a new type of fuel, blue charcoal coke surface is more and more widely used in the steel industry due to its low volatile matter and blast furnace injection characteristics. This article will introduce the characteristics, injection methods, and application effects of coke surface to help readers understand the advantages and application prospects of coke surface in steel production.
1. The characteristics of blue charcoal coke surface.
Blue charcoal coke surface is a fuel with high carbon content and low volatile matter, and its appearance is similar to that of coal, but it has a higher fixed carbon content and lower volatile content. In the ironmaking process, the addition of coke surface can improve the accuracy of furnace temperature control and reduce exhaust emissions, while reducing the coke ratio and fuel ratio, and improve the economic benefits of iron and steel enterprises.
Second, the blast furnace injection mode.
In order to give full play to the advantages of blue charcoal coke surface, blast furnace injection has become an important technical means. Driven by high-pressure air or steam, the charcoal coke surface is sprayed into the blast furnace in powder form, which can be better mixed with molten iron and improve the efficiency of ironmaking. At the same time, the injection method can also reduce the crushing and loss of the coke surface and reduce the production cost.
Third, the application effect.
1.Improve ironmaking efficiency: The addition of blue charcoal coke surface can improve the temperature and purity of molten iron, which is conducive to improving ironmaking efficiency. At the same time, the powdered blue charcoal coke surface is easier to mix with molten iron to improve the quality of ironmaking.
2.Reduce exhaust gas emissions: Blue charcoal coke surface can reduce the coal dust content in the blast furnace, thereby reducing the dust and sulfur content in the exhaust gas and reducing environmental pollution.
3.Cost reduction: The use of blue charcoal coke surface can reduce the coke ratio and fuel ratio, and reduce the cost of ironmaking. At the same time, the use of injection mode can reduce crushing and loss, and further reduce production costs.
Fourth, the prospects.
With the continuous improvement of environmental protection requirements and the adjustment of energy structure, as an environmentally friendly and efficient fuel, blue charcoal coke surface will play an increasingly important role in the steel industry. In the future, with the continuous progress of technology and the promotion of application, blue charcoal coke surface will be more widely used in steel production, bringing more economic and social benefits to iron and steel enterprises.
In short, as a new type of fuel with low volatile matter and blast furnace injection, blue charcoal coke surface has obvious advantages and application prospects. In iron and steel production, the rational use of coke surface can improve ironmaking efficiency, reduce exhaust emissions, reduce production costs, and bring more economic and social benefits to iron and steel enterprises.
