Study of Decreasing Energy Consumption in Ironmaking System
The iron and steel industry is one of the largest energy-consuming manufacturing sector both in industrialized and developing countries. In China, the energy consumption of iron and steel industry accounts for about 10%-13% in total energy consumption, and BF-BOF route is a dominating process route. Ironmaing system takes a part view in BF-BOF route, shares of 60%-70% energy consumption in iron and steel works, containing sintering, coking and blast furnace process. It is of great significance to develop a method to analyze potential energy saving possibilities in the steel industry. In this work, a model is developed using the mass and energy balance equations and applied to a special iron and steel works in China. Factors of energy consumption influence is analyzed with the status of the special ironmaking system. The main purpose is to save coke because its consumption is the predominating item of the input energy both in the blast-furnace plant and in ironworks. Furthermore, the promotion of energy saving technologies, such as TRT, PCI, residual heat recovery of hot blast stove, high efficiency dry-type deduster for BFG, etc. will be analyzed for energy saving and environmental protection in the future.
