Carbon dioxide emissions derive, above all, from iron ore reduction that takes place in blast furnaces and sponge iron plants; emissions consequently follow the production fluctuations of ore-based steel. Emissions also come from the use of fossil energy in e.g. reheating and heat treatment furnaces. About one half of the steel industry's total energy consumption (process coal

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of

In the pulverizing system for an alumina sintering processes, the hot air temperature to dry the coal powder using the remaining heat for cooling clinker is low and varies frequently. This can easily causes either the coal powder over coarser or the decrease of the mill output. In this paper, an intelligent setting method for mill load is proposed and presented, which consists of an

Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by; a. Residence time of the material in the mill chamber. b. The size, density, and number of the balls. c. The nature of the balls (hardness of the grinding material) d. Feed rate and feed level in the vessel. e. Rotation speed of the cylinder. Several types of ball mills exist. They differ

After milling micro powder coal will be transported to the boiler through a round tube. The crushed coal is conveyed by means of the primary combustion air at the side of the boiler furnace. The carbon powder is introduced into the coal mill through a central inlet pipe where gravity is used to cause the coal to the coal mill base, in which the grinding table and heavy rolls coarse powder

Coal dust explosion blast wave exiting mine portal. There are two main types of coalmine explosions: methane and coal dust. Methane explosions occur when a buildup of methane gas contacts a heat source and there is not enough air to dilute the gas level below its explosion point. Likewise, fine particles of coal dust in the right concentration that contact a source of heat can also be

The mill reject loss depends on the amount of pyrite in coal and the mill operating condition. The rejects by the mill do have a heat value which is accounted as mill reject loss. This can be minimized by properly maintaining the mill cleanaces and operating at the optimal condition. The carbon-monoxide loss is due to combustion not being fully completed. However small these
