Coke is an important raw material in the steel industry, and its quality directly influences the smelting of iron and steel. To improve coal quality and reduce coal blending costs, we need to predict the coke quality and optimize the coal blending scheme. In this paper, we propose a modeling and optimization method based on the characteristics of the coal blending and coking process.

How does CHP work? A conventional power plant makes electricity by a fairly inefficient process. A fossil fuel such as oil, coal, or natural gas is burned in a giant furnace to release heat energy. The heat is used to boil water and make steam, the steam drives a turbine, the turbine drives a generator, and the generator makes electricity.

The first one is blending in coal beds. In this method, blending takes place during reclamation with homogenisation at transfer points. The advantage of this methodology is that blending takes place at coal handling plant (CHP) transfer points. However, this process has disadvantages as the entire coal needs to be stacked first and CHPs are ...
