1. Introduction. Rated at 2 MWh e /capita [1], annual electric energy consumption is rising globally at a fast pace, as energy needs grow with increasing population.Cement and coal power plants are the prime consumers of solid fossil fuels. Coal fired power plants supply 37% of global electricity (~2500 GW) [2] using about 9 …
Cement industry is characterized by sizeable energy demand which accounts for about 110kWh (3.75 thm) per ton of cement in modern plants. Industry impacts heavily also on CO2 emissions.
Beside technological improvements, the composition of raw materials and the final product may also influence energy consumption. As shown in Fig. 1 after the crushing process, pre-blending and grinding, the raw materials are calcined to produce the semi-final product called clinker. The calcination process uses approximately 24% of the …
