Technical FAQs 4

How much energy does a cement plant need?

Another challenge lies in the higher energy demand for induction-based systems. As discussed, process modeling suggests that an electrified cement plant using an induction-based pre-calciner may require a total energy input of 4.75 GJ per ton of clinker, which is higher than the 3.7 GJ/ton required by conventional fossil-fuel-fired plants 174.

Why is energy storage important for cement manufacturing?

Without robust energy storage solutions, fluctuations in power availability could introduce instability into cement manufacturing operations. Additional challenges such as the need for substantial grid infrastructure upgrades, and the geographic mismatch between renewable energy availability and industrial hubs exist.

What are the possible waste heat recovery pathways in a cement plant?

Engin et al. 221 evaluated the possible waste heat recovery pathways in a cement plant and identified: (1) kiln exhaust gases, (2) hot air from the cooler stack, and (3) radiation from the kiln surfaces, as heat loss sources that can be considered for heat recovery.

Can dry process cement plants generate electricity?

Beshore et al. 220 analyzed the dry process cement plants in the USA to identify the possible waste heat recovery sources and develop TES based systems that can be used to generate electricity.
