Can a solar power system save CO2 in cement industry?

Concentrated solar power system is designed for cement industry. Substitution of required thermal energy ranging from 100% to 50% is studied. 7600 heliostats with 570 ha land required for 50% conventional energy replacement with solar energy. Selected conventional cement plant could save 419 thousand tons of CO 2 annually.

Which cement plant is used for solar thermal application?

Location and DNI availability of the investigated plant A conventional cement plant (Kotputli Cement Works (KCW), an UltraTech Cement Limited manufacturing unit) at Kotputli, Jaipur, Rajasthan, was investigated for solar thermal application.

How to run solar reactor for calcination of raw material in cement production?

Solar and thermal energy needed to run the solar reactor for the calcination of raw material in cement production using a heat balance equation is as follows: Solar incident power on the solar reactor (Gonzalez and Flamant, 2013): (7) Q S R = Q r x n + Q h r m 1 − % Q l The mirror surface needed: (8) S m i r r o r = Q S R η S F D N I

Can a solar-heated rotary tube reactor be used for limestone calcination?

Abanades and André (2018) designed and experimentally tested a solar-heated rotary tube reactor for limestone (CaCO 3) calcination at 1000 °C. Receiver of the reactor is a cavity type for absorbing solar radiation from a concentrating system. Solar reactor can be successfully used for CaCO 3 calcination involved in either lime or cement production.
