4 FAQs about Exchange and Cooperation on Outdoor Photovoltaic Cabinets for Cement Plants

Can a conventional cement plant be used for solar thermal applications?

A conventional cement plant (Kotputli Cement Works (KCW), an UltraTech Cement Limited manufacturing unit) at Kotputli, Jaipur, Rajasthan, was investigated for solar thermal application. According to Indian Minerals Yearbook 2020, the plant produced 2.37 million tons, while the production capacity of the plant is 4 million tons.

Which approach is used for providing solar energy?

Approach used for providing solar energy includes the utilisation of a solar tower system with a solar reactor atop the solar tower or preheater tower in a conventional cement plant. Analysis considered thermal energy substitution ranging from 100% to 50%.

How to integrate CST Technology in a conventional cement plant?

Best approach to integrating the CST technology in a conventional cement plant is to use solar tower system with solar reactor at the top of the solar tower or preheater tower. Additionally, the use of non-conventional sources of energy in cement production reduces a lot of anthropogenic emissions to the atmosphere.

How effective is concentrated solar thermal in calcination process?

Depending on the thermal losses i.e., 15%, 30%, and 45%, the net conversion efficiency was 44, 56, and 69, respectively. Implementing concentrated solar thermal (CST) in the calcination process of the selected conventional cement plant could save 419 thousand tons of CO2 annually.
