In December 2015, Intercem was awarded a contract by Lafarge-Holcim for the turnkey supply of a hot gas system for a coal mill at a cement plant in Chekka, Lebanon. By realising this project, energy costs during operation for the cement plant will be consequently reduced and the specific labour need will be optimised.
This project is already the second contract for such an applications between Lafarge-Holcim and Intercem. In 2013 a hot gas system was realised in a cement factory in Jordan.
The new hot gas system in the coal mill plant in Chekka connects the preheater with the coal mill and comprises a hot gas duct with a length of 360 m and a diameter of 900 mm. The process data of the hot gas outlet of the heat exchanger are of 18 500 Nm3/h at 400°C.
Besides diverse ducts, a cyclone, a process fan and several control dampers, compensators, the complete instrumentation and automation, and a new recirculation duct with two control dampers at the existing vertical coal mill were supplied.
The turnkey scope of supply and services included:
The turnkey handover to the customer is planned for 4Q2016.
