Project Description

Decarbonization : 56 tons of CO2 saved taking into account an emission rate of 0.201 kgCO2/kWhth consumed

Energy gain : 280 MWhth saved per year

Location : Meymac (19) – New Aquitaine – France

Client : Ceramics and development – Tegulys

Sector : Ceramics

Needs – customer requests :

The feasibility study carried out for the Céramiques et Développement – Tegulys site in Meymac aimed to study the recovery of high temperature waste heat coming out of a kiln in order to recover it in the factory dryer.
The study also had to take into account a potential gain in productivity by studying the installation of a pre-cooking chamber fed exclusively by the available waste heat. As a result, the firing cycle would be reduced and would make it possible to carry out more furnace cycles per year.
This part will be refined in a second study, the results presented take into account the current production and a complete recovery of the waste heat towards the dryer.

Project progress :

  • Analysis of the fatal heat source of the baking oven via a measurement campaign
  • Analysis of the energy needs of the dryer via the operation of its burner
  • Following this characterization, Eco-Tech Ceram sought the most relevant solutions to satisfy energy needs as much as possible. As this is out of phase with the heat source, a storage solution was chosen. Given the temperature levels (> 500°C), the Eco-Stock® solution was chosen. Two solutions with or without taking into account the customer’s productivity gain were presented to the customer via a complete report.

Eco-Tech Ceram achievements :

  • Identification of cooking cycle periods where the fatal heat is greater than 500°C
  • Sizing of an Eco-Stock® solution : storage capacity of 1300 kWh
  • Aeraulic study on the smoke system network: sizing of the fans
  • Thermal study on the smoke system network: validation of calculations with insulator specialists
  • Study of the energy repercussions on the various stations of the factory following an increase in production
  • Plant-wide energy and environmental balance sheet
  • Economic study of the solution and financial arrangement
  • Design of the solution and implementation of the proposed solution
  • Site monitoring, commissioning and performance monitoring
