Energy-intensive industries often involve complex industrial processes that consume vast amounts of energy and fossil fuels. Innovation efforts in this sector must seek to find solutions and technologies that can boost energy efficiency in these processes, which in turn will result in a more modernized and competitive industry.

At CIRCE, we work on developing tools that afford significant control over combustion processes and improve a series of aspects such as burner operation, ash disposal, etc. These improvements make the equipment run better, thus enhancing performance, while at the same time reducing fuel consumption and, consequently, its associated harmful emissions.

Within this field of knowledge, CIRCE also specializes in biomass combustion systems, where our capacities range from analysing combustion processes to designing and developing equipment for specific purposes. We also work on integrating these systems into others based on fossil fuels so as to steer the energy mix towards renewables.

  • CFD simulation

We are specialists in analysing combustion systems using fluid-dynamic simulation, which helps to enhance equipment efficiency and design while keeping emissions and soiling under control.

  • Image-based diagnosis in energy-intensive industries

CIRCE has developed two imaging tools intended to boost process efficiency in energy-intensive industries.


  • NOx emissions

We analyse the characteristics of combustion systems and propose solutions that help to lower nitrogen oxide (NOx) emissions to meet increasingly restrictive standards, bearing in mind the requirements of each system and the importance of not compromising production quality.

Reducing energy consumption and emissions in glass manufacturing


CIRCE has been working with Veralia to develop new solutions to reduce energy (i.e. fuel) consumption and contaminating emissions in furnaces in the glass sector by 3 to 5%. These solutions can also be exported to other sectors.

Diagnosing a cracking furnace in the petrochemical industry


CIRCE has been entrusted by DOW Chemical Ibérica to conduct an analysis, modelling and diagnosis on an ethylene production process, which could lead to financial savings of €3 million per year by identifying critical efficiency points.

Heat absorption system for Repsol industrial processes


CIRCE is working with Repsol and the TUPRAS refinery, along with other partners from the INDUS3ES project, to develop a new system to retrieve low-temperature residual heat and invest it in other industrial processes, leading to up to 20% fuel savings.
