BIOENERGY TECHNOLOGY: INNOVATION IN ACTION

Increasing bioenergy options and efficiency

AREVA is continuing to advance the standardization and efficiency of bioenergy plants by introducing new technologies to its energy production process.

COMBUSTION STEP GRATE

Able to burn various forms of biomass, ranging from dry wood waste to humid poultry litter, combustion step grates are a highly practical bioenergy technology. The step grate is also able to burn mixed biomass fuels, providing flexibility to use available biomass residues according to harvesting season.

The main advantages of the step grate include:

  • tolerates high moisture content,
  • lower emissions,
  • greater efficiency,
  • lower unburned material,
  • improved consistency of steam conditions,
  • flexible fuel options,
  • lower CO2 output.

Manufactured in Chennai, India, the grates are built with modular design, and have adjustable air flow, grate speed, and stroke of grate elements. These adjustable elements give biomass plant operators greater flexibility to achieve the most efficient burnout rates.

BIO COAL

The AREVA group, a major player in renewable energies, has announced in 2012,  the acquisition of a technology enabling the production of bio-coal. Based on the Thermya* torrefaction process, this unique technology, currently being deployed commercially, produces plant fuel from biomass which can replace fossil coal used in the production of thermal energy and electricity.

This operation enables AREVA to consolidate its position as a solutions provider for energy with less CO2. It is in line with the group’s strategy to broaden its offer in the field of renewable energies by placing a stronger emphasis on technology.

* The torrefaction (or depolymerization) of biomass is a thermo-chemical process aiming to eliminate water and alter part of the organic matter of biomass to break down its fibers. Torrefied biomass (or bio-coal) offers a number of benefits, including high energy density, hydrophobia, and increased grindability
