Renewable energy

Production of new plant or modernization of your boiler to replace fossil fuels by the recovery of biomass, waste wood, CSR or RDF.

Forest biomass

2016 Brignoles: Power plant based on firing virgin biomass as well as recycled waste wood - Spreader stoker fired rotating grate for 66MWth input producing superheated steam at 96 bar 520° C feeding a steam turbine producing 168GWh per year – overall power plant performance> 32% efficiency with a reduction of 138,600 tonnes CO2 annual released into the atmosphere.

Agricultural derived waste

2016 Enterra Foggia (IT): Power Plant based on residues from locally produced agricultural crop such as olives, grapes and tomatoes – Spreader stoker fired combustion grate boiler with 43MWth capacity producing superheated steam 62 bar 420 °C for decentralized electrical production - 120,000 tonnes of waste recovered with a reduction in CO2 emissions of 58,000 tonnes per year.

Wood waste

2014 Robin Roussillon: Waste wood Type B & C plus waste paper rejects - Bubbling Fluidized Bed (BFB) combustion of 24MWth producing saturated steam at 40 bars supplying the chemical platform of Roussillon replacing coal - 68,000 tonnes of waste recovered with reduction in CO2 emissions of 56,000 tonnes per year.

2018 Chartres: Waste wood cogeneration plant - Bubbling fluidized bed combustion of 26.5 MW with production of superheated steam 72 bars 520 °C with external gas fired superheater- 58,000 tonnes of waste recovered with overall cogeneration efficiency> 75%.

Co-firing or conversion from coal with use of biomass

including the conversion of the 72MW 485 °C 60bar boiler from Poterne Unit to Grenoble
