The company FCB Charpentes, in the Pas de Calais, is specialized in the manufacture of traditional frames, glued laminates and wood frames. It wants to invest in a new 100% wood boiler, and use the wood waste from its activity as fuel. Indeed, the current heating system for manufacturing premises is dual-fuel fuel oil and wood is no longer sufficiently efficient and requires significant maintenance. In addition, the particularity of the activity of manufacturing beams for structural use lies in the application of a resin-hardener mixture, requiring a temperature of 20 degrees. The boiler with a power of 490KW will heat the workshop and dryers for wood, or 2,762 m2.
