ENERGIZE PANEL PRODUCTION
ORC MODULES
Turboden’s ORC modules are providing energy efficiency in wood-based panel production, says Alessandro Guercio, Turboden’s biomass sales and business development manager, who also reports the latest project win at Spanish PB producer Tableros Hispanos

ood-based panel production is an energy demanding process, both for
heat and power. Particleboard and OSB production need heat mainly for drying wood particles while MDF needs heat for drying wood fibres and also for steam production to the refining process.
Although some natural gas is still occasionally used, the main primary source of energy for heat production to drying process is biomass, in the form of waste wood such as sanding dust, panel scraps, branches
and low-grade wood not suitable for panel production.
On the other hand, the electricity demand
is commonly supplied by the electricity grid, exposing the producer to electric grid price variations a well as carbon footprint. Renewables such as solar and wind are spreading in all territories and applications, but natural unpredictability of these sources doesn’t fit with the steady and continuous demand of the production process. The implementation of combined heat and power (CHP) systems is the right solution
to reduce the power demand from the electricity grid through on site renewable electricity generation. A biomass-fired CHP system converts the
heat coming from a biomass combustion into electric power for own consumption and useful heat mainly for drying processes. The drying technology plays an important role in maximising the integration with CHP systems. In particleboard and OSB production, belt dryer technology is the best solution to maximise the CHP integration, having a belt dryer fully compatible with the
