GREATER EFFICIENCY IN THE PRODUCTION CYCLE AND LOWER PRODUCTION COSTS
Electricity from micro-turbines to supply almost all the plant’s energy needs
Founded in the early 1960s, La.So.Le. EST is now a leader in Italy and Europe in the wood flour and wood chip sector for a wide range of industrial applications. One of the crucial steps in the production of wood flour is the drying process, which removes all moisture from the finished product to ensure that it is ready for sale on the market.
The wood flour that La.So.Le EST produces requires an air-drying process at 300°C (572°F) that consumes 1.2 MWth. This is why La.So.Le EST’s managers sought to increase the efficiency of the process: the solution turned out to be a cogeneration plant for the direct use of flue gas. The cogeneration plant is part of a wider project to modernise the production plant, which includes the installation of a new technical flour dryer. The application consists of a Capstone C600S turbine powered by natural gas. The fumes coming from the Capstone turbine are mixed with air at room temperature and sent to the air vein burner installed inside the dryer.
