For instance, solar energy is difficult to store, and many kinds of biomass are not suited for combustion, in spite of the fact that they have high energy contents. We describe and industrial size system, which has the goal of overcoming some of these limitations by combining solar- and biomass power. This is achieved by roasting residual biomass by means of hot air provided by solar power only. The solar power is collected by three “Linear Mirror” solar concentrator, they are designed to achieve high efficiency also at northern latitudes. Each one is equipped with an innovative solar-air heat exchanger. The hot air is delivered to a roasting device filled with humid residual biomass. We report the performance of this system from a first commissioning run. The system is intended to help create a closed-cycle economy by means of transforming waste biomasses to a high-quality combustible.展开更多

In this paper, a solar-air heat exchanger of new conception is presented and tested together with a Linear Mirror II. The heat exchanger surface is selective with respect to direction and position of light absorption and emission and once heated by the Linear Mirror II, can reach an air temperature of up to 230°C.展开更多

The setup uses only the thermal solar energy provided by a system of reflecting mirrors (Linear Mirror II) to heat a selected agro-waste biomass, such as wheat straw. At the end of the pyrolysis process, solar carbon with a high energy density (around 24 - 28 MJ/kg) is produced from a biomass with an energy density of 16.9 MJ/kg. The perspectives for a future industrial application of this setup are also discussed.展开更多
