Biomass power systems

The continuous increase in the prices of fossil fuels and the need to achieve the set objectives in terms of CO2 emissions are two decisive factors for the assessment of all renewable energy sources as a priority option for heat production. Among these, woody biomass represents an interesting solution thanks to the increased availability of new heat generators operating with different fuels and technologies that ensure reliability and ease of management, all with a wide range of thermal power. Heat generators that function with wood fuel can be divided into three broad categories: wood, wood chips and pellets.
