Polygeneration plant, fueled with biomass from various sources and with rated power included between 30 kW and 200 kW, including a plurality of specialised modules, the modules being at least one first module for loading and drying the biomass; at least one second gasification module suitable for producing the syngas starting from the biomass; at least one third module for automating and controlling the polygeneration process associated to the plant. The polygeneration plant includes at least one fourth module including at least one fuel cell, the fuel cell being of the SOFC or MCFC, PEMFC, PAFC, AFC type.

The disclosure relates to a burner for burning combustible material in the form of a comminuted wood product, especially fine material, with (a) a combustible material feed for supplying the combustible material, (b) a screw conveyor for conveying the combustible material, (c) a combustion zone, wherein the screw conveyor is arranged to convey the combustible material (18) from the combustible material feed (20) to the combustion zone, (d) an air feed for supplying air to the combustion zone, and (e) a burner mouth for leading combustion gases out of the combustion zone. According to the disclosure, a compacting zone is provided, which is configured behind the combustible material feed and in front of the combustion zone in the direction of material flow (M) of the combustible material, wherein an auger of the screw conveyor and the compacting zone are preferably designed to compress the combustible material in the compacting zone.
