The CRB multifuel biomass energy plant is coupled to a micro-turbine with a 100 kW electric net power, excluding the consumption of the plant. The micro-turbine can work in two different configurations: with natural gas or linked to a biomass plant. The efficiency of the system operating with natural gas is equal to 25%. For this energy plant the thermal power is equal to about 1 MWt and both in the natural gas configuration and in the biomass one, the alternator is equipped with the connection system to the parallel panel of the national electricity grid (resistive load bench by 100 kW installed on the roof of the CRB building). This alternator is able to allow the minimum energy consumption during the start-up and to have the electronic instrumentation for the adaptation of voltage and frequency of the electric current produced to the three-phase voltage and to the frequency (50 Hz) of the national electricity grid. In both configurations, the combustion chamber is configured to achieve the best combustion efficiency and to guarantee the minimum emissions in terms of NOx, CO and VOC (nitrogen oxides, carbon monoxide and volatile organic compounds). The present work presents a description of the components of the biomass plant installed to supply the thermal input to the turbine and some preliminary results obtained from the modeling of the components of energy valorization.

Abstract
The CRB multifuel biomass energy plant is coupled to a micro-turbine with a 100 kW electric net power, excluding the consumption of the plant. The micro-turbine can work in two different configurations: with natural gas or linked to a biomass plant. The efficiency of the system operating with natural gas is equal to 25%. For this energy plant the thermal power is equal to about 1 MWt and both in the natural gas configuration and in the biomass one, the alternator is equipped with the connection system to the parallel panel of the national electricity grid (resistive load bench by 100 kW installed on the roof of the CRB building). This alternator is able to allow the minimum energy consumption during the start-up and to have the electronic instrumentation for the adaptation of voltage and frequency of the electric current produced to the three-phase voltage and to the frequency (50 Hz) of the national electricity grid. In both configurations, the combustion chamber is configured to achieve the best combustion efficiency and to guarantee the minimum emissions in terms of NOx, CO and VOC (nitrogen oxides, carbon monoxide and volatile organic compounds). The present work presents a description of the components of the biomass plant installed to supply the thermal input to the turbine and some preliminary results obtained from the modeling of the components of energy valorization.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
