Abstract
A viable solution for residual biomass exploitation to reduce the cost related to the biomass disposal and simultaneously create profit by electrical and thermal energy use is combined heat and power generation over the micro-scale of power (m-CHP) based on biomass gasification. The exploitation and improving of these systems were the main objective of the Italian project "PROMETEO - Production of electrical, thermal and cooling energy with m-CHP fueled by residual biomass", funded by the local Ministry of Economic Development (MISE). The present work shows an extended experimental activity based on a 20kW micro-cogeneration system as powered by different types of residual lignocellulosic biomasses briquettes in a demonstrative environment site identified in a waste management and storage plant in the Municipality of Mugnano, Naples, in the south of Italy. The m-CHP plant is made of a gasifier, a syngas cleaning circuit and a spark ignition (SI) internal combustion engine (ICE) connected to an electric-generator. The electrical output was meant to power the plant machines for the operations of waste storage. For both biomasses, tests were conducted over two consecutive days for the complete characterization of the system in low and medium load and in different spark ignition timing to assess the system sensitivity. The plant performance was investigated with a complete characterization of the syngas and tar compositions, main pollutant emissions and internal combustion engine analyses, aimed at the evaluation of the energetic and environmental efficiencies of the whole plant during the exercise. An analysis of the assessment of the air quality near the plant by evaluating CO, O3, NO2, C6H6 and PM10 concentration was also carried out. The ultimate purpose of the present work is the demonstration of the advantages of the employment of biomass-powered cogeneration systems in the Mediterranean regions, as part of biomass-to-energy chains suitable of being set in rural zones, within National Parks as well as to serve Municipalities having the need to dispose green waste from pruning and maintenance operations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
