An applied 'Energy System' (ES) to produce energy by wasted biomass (Part one)

摘要

The research was funded by "Operative National Plan - European Capital for Regional Development" (PON-FERS 2007-2013, Industry 2015). Authors considered the Sicilian Little and Middle Enterprise (LME) producing wastes from operational processes as like woody chips, wood shavings, shells of hazelnut or almond and so on. A previous survey carried out on a consistent sample of Sicilian LME showed that electrical power required by operational processes ranges substantially around three main values (250/500/635 kW_e) and research was addressed to obtain previous values of electrical power by process of conversion of biomass. People takes in consideration the exploitation of biomass through pyrolysis process since it produces syngas usable as fuel in gas-turbine of CHP plant, bio-oil and bio-char too, both of them able to supply thermal energy to many section of expected plant. The whole paper describes the general plane of research (three sections of loop of plants) and particularly guidelines for: 1. calculus of sizes of biomass stockpile storage (storage and drying - first section); 2. design of equipments of pyrolysis process and exhausts treatment (pyrolysis process - second section); 3. design of cogeneration system (CHP techniques - third section). The final result of research will specify too the economical decreasing of operational costs of LME and the remarkable environmental benefits arose by exploitation of biomass. For room reasons, the part one of paper describes the generalized characteristics of research and results of calculations to design drying and storage section.
