The company, highly specialized in the planning, realization and commercialization of advanced working unit for energetic transformation of biomasses and waste to generate power at distributed level, gas filtration systems, engineering aspects of plants for energy and materials recovery from waste, has developed and tested a technology for energetic transformation of biomasses based on the gasification, able to satisfy both energy and heat requirement (up to 1.5 MWt) of small and medium industries, agricultural farm, tertiary companies.
The technology tested on pilot plant facility, is based on down-draft fixed bed technology and introduces two innovations in the gasification process. The first one related to the first step of internal pyrolysis and the other one regards the third step of thermal cracking. These options permit both an increasing of cold gas efficiency and improve the characteristics of
product gas. In order to increase the energy conversion efficiency; gas filtration efficiency as well as simple and full automatic operation, plant is also optimized. The basic plant is primarily composed of a feeding unit, gasification unit and the gas filtration unit. The feeding unit comprises of a storage bin, an elevator, a secondary storage drier and an isolation bunker. Gasifier is a fixed bed down draft type realized with austenitic steel and refractory. The gas filtration unit can have different arrangement, the basic one (adopted for using gas in reciprocating internal engine) is composed of cyclone, pre-coated bag filter, water/oil scrubbing and de-humidifier/re-heater. The control system permit a full automatic control with limited man-power necessity. The family plant are available at three different power level 150, 600, and 1200 kWt.
A pilot plant having a size of 150 kWt has been realized and tested at different power level, the product gas characterization show an a Low Heating Value in the range of 4800-5200 kJ/Nm3, a gas composition in the range %H2=13.6-16.2, %CH4=1.6-1.9, CO=15.0-18.8, CO2=13.9-18.2, N2=47.8-50.0.
Innovative Aspects:
The biomass gasification technologies developed for distributed application are based on "fixed bed gasifier" type, the society has been introduced some innovations in the gasifier arrangement in order to permit both an increasing of cold gas efficiency and improve the characteristics of product gas.
The others innovative aspects are:
- development of modular and standardized systems;
- development of products appropriate for both micro and distributed power -generation with thermal and electric cogeneration;
- development of competitive systems with the conventional distributed power generation systems;
- the positioning in market niches, predominantly focusing attention on "end user".
