A small Romanian research company developed an installation for cogeneration by transforming biomass in gases. It is an ecological and efficient solution: by using 1.5 kg of biomass 1 KW/h electric energy and 1,3 KW/h thermo energy are obtained. Type of partner sought: research institute for technical cooperation or end-users for commercial agreement with technical assistance.
In the total of renewable energies (solar, wind, biomass and hydraulic), for the Europe zone, the energy from biomass represents about 60%. Transforming biomass in gases is a very efficient possibility, from an energetic point of view, to use the wastes from agriculture (straw, corncob, scopes from sun-flower, corn stalks, etc), from forest and from wood processing (wood chips and dust). It's a complex process that finishes with cogeneration of electric and thermo energy. Generally, such an installation uses many steps as follows: - The transformation of biomass in gases. - The gases are filtered and cooled.¬† - The gases are used in a motor (especially adapted for it). - The motor is used to produce electric energy or to pump water for irrigations or also for the motion of a camion. In the figure below a fix installation for transforming biomass in gases is represented; it can be realised to produce electric power from 200 KWh to 3,000 KWh. The wood materials (wood chips anddust, straw, corn cob and stalks, sun-flower scopes, etc.) are inserted in the bin feed. The obtained gas contains big quantities of ashes and charcoal dust; for this reason the gas is passed through a cyclone gas washer, which realises a rough filtration. The resulted gases have a high temperature: 400-600 Celsius grades. By introducing these at this temperature in a motor, the coefficient of admission is reduced and also the obtained power; so from the cyclone filter the gases are passed through an absorber cooler having water inside. The gases are refrigerated and the water heated. The hot water can be used for domestic or industrial purposes (house heating, warm water, timber drying in furniture factories, etc.). The obtained gases still contain important quantities of charcoal dust, 0.15-0.18g/stere, with dimensions till 400 mm. These gases are passed through a fine filter made from ceramic materials. This type of filter must fulfil two important requirements: - A very good filtration. - A good penetration, so that the gases passing through have enough pressure to assure a good coefficient of admission in the motor.†Finally the gases produce the engine motion and the motor acts an electricity generator.
Innovations and advantages of the offer:
Innovative aspects and the advantages of using biomass for co-generation are as follows:†- It is a very efficient solution: by using 1.5 kg of biomass 1 KW/h electric energy and 1,3 KW/h thermo energy are obtained. - It is an ecological solution. - The investment costs are recovered in 3 years and the normal usage life of installation is 30 to 40 years.
