Fortel Oy company involved in bio-energy business, created a ecological village at Kempele near Oulu. The ecological village consists of 10 houeses including the smart electric grid, a wind mill and a pilot gasification plant which produces Combined Heat and Power. The residential houses are demonstration area to create ecological homes which uses renewable energy like bioenergy and windmill.
The CHP plant uses wood chips as feedstock to gasify the wood or wood waste to produce wood gas in a gasifier (which are burn using fuel and O2). The wood gas basically consists of CO, CO2, CH4, H2, etc flue gases which are cooled using water and waste heat is recovered using heat exchangers, and the cooled gases are fed into a piston ICE using air to combust and to produce electricity. One Kg of dry wood to produce 1 watt electricty + 3 watts heat for district heating and warm water (at 65 deg C). The visit was really fantastic to watch a pilot scale CHP unit and people are warmly welcomed us and delivered a short presentation on the ecological village.
