3. SUSTAINABLE ENERGY IN KOŠICE REGION Recent situation in town Moldava nad Bodvou List of present boiler houses:  Boiler House K3 power capacity 5,1 MW, fuel Natural Gas - Kogeneration unit 0,15 MWe 0,23 MWt  Boiler House K4 power capacity 8,5 MW, fuel Natural Gas  Boiler House K7 power capacity 4,0 MW, fuel Natural Gas Supplied heat year 2007:  Production of heat 76.000, GJ  Central heating 48.300, GJ  Hot using water preparation 21.700, GJ  Production of electricity power 1.067, MWh

4. SUSTAINABLE ENERGY IN KOŠICE REGION Biomass plant in town Moldava nad Bodvou with technology of burning an wood chips Key-stone of the project:  Fuel switch from nature gas to biomass  Fossil biomass fuel ( consumption 9.500, ton/yr)  Power capacity 2x2.5 MW  Estimated production of heat energy 65 000 GJ Asset: Price stabilization Utilization of the regional fossil biomass fuel Reduction of CO2 ( green house gasses)

5. Wood chips are burnt in special incinerators with 87% efficiency of burning at the maximum power output of the boiler. The non-homogeneous composition of wood chips and the fluctuations in humidity require a stabilized operation system of the incinerator with the consumption of 300-400 kg of wood chips per hour of operation system for each MW of heat power.
