2 Ceneral data Output of the CHP plant Fuel Woodchips consumption Planned electricity production Planned heat production Decrease in CO2 emissions Efficiency 25 MWel / 49 MWth + scrubber 18 MWth (max) wood and peat up to sm3/year up to180 GWh/year up to 430 GWh/year ton/year up to 90 % (over 100% with FGC) Investment 72,2 m Staff 23 employees

3 Tallinna Küte : Tallinn DH network

4 Project Milestones Feasability study 2003 EIA report Main contracts signed Detailled land planning Investment decision Construction-permit Loan contract First foundation ready Start of boiler & turbine installation 01/ First fire in the boiler First steam to the turbine First synchronization of turbine Start of full load production

5 Project Expectations Very high efficiency Production of the renewable energy/electricity up to 180 GWh/year Very efficient reduction of the CO2 emission Power and heat cogeneration all year round Alternative supplier of the heat. Decreasing the dependence on natural gas. Increasing the reliability of the DH network. Decreasing the natural gas import Decentralization of the power generation and positive impact to the reliability of the electrical system Valuation of the low quality forests. Increasing the employment in rural areas Decreasing the water use and oil shale combustion in Narva powerplants Gentrification one of the most awful areas in Tallinn

6 Fuel supply - social and environmental impacts Biofuels reduce greenhouse gas emissions in comparison to fossil fuels Increasing stable demand of biofuels caused a boom on biofuel market. More value is added to forestry sector Additional investments are made into wood processing equipment This has encouraged new support schemes for forest and agriculure entrepreneurs Created new jobs and contributed to regional and rural development

7 Classical cycle with a steam boiler, a steam turbine and a generator Flue Gas Condenser (Scrubber) Combustion air Humidification system F G C boiler turbine G DH net Make up water

8 Fluidized-bed steam boiler NFBST: Power (MCR) Steam output 75 MW 28.2 kg/s Steam parameters: pressure temperature 110 bars 530 o C Main fuels wood chips, forest waste peat wood fuels + peat Fuel for start light fuel oil

9 Single-housing condensation (back pressure) extraction turbine Siemens SST 600 Number of bleeds 4 1. High pressure heat exchanger 2. Deaerator 3. Low pressure heat exchanger 4. District heating network heat exchanger Nom. exhaust steam pressure 0.27 bar Max. exhaust steam pressure 3.10 bar Number of blades lines 28 pcs Turbine control system TURLOOP S7 Generator rated power 25 MW Rotations frequency Steam turbine 6000 p/min Generator 1500 p/min

10 The scrubber enables flue gas cleaning and water vapour condensation by adding heat power up to 18 MW th. Water used in the scrubber is purified and after that used in the district heating network as make-up water.
