2 Biomass heat and energy production Ing. Herbert Brenner Polytechnik Luft-und Feuerungstechnik GmbH 2

3 Our expertise in combustion of biomass: more than 40 jears experiance worldwide subsidiaries more than plants in operation export-rate rate approx. 85 % 3

4 World Energy Consumption Exajoule =10 18 J - sustainable development - biomass market of tomorrow will increase rapidly unknown geothermal solar energy new biomass wind water trad. biomass nuclear power natural gas oil coal and lignite Predicted World s s Energy Consumption (Shell-Study) Study) Source: Deutsche Shell AG Renewable energy sources Today s energy sources 4

5 BIOMASS COMBUSTION PLANTS with an individual boiler capacity of 500 kw to kw 5

6 Combustion types: hydraulic grate furnaces underfeed grate furnaces underfeed stokers 6

7 Kind of fuels: saw and plane shavings saw dust wood chips bark demolition wood grain remains poultry dung / horse dung other biomass 7

8 To produce heat and / or electricity for : district heating plants CHP cogeneration plants production heating processes 8

9 heat exchanger (boiler) for: warm water (up to 95 C) hot water (more than 95 C to 200 C) low pressure steam (up to 1 bar) high pressure steam (up to 36 bar) high pressure hot steam (up to 450 C, 63 bar) thermo oil (up to 320 C) 9

10 complete turn key installations, incl. fuel discharge fuel feeding system furnace boiler flue gas dedusting system control and regulation unit 10

11 electro-installation power generation units waterside installation incl. piping building for boiler house and fuel storage auxilary systems 11

12 Design and planning: Definition of plant parameters: pressures, temperatures, capacities, (warmwater, hotwater, steam, thermooil) Determine the annual heat consumption (min - max. capacities, annual operating hours table ) 12

13 annual heat consumption of district heating

14 Design and planning: AVAILABLE FUEL Accurate definition of the used fuel (min- /max. watercontents, size, ash contents, chemical analysis ) to fix the feeding and combustion system Determination of the ingredients of fuel as nitrogen, clorine, sulfur, o.s.o. to fix the flue gas cleaning system according to the valid emission levels 14

15 Design and planning: Nitrogen in the fuel: valid for level of NOx (NO2) : SNCR-plants, SCR- plants or other NOx reducing methods Chlorine: valid for HCl-value in flue gas and high temperature corrosion; Fix the heat transfer and max. temperatures in the boiler Sulfur: valid for SO2-value in flue gas, raises up the dew-point of the flue gas (corrosion) 15

16 Process engineering Definition of the proceedings according to the costs and economics Definition of the boiler parameters and fuel feeding / storage / and flue gas handling and cleaning. Choice of the flue gas cleaning system: multicyclone electrostatic filter bagfilter 16

17 Process engineering the heat-led application of a CHP plant are focussed to the heat requirements of the heat consumers. MW th heat led application (ORC, back pressure turbine) MW el heat / energy ratio For the power-led application of a CHP plant the focus is on the power production." MW th power led application (extraction condensing turbine) MW el heat / energy ratio 17

18 photosynthesis and carbon - cycle Energy from Biomass Sonnen- Energie CO 2 H 2 O Wood combustion doesn t contribute to greenhouse effect, because the disengaging carbon dioxide originated from combustion, will be bound by photosynthesis in growing up trees / plants. O 2 Heizhaus Therefore the CO2 balance is equalised. Biomass based heating plants use local, natural energy sources, which are renewable by photosynthesis. Holz Thermische Energie The use of wood energy contributes to the maintenance of forestry and landscape. H 2 O Mineralstoffe Asche 18

19 Clean combustion through adiabate combustion chamber with adjacent heat utilisation Advantage of Polytechnik: Low emissions (NOx, dust, CO, CxHy) Low fouling of adjacent heat exchangers Less expenses for cleaning / maintenance 19
