Biomass Combustion in Poland present and prospective policy strategies - Adam Guła

  1. 1. <ul><li>BIOMASS COMBUSTION </li></ul><ul><li>in POLAND </li></ul><ul><li>present and prospective policy strategies </li></ul><ul><li>Adam Gula and Pawel Wajss </li></ul><ul><li>AGH University of Science and Technology , Krakow, Poland </li></ul><ul><li>and </li></ul><ul><li>The Krakow Institute for Sustainable Energy </li></ul><ul><li>presented at </li></ul><ul><li>The International Conference on Solid Biofuels </li></ul><ul><li>(ICSB 2011) </li></ul><ul><li>„ Beijing 11-12 November 2011 </li></ul>
  2. 2. RES in POLAND: <ul><li>Flat country - small hydro potential </li></ul><ul><li>Not much wind either </li></ul><ul><li>biomass is relatively abundant </li></ul>
  3. 3. <ul><li>So focus is on biomass, but </li></ul><ul><li>CONTRARY TO WHAT </li></ul><ul><li>MANY DECISION MAKERS </li></ul><ul><li>SEEM TO ASSUME </li></ul><ul><li>BIOMASS </li></ul><ul><li>is a </li></ul><ul><li>LIMITED RESOURCE </li></ul><ul><li>… by available harvest area, soil quality, climate ... </li></ul><ul><li>but also financial resources for investment </li></ul>
  4. 4. We have to remember that we need biomass primarily for food <ul><li>and also it for material (industrial) uses </li></ul>
  5. 5. <ul><li>When it comes to the energy use of biomass let us note that we can derive from it : </li></ul><ul><ul><ul><li>mechanical power (motor biofuels) </li></ul></ul></ul><ul><ul><ul><li>electricity or heat </li></ul></ul></ul>
  6. 6. <ul><li>we cannot satisfy all those needs simultaneously </li></ul><ul><li>at least in short or medium term </li></ul>we have to choose !!
  7. 7. <ul><li>co-firing of biomass with coal </li></ul><ul><li>(mainly in pulverized coal boilers) </li></ul>long distance transportation huge technical problems
  8. 8. illustration of the transportation problem:
  9. 9. Supply sources A hypothetical example ca 400 MW thermal power plant ca 5% of electricity from biomass
  10. 10. Źródło: Opracowanie własne 500 tons/day, i.e 50 trucks with 10 tonnes load per day times 100 km gives 5000 km/day (one way) i.e. Moscow – Lisbon return every day i.e. ca. 2000-3000 litres of Diesel oil + (LCA) energy embedded in truck maintenance & construction, maintenance of roads, etc gives about 25% loss of energy at the power station gate Moscow - Lisbon via PL 5100 km
  11. 11. examples of technical problems behind the power station gate:
  12. 12. <ul><li>Grinding : </li></ul><ul><li>The operation depends on the parameters of biomass </li></ul><ul><li>Residual biomass </li></ul><ul><li>current load grows 10-15% </li></ul><ul><li>The need of an extra mill </li></ul>
  13. 13. The adverse effect of co-firing of biomass on the heat exchanger in the boiler S&F Processes Slagging and fouling Due to high content of alkaline compounds in biomass Corrosion High temperature corrosion Chloride Chlorine compounds in biomass
  14. 14. Pipe of the secondary superheater X-ray pitting corrosion
  15. 16. POWER GENERATING COMPANIES WOULD NEVER DO THAT WERE THEY NOT HEAVILY COMPENSATED HOW IS IT DONE?
  16. 17. FOR EACH MWh of „ GREEN ELECTRICITY” POWER GENERATORS GET ABOUT 3 TIMES MORE THAN they get for a coal-based MWh t his is (ca. 70 EUR / MWh) this is a „hidden subsidy” which costs the Polish electrcity consumers ca. 700mln EUR/year !
  17. 18. <ul><li>This policy is increasingly criticised by experts </li></ul>
  18. 19. Central Europe Project 4BIOMASS opinion survey on a sample of 1221 biomass experts from: Austria, Czech Republic, Germany, Hungary, Italy, Poland, Slovakia and Slovenia www.4biomass.eu *Authors: Katharina Renner, University of Vienna (statistical analysis) Johannes Schmidl, Kerstin Schilcher Austrian Energy Agency Vienna, September 2011
  19. 20. Weighted answers to the question: Which kind of biomass use will be most important to achieve the environmental -goals in your country ?
  20. 21. <ul><li>CONCLUSION: </li></ul><ul><li>electricity generation from biomass </li></ul><ul><li>is NOT a good use of biomass </li></ul><ul><li>to achieve the environmental goals </li></ul>
  21. 22. <ul><li>The favoured alternative for countries with a climate similar to Poland is: </li></ul><ul><li>use biomass locally for heating </li></ul><ul><li>primarily in rural areas </li></ul><ul><li>(where it grows) </li></ul><ul><li>this will minimise the transportation needs create local jobs and </li></ul><ul><li>help develop rural development </li></ul>
  22. 23. <ul><li>The basic principle of biomass strategy should be: </li></ul><ul><li>use biomass first of all locally </li></ul><ul><li>only if there is a surplus </li></ul><ul><li>you may trade it </li></ul><ul><li>(preferably with close neighbours) </li></ul>
  23. 24. <ul><li>Thank you </li></ul>
  24. 28. Examples of applications Chrzelice 100 kW Location: Chrzelice ( southern Poland ) Boiler type: EKOPAL RM 30 (100 kW) Application: heating of two single-family houses
  25. 29. AGH, 180 kW
