  • Rura z przegrzewacza pośredniego pary wtórnej
  • Każdy metal podlega utlenianiu jednakże w pewnych warunkach proces ten może przechodzić bardzo gwałtownie. Odporność na utlenianie danego gatunku stali jest określana przez jego żaroodporność determinowaną stabilnością warstwy tlenkowej chroniącej metal przed gwałtownym utlenianiem (wykres Chaudrona). Stabilność warstwy ochronnej jest uzależniona przede wszystkim od temperatury, środowiska w którym się znajduje oraz od składu chemicznego stali co ma odzwierciedlenie w składzie chemicznym warstwy. W związku z powyższym każdy gatunek stali ma dopuszczalną temperaturę dla długotrwałej pracy [9] po przekroczeniu której następuje utrata własności ochronnych warstwy tlenków i gwałtowne utlenianie (korozja) metalu.

    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>
