Improved Emissions Inventories for NOx and Particulate Matter from Small Combustion Installations in Ireland - Stephen Morrin, UCD

  1. 1. <ul><li>Stephen Morrin </li></ul><ul><li>Supervisors: Dr. Will Smith & Dr. David Timoney </li></ul><ul><li>Wednesday 8 th September 2010 </li></ul>Improved Emissions Inventories for NOx and Particulate Matter from Small Combustion Installations in Ireland Wednesday 8 th September 2010
  2. 2. Project Objectives <ul><li>Estimate national NO x and particulate matter (PM) emission inventories from small combustion installations (<50 MW th ) : </li></ul>Project Objectives Industrial (1 – 50 MW) Residential (< 100 kW) Commercial (100 kW – 1 MW) Wednesday 8 th September 2010
  3. 3. What is an emission inventory? Accounts for all pollutants discharged to the atmosphere EU states – annual reporting requirements Formula used: SEAI Energy Balance EMEP Guidebook Well known Large variations in emission factor Doesn’t allow for operating condition Wednesday 8 th September 2010
  4. 4. Our Approach Real world duty cycle Wednesday 8 th September 2010 Use this in test rig in UCD Develop accurate emission factor relevant to an Irish duty cycle
  5. 5. Emissions Measuring Equipment also CO CO 2 Testo 350XL measures NO x Wednesday 8 th September 2010
  6. 6. Dekati Low Pressure Impactor Connect to Vacuum Pump Sampling nozzle Used to measure PM
  7. 7. DLPI Testo 350XL
  8. 8. Duty Cycle Data Wednesday 8 th September 2010
  9. 9. Typical Duty Cycle – Domestic Oil & Gas Wednesday 8 th September 2010 On: 4 min Off: 3 min On: 5 min Off: 3 min Cold Start: 28 min
  10. 10. Typical Duty Cycle – Domestic Pellet Wednesday 8 th September 2010 Off: 30 min On: 20 min Off: 25 min On: 22 min Off: 26 min Cold Start: 26 min
  11. 11. PM emissions Wednesday 8 th September 2010 Johansson, L.S. et al (2004). Atmospheric Environment , 38, 4183-4195 Boman, C. et al. (2005). Biomass and Bioenergy, 29, 258-268 EMEP Emission Factor: 76 g/GJ Johansson (2004): 16 g/GJ Boman (2005): 13 g/GJ
  12. 12. Overall PM concentration: Test 1: 18.6 g/GJ Test 2: 17.8 g/GJ PM Size Distribution Wednesday 8 th September 2010
  13. 13. Improved Emissions Inventories for NOx and Particulate Matter from Transport and Small Scale Combustion Installations in Ireland (ETASCI) <ul><li>Tim Grummell </li></ul><ul><li>Supervisors: Dr. Will Smith & Dr. David Timoney </li></ul><ul><li>Wednesday 8 th September 2010 </li></ul>
  14. 14. Project Objectives <ul><li>Develop up to date methods of estimating NO x and particulate matter (PM) emissions from road vehicles in Ireland. </li></ul><ul><li>Project future emissions of the vehicle fleet taking into consideration expected changes in vehicle technology and volumes of transport activity. </li></ul>Wednesday 8 th September 2010
  15. 15. Basic Approach <ul><li>Direct measurement from test vehicles </li></ul>How to measure the emissions factor? <ul><li>Modelling with use of existing experimental data </li></ul>Wednesday 8 th September 2010 Emissions = (Emissions Factor) X (Traffic Activity) ARTEMIS
  16. 16. Basic Approach <ul><li>Emissions Factor depends strongly on various parameters: </li></ul><ul><li>Fuel type (Petrol/Diesel) </li></ul><ul><li>Vehicle class (passenger car/truck etc) </li></ul><ul><li>Vehicle emissions class (Euro 4/Euro 5 etc) </li></ul><ul><li>Driving cycle </li></ul>Wednesday 8 th September 2010 Emissions = (Emissions Factor) X (Traffic Activity)
  17. 17. Wednesday 8 th September 2010 Model Inputs
  18. 18. Modelling using existing programs Relates: Level of emissions from a vehicle to Vehicle average speed COPERT ( Computer Program to calculate Emissions from Road Traffic) <ul><li>Average speed depends on driving cycle </li></ul><ul><ul><li>Correlates well with CO 2 and with fuel consumption </li></ul></ul><ul><ul><li>Does not correlate well for other pollutants 1 </li></ul></ul>Wednesday 8 th September 2010 1 Source: Hot passenger car emissions modeling as a function of instantaneous speed and acceleration (Joumard 1994)
  19. 19. ARTEMIS method <ul><li>European wide initiative </li></ul><ul><li>Road transport emissions model that can be applied at national and regional level . </li></ul><ul><li>Designed to overcome limitations of Average-speed models </li></ul>Assessment and R eliability of T ransport E mission M odels and I nventory S ystems Wednesday 8 th September 2010 Average Speed
  20. 20. Measurement of Drive Cycles <ul><li>Use </li></ul><ul><ul><li>On-Board Diagnostics (OBD) system that is build into most modern vehicles </li></ul></ul><ul><ul><li>GPS track logger. </li></ul></ul><ul><li>Download data to computer for post-processing and analysis. </li></ul>Wednesday 8 th September 2010
  21. 21. Project Current Work: Wednesday 8 th September 2010 <ul><li>Builds on work by Edward Casey (recent EPA-funded UCD PhD) </li></ul><ul><li>Development of the Kinematic software for use with TEXA OBD logger </li></ul><ul><li>Automation of data processing. </li></ul><ul><li>Collection of driving-cycle data. </li></ul><ul><li>Sensitivity analysis of the ARTEMIS software. </li></ul>
