2 July 11, 2006 Overview European Test Method European Test Method Emissions Standard Emissions Standard Technology Technology Effect on Competition and Innovation Effect on Competition and Innovation

3 July 11, 2006 EU Standard EN Adopted 1999 Adopted 1999 Solid Fuel Boilers Up to 300 kW ( 1 MMBtu) Solid Fuel Boilers Up to 300 kW ( 1 MMBtu) Applies to fossil and biogenic fuels Applies to fossil and biogenic fuels Coal, logs, pellet, chips, etc Coal, logs, pellet, chips, etc Automatic and hand stoked Automatic and hand stoked Construction Standards, Test Method and Emission Standard Construction Standards, Test Method and Emission Standard

4 July 11, 2006 EN Test Method Two Firing Rates Two Firing Rates Nominal and 30% load Nominal and 30% load 50% load allowed for hand stoked models 50% load allowed for hand stoked models Logwood Fuel Logwood Fuel Can be Soft Wood or Hard Wood Can be Soft Wood or Hard Wood Net (lower) calorific value (waterfree) Net (lower) calorific value (waterfree) Hardwood – 18,000 kJ/kg Hardwood – 18,000 kJ/kg

5 July 11, 2006 EN Test Method Parameters Measured Parameters Measured CO 2 or O 2 CO 2 or O 2 CO CO Organic Carbon (OGC) Organic Carbon (OGC) Dust (Particulates) Dust (Particulates) NOx when applicable NOx when applicable Efficiency Efficiency Ratio of delivered useful heat output to heat input Ratio of delivered useful heat output to heat input

8 July 11, 2006 EN Test Method Passing Grade Varies by: Passing Grade Varies by: Boiler Class: 1, 2 or 3 Boiler Class: 1, 2 or 3 1 = dirtiest; 3 = cleanest 1 = dirtiest; 3 = cleanest Boiler Size Boiler Size Fuel: Biogenic v. Fossil Fuel: Biogenic v. Fossil Stoking: Manual v. Automatic Stoking: Manual v. Automatic

9 July 11, 2006 EN Emission Limits

10 July 11, 2006 EN Efficiency Requirement Measured and calculated similar to ASTM Measured and calculated similar to ASTM Varies by size, stoking and boiler class Varies by size, stoking and boiler class Feed Method 10kW200kW Hand-stoked Class 3 73%83% Hand-stoked Class 1 53%62%
