1. Compiled by:Tim Bessex Contributions:Prosper Ogonga, Martin Kalberer Dated: July 2008 The Impact Cylinder Turning Waste to Energy

2. » Exponential increase in fuel costs –No sign of slow-down! –100k tonnes waste incineration (claimed to) = 10k tonnes coal » Landfill space extremely limited » Green lobby gathering even more pace » Regulations and costs in waste management increasing » Commercially viable businesses are being created –Investment forecast: 37% increase over next 5 years –Est. 500 plants in Europe: 200 more planed over next 5 yrs The Growing Popularity of Waste-to-Energy

3. » Incineration of waste generates heat to produce steam to drive a turbine » Excess steam can also be ‘exported’ » Widely considered as a clean, reliable and renewable form of producing energy Waste Incineration / Thermal power plant (WI/TPP)

4. Waste Incineration / Thermal Power Plant (WI/TPP) Advantages : » Efficient removal of waste - waste is ‘renewable’ » Reduce demand for land-fill » Reduce cost of waste transportation » Ash by-product can be used in construction » Best method to eliminate methane gas emissions » Substitute and compliments energy from fossil fuels » Reduce combustibles volume by 90% hence reduce pollution Disadvantages: » Initial investment is very heavy » High operating costs » Technology applicable only if certain requirements are met » Legal regulations are complex and cumbersome » Complexity of processes requires skilled staff » Debate over efficiency / ROE and environmental effects

5. Boiler Efficiency can be DIRECTLY linked to ASH removal from Boiler mechanism The Waste-to-Energy Process

7. The Norgren Technology

8. » High impact energy delivered to ‘pestles’ by the Norgren cylinder. » The impact cylinder effectively cleans boiler exchanger – ‘In Process’ » Control panel clearly displays operation / functionality » Reliable operation » Safer operation » Adjustable impact energy < max 90 J (1-7bar) » Easy to service and maintain, reduced damage of pestles » Feedback available – remote monitoring » Specific impact zones can be created » Lower initial cost » Lower cost of ownership » Single Acting – fewer valves Customer Advantage – New Norgren Impact Cylinder

9. » MK1 system currently built at Alpen » Existing use in Switzerland / Austria / Germany Impact Cylinder with flange mounting

10. New Balterswil MK II

11. Balterswil MK II

12. » Impact cylinder, single acting (SPCH080003) » Duplex 3/2 valve, V22 series valve island system –2 impact cylinders are controlled by one duplex valve » Operating pressure 1-7 bar » Air preparation » Also consider Buschjost dust management valves as overall sales proposition » PLC Added Value – Impact Cylinder

13. » Assume 500 plants in Europe alone » Impact points per boiler – 30 - 50 » Boilers per plant – 3 - 10 » Potential per plant – 90 – 500 » If we were to retrofit only 20% of them –30,000 cylinders in Europe in the retrofit market alone » PLUS.. The rest of the world » PLUS … Targeting the preferred route of the OEMS Potential Volumes

14. » Soot Blowers –Air or Steam » Mechanical systems – Falling Hammer » Ball-bearing bombardment » Electrostatic charges » Explosions » Cross-over competition (areas of similarity) –Roll car systems –Electric impact cylinders » SMC » Nucon - India Competitive Technology

15. » VonRoll Falling Hammer System

16. » Examples Baumgarte & Clyde Bergemann Roll Car Solutions

17. 1.Attractive and growing Norgren focus sector Johannes Quinders 2.Heavily weighted to a limited number of key global players Foster Wheeler, Alstom, Hitachi, Babcock & Wilcox, Riley Power 3.Technology performance directly affects system performance 4.Excellent spread across OEM, End User and MRO business 5.Great opportunity for Added Value sales, Air prep, valves etc.. 6.Growth opportunities in all of Norgren key global zones The Norgren ‘Fit’
