3 WHAT ARE OUR ACTIVITIES? 1. CAPITAL ENERGY EQUIPMENT 2. PROVIDE COMBUSTION SOLUTIONS 3. LEADERS IN LOW EMISSION TECHNOLOGIES 4. OPTIMIZED ENERGY EFFICIENCY AND UTILIZATION 5. SERVICE EXISTING INSTALLED EQUIPMENT

4 Business market focus includes Pulp & Paper, Oil sands, SAGD, Oil & Gas Thermal Power Generation and Utilities Air Quality Improvements, Reduced Green House Gas Emissions Energy Efficient Liquid Heating Thermally Efficient Refractory Linings High Temperature Metal Operations

5 What does Inproheat Manufacture? Gaseous Fuel Trains Thermal Oxidizer Air Heaters Submerged Combustion Liquid Heaters Refractory Throats for Fired Boilers and Heaters, Specialty Pump Skids

6 Energy Systems Group Our Business Partners Schroeder Belco Technologies Corporation Coen Company, Inc. KSB Pumps Inc. Nooter Eriksen Inc. Sigma Thermal Crane Environmental Swep International Tranter Paratherm Corporation Rentech Boilers Pick Heaters, Inc. Copes-Vulcan

7 Why Combustion System Retrofits? To ensure maximum combustion efficiency Reduce Energy costs Highest availability of Steam production at all times For compliance with changing emission standards Minimize Maintenance

8 What defines a successful upgrade? Addressing existing operational issues as observed by operators and maintenance Develop a well defined Engineering Scope of Work that clearly outlines and identifies all aspects of the project. The Devil is in the Detail! Execute credible and practical demolition and installation procedures Utilize proven materials of construction that will maximize the life span

9 Package Boiler Burner Retrofit Replace Existing Dated Burner Register with Low Nox Design Single Burner Capacities from 65 to 250 MM Btu/hr Typically existing Wind box can be reused Refractory Throat Shapes will also change Depending on duration of outage, Refractory Throat System may vary from field installed plastic to pre cured cast assembly

10 Burner Register Installation

11 Throat tub prep for Refractory Installation

12 Precast and Cured Throat Installation Lifting Lug

13 Delta-NOx / Bitumen Firing Ready applied to SAGD OTSG s

14 Potential Low NOx Solutions 76 ppm - Delta-NOx with No FGR 49 ppm - Delta-NOx with Minimal FGR 49 ppm - QLN with No FGR 20 ppm - QLN with Minimal FGR <10 ppm- the above with SCR & ULN

15 Hearth Burner Installation Natural Gas 30 MM Btu/hr 15 ft. flame length Objective: 1. Promote controlled and more rapid Cold Boiler Start up 2. To stabilize grate while firing wet hog 3. Minimize firing of existing high load burners 4. Provide assured heat input as required

16 Air Cooled Hearth Throat on Side Wall

17 Burner Wind box and Register Assembly

18 Complete Burner with dedicated Combustion Air Fan

19 Recovery Boiler Start Up Burners Natural Gas 4 X 28 MM Btu/hr Retractable Pilot Retractable Main Visible High Intensity Electrode Spark Objective: provide assured availability to bring the Recovery Boiler on line from Cold Start Existing Burners were not reliable and contributed towards increased downtime and increased costs

20 Original Fixed in place gas Burners

21 Original Burner View Port New Burner View Port Retractable Pilot Ignition Main Start Up Burner

22 New burner with integral port cleaner

23 Even with Improved retract capability fired burner ends exhibit high fouling Burner tips condition and scanner lens must be monitored to ensure highest possible availability. The Devil is in the Details
