1. Integrating flow measurement into ABB CEMS Steve Donnelly - March 2013

2. ABB Company Confidential CEMS Standards Flow metering Stack emissions subject to legislation for many years Output in KTons/year has always been required, but standards did not specify how to establish Flow measurement sometimes but not always used – many mass flows are calculated New standard will give requirements – and gives guidance on - flow metering techniques

3. ABB Company Confidential CEMS Standards Europe 2001…LCPD, WID ……..IED EN 14181Relevant European standard for on-going quality assurance of CEMS EN 15267-3 Performance specifications and test procedures for CEMS Must now measure the mass of pollutants released, not just the concentration EN ISO16911 Will specify the requirements for flow measurement

4. ABB Company Confidential FPD580 StackFlowMaster First choice for CEMS flow metering Uses proven Torbar averaging pitot flow metering technology. Assures compliance with new European & US EPA regulations Optimises plant running hours Simplifies installation Reduces cost of ownership Integrates into new and existing CEMS

5. ABB Company Confidential FPD580 StackFlowMaster Why use Averaging Pitot for Stack Measurement Low installation costs Max two stabbings to be cut into stack (only one if not end supported version) Available in a variety of materials to suit different processes Multi-port instrument resistant to effects of changing flow profiles Reliable, long term solution no moving parts no electronics within stack Low risk of failure in the primary element

6. ABB Company Confidential High Pressure Low Pressure Static LP pressure point Outer Impact Tube Differential Pressure Output Connected to DP Measuring Instrument How Averaging Pitot Tubes work The ABB averaging pitot: Multi-port meter across full diameter ‘auto-traverses’ Resultant differential pressure is proportional to the square of the volume flow rate Measures the mean fluid velocity without the need for traversing Upstream HP sensing holes HP Inner Tube LP Inner Tube

7. ABB Company Confidential FPD580 StackFlowMaster Profiled flats around the downstream hole define the flow separation point stable pressure area at downstream tapping more constant coefficient at high velocities very wide turndown Provides a highly stable flow signal Low Pressure Tube Torbar Edge - Better performance and stability Profiled flats

8. ABB Company Confidential FPD580 StackFlowMaster Easier handling for large diameter stacks probes above 5 metres are in two pieces with centre coupling simplifies shipping and handling; may simplify installation Torbar Edge – Easier handling

9. ABB Company Confidential FPD580 StackFlowMaster Why choose StackFlowMaster? Averaging pitot tube technology approved under the new standards EN15267-3 & MCERTS approval satisfies QAL1 & QAL3 requirements. Optional automatic zero/span checks no physical user intervention required Supply with ABB CEMS analyser enables purchase of complete package from single supplier/manufacturer Enables CEMS upgrades to meet the new legislation Robust for long term use minimal maintenance.

10. ABB Company Confidential FPD580 StackFlowMaster Torbar advantages Easy to install Requires only a simple one - or two - stabbing insertion Robust meter with a long service life Reduces risk of expensive failures Stronger construction than those with special profiles Offers good quality, stable measurement Due to unique sensor profile Special end support designs give greater integrity From ABB's many years of experience

11. ABB Company Confidential FPD580 StackFlowMaster FPD585 Flow Probe with Automatic Interface Torbar probe specifically designed for stacks 25 or 60mm diameter optional integral RTD Multivariable transmitter DP & absolute pressure measurement with temperature input remote mounted in interface unit Automatic interface unit 3 versions MCERTS pending for automatic zero/span versions

12. ABB Company Confidential FPD580 StackFlowMaster FPD585 Automatic Interface Variants Automatic zero/span checking option No external equipment to be connected Checks at the push of a button Optional Enclosure Heater For ambient temperatures below 0°C Purging Recommended for particulate concentrations > 30mg/m 3 and up to 300 mg/m 3

13. ABB Company Confidential FPD580 StackFlowMaster Purging Cleans probe ports using pressurised air Enclosure contains multivariable transmitter for volume or mass flow measurement Enclosure contains sequencing controls/valves for automatic (regular) purging or on-demand purging Purge Air Contaminated Flue Gas Purge Air Data

14. ABB Company Confidential FPD580 StackFlowMaster Key aspects of Installation Location:- Requirements for upstream lengths of stack, expressed in terms of the actual stack internal diameter D Minimum upstream straight length is 8D Minor obstruction (sample probe) OK if > 3D upstream 8D

15. ABB Company Confidential FPD580 StackFlowMaster ABB supplies complete CEMS SOx, NOx, CO, HCl, HF, NH3… O2 combustion Dust Mass flow Data acquisition and reporting

16. ABB Company Confidential FPD580 StackFlowMaster Benefits Wide range of stack temperatures suitable for stack gas temperatures up to 1200°C Wide range of stack applications Incinerator plants, power generators, refineries, metals processing, cement plants, crematoria Up to 8m diameter Handles solid contaminants Up to 300mg/m3 automatic or manual purging of probe ports available

17. ABB Company Confidential FPD580 StackFlowMaster Benefits Handles corrosive contaminants 316L, 321H or alloy 625 sensor Hastelloy C transmitter diaphragms, PTFE seals; optional 316 transmitter housing Easier installation in large diameter stacks two piece probes with centre coupling Simplifies handling, transportation, installation Simplified QAL3 compliance Automatic option for tx span check No external equipment required Simple to size and specify Intuitive software for selection, sizing and coding Auto-updating facilities
