4 Insights in Optimal Boiler Room Controls Presented by Steve Connor September 18, 2013

5 Overview Today s Key Drivers Energy Conservation Emission Control Reduced Operating Costs Integration & Operation 5

6 Answering the Drivers

7 Energy Conservation O 2 Trim Control Transmitters and Sensors O 2 Loop Controller O 2 Probe Analyzer Servo Servo FUEL 7

8 Energy Conservation Draft Control Draft Loop Controller Stack Draft Transmitter Stack Draft Damper 8

9 Energy Conservation Hydronic System Control 9

10 Reduced Operating Costs Variable Speed Drive Control Energy Savings VSD Loop Controller Variable Speed Drive Control Burner Blower 10

11 Reduced Operating Costs Data Logging Maintains Last 100 Alarm Points 11

12 Emission Control Control Strategy Impact NO x Reduction Turndown Combustion Efficiency 12

13 Integration & Operation PLC vs Loop 13

14 Integrated Control System Burner Management Combustion Control Fuel Air 14

15 Burner Management System Sequence C.C. power and modulating motor energized Limit line and low fire switch Pre-ignition interlock Blower motor & terminal B in mod. motor Purge to High Fire and proving switch made (30 second purge timing 4 air changes) Running interlocks proven Purge to Low Fire and proving switch made Trial for Pilot and Flame Proven Main Valve Energized and Flame Proven Release to Modulation Any Burner Related Alarms 15

16 Integrated Control System Burner Management Combustion Control And Sub-Systems Fuel Air Traditional Jack Shaft Control Parallel Positioning w/cross Limited Feedback Control O 2 trim FGR Damper Control Variable Speed Drive on Burner Blower Motor Draft Control Feedwater control Lead lag control Full Metered Control 16

17 Firing Rate Signal From Boiler Controls Mod Motor Single Jack Shaft Control Common Shaft and Linkage Connections and Control Mechanical Adjustable Cam FGR Valve (If Used) Fuel Valve Combustion Air Burner Blower 17

18 Single Jackshaft or Single Point Positioning

19 Parallel Positioning: Fuel Air Ratio Control Required for Low NO x - around 30 ppm and below PP Loop Controller Burner Blower Servo Servo Servo FUEL 1 FUEL 2 FGR Servo 19

20 Economizer Control Economizer Loop Controller Stack Temperature Less waste out the stack Cooler Water In Heated Water Out Economizer By- Pass (if used) Diverts flue gas around economizer on low flue gas temps Flue Gas From Boiler Outlet 20

21 What It Takes To Accomplish This Solution Concept: An Individual Control Loop Controller Requires Individual loop controllers Separate control panel Interface wiring for BMS Firing Rate Control Fuel-Air Ratio Control O 2 Trim Relays and timers Extra wiring Expert tuning Draft Control VSD Control Economizer Control 21
