10 Combustion Control Ignition Detection Logic Igniter Temperature Minimum Time Above Threshold Temperature 1 Nominal Igniter Operation. Ignition Threshold Temperature Igniter Ox And Fuel Valve Open, Spark On 3 Failure to Remain Above Threshold Temperature. Run Abort Sequence. 2 Failure to Reach Threshold Temperature. Run Abort Sequence. Maximum Time to Threshold Temperature Time

11 Handler Functions Handler Functions simplify code by allowing commands to be generated in multiple locations while actions are performed in one central location Handler Controls Cluster GUI Handlers

12 GUI Control Logic (Start Button Handler) Start Button Display Handler. Action? Enable Disable Lock No Action Button Disabled Property = 0 Set button color to green Start Button Display Handler.State = Enabled Start Button Display Handler.Action = No Action Button Disabled Property = 2 Set button color to red Start Button Display Handler.State = Disabled Start Button Display Handler.Action = No Action Button Disabled Property = 1 Start Button Display Handler.State = Locked Start Button Display Handler.Action = No Action

13 GUI Control Logic (Auto Start Switch = F) T Auto Start Switch? F Start Option Display Handler. State? Enabled Disabled Locked Start Button Display Handler.Action = Disable Start Option Display Handler.Action = Disable

14 GUI Control Logic (Auto Start Switch = T) Y Start Option = Igniter or Test? N Start Button Display Handler. State? Enabled Disabled Locked T Start Button? F Start Button Display Handler.Action = Enable Start Mode = Countdown Start Controls Macro Handler. Action = Lock Start Controls

16 Parallel VIs Parallel VIs used for Data Acquisition and setup windows Initialize References to Parallel VIs Strict Type Definition Maintains Organized List of Parallel VIs

17 Parallel VIs Starting Execution of Parallel VI

18 LTS-100 Laser Temperature Sensor Employs Tunable Diode Laser Absorption Spectroscopy (TDLAS) for Measurement of gas temperatures up to 4000 F Testing performed along 48 foot path at Ameren Sioux Station near St Louis, MO Processing Unit in Terminal Room

19 Laser Alignment System Interfaces to a Unisearch Associates LasIR TDL-based sensor Enables continuous beam alignment despite duct wall movement

20 Future Directions Continued Oxy-Fuel and Process Control system development Investigations into LabVIEW Real-Time / CompactRIO Integration of LTS-100 into Combustion Control System for closed-loop combustion temperature control

21 Discussion / Questions Industrial Combustion Control Hardware Selection - PLC vs PCs and NI platforms? Software Selection - Wonderware, C vs LabVIEW?
