BurnerMate TS Components

System Composition 10” Touch Screen Operator Interface Accurate Servo Actuator Integrated Oxygen Analyzer!

Touch Screen Operator Interface Fully Integrated Touch Screen…

Touch Screen Operator Interface  Monitor and control boiler operation, setpoints, and process data from one convenient display  Commissioning activities are laid out in an easy to follow step-by-step procedure, eliminating the need for knowledge of controller menus and programming languages

Touch Screen Operator Interface Alarm banner, Silence button, and Navigation Auto/Manual Control Real time boiler management data

DCS-III Programmable Control DCS-III Controller…

DCS-III Programmable Control  The DCS-III is a state-of-the-art, boiler- focused programmable logic controller  The large I/O quantity, small sub-panel foot print, intuitive “Blockware”, redundant memories, and built-in industry standard communication allows the DCS-III to be integrated into complex boiler control systems with a minimum number of external components

Easy Commissioning *The “Learn Mode” feature allows multiple F(x) block input vs. output profiles to be entered simultaneously with a push of a button! “Store” button to simultaneously store the firing rate, oxygen and burner air flow rate value into the appropriate F(x) blocks

BurnerMate TS Advanced Communication …

Internet, Web Site Access  A standard WEB Browser provides remote monitoring and operation  Custom software is not required  Historical Alarm and event data can be imported to spreadsheet applications such as MS Excel

Intranet Communication  The ethernet communication port is easily assigned an IP address and connected to a facility wide network  Remote monitoring, control and data collection is available via a standard WEB Browser  Building Automation Systems and SCADA Systems are interfaced via industry standard MODBUS Ethernet communication

Integral Oxygen Analyzer DCS-III with "Z" Option Board Connecting Cable ZP-xx Oxygen Probe Calibration Gas Input Grade Level Connection By Others Power Supply *No separate analyzer, one less item to mount Field replaceable probe Only one conduit to stack.

Integral Oxygen Analyzer  Proven Reliable  Sensing element has been proven reliable in 100s of installation over the last 10 years  No Reference Air  The probe uses ambient air as a reference.  Competitors use instrument air and run the risk of element cracking due to water  Automated, menu driven pushbutton calibration.  Fully automatic calibration package available.

BurnerMate TS Control Strategies

Fully Metered System

 This control strategy with oxygen trim and variable speed fan control offers the best opportunity to save fuel and electrical cost with a control system upgrade  This strategy measures both the fuel flow and the combustion air flow  PID control is used for both fuel and air flow control, assuring the accurate maintenance of fuel and air flow setpoints

Parallel Positioning System

 This control strategy includes up to five (5) servo channels, allowing independent control of fuel valves, air and fuel gas re-circulation dampers  The fuel-air ratio is established and adjusted by use of a “soft” function curve of fuel valve vs. damper position  Parallel positioning enables “tighter” fuel-air ratio control, which improves boiler efficiency  Combining this control method with oxygen trim and variable speed fan control offers substantial cost savings for a fast payback

Single Point Positioning System

 This control strategy mechanically links the fuel valve, air and flue gas control dampers to a single actuator  Generally, the fuel valve has a characterizable flow versus position relationship that is used to establish the fuel-air ratio over the range of modulation  This method is recommended when the boiler size or service hours do not justify addition of a VSD

BurnerMate TS Auxiliary Controller / Flame Safeguard

Integrated Auxiliary Controller  Draft Control – Stable & repeatable draft control is essential for efficient boiler operation. This is especially important for boilers with induced Flue Gas Recirculation (FGR) Nox reduction.  Feedwater Control – Single element, two element or three element feedwater control may be provided. Water column blowdown is prompted and logged to ensure proper maintenance.

Flame Safeguard  Features  The Flame Safeguard System provides the proper burner sequencing, ignition and flame monitoring protection on single burner, automatically ignited oil or gas fired boilers.  The system uses a fail-safe, “de-energize” to trip design. Upon the loss of system power the fuel safety shutoff valves are automatically closed and ignition components are de-energized.

BurnerMate TS SCADA System Integration

SCADA System Supervisory Control And Data Acquisition:  Windows XP based workstations  Programmable Controller based combustion control hardware  Up to 31 I/O per controller  Touch Screen interface can be used as backup control station if the workstation, or communication network breaks down  “Service Manual” mode can be used as backup control station if the Loop Controller fails
