Power Flame DC-4-AS Sequence Overfire Draft Control

Power Flame

The Power Flame DC-4-AS Sequence Overfire Draft Control is a powerful system that is engineered to control, monitor, and express combustion chamber pressure. In the event it’s needed, the Power Flame DC-4-AS Sequence Overfire Draft Control can automatically shut the burner down if it detects inadequate pressure for a predetermined amount of time. This innovative and compact system combines all of the components of flue gas monitoring, draft control, and safety: 

  • High performance microprocessor for accurate draft control
  • Damper position readout
  • Draft range signal for monitoring
  • Electronic draft reading
  • Optional flue gas temperature reading
  • Optional flue gas temperature alarm
  • Low draft or high pressure cutoff switch

Power Flame DC-4-AS Sequence Overfire Draft Control Standard Package

The Power Flame DC-4-AS Sequence Overfire Draft Control works to control and monitor either negative or positive combustion chamber environments. It includes a range of standard features that seamlessly work together to provide a simple operator interface and accurate control. The standard system incorporates:

  • Low draft cutoff with adjustable time delay,
  • Auto-open damper selector switch,
  • Adjustable starting draft,
  • Damper actuator assembler, and
  • Controller/pressure LED readout

You can further customize your Power Flame DC-4-AS Sequence Overfire Draft Control based on the needs of your facility with optional features like a linear damper actuator assembly and stack temperature monitor with digital LED display. 

Power Flame DC-4-AS Sequence Overfire Draft Control Standard Functions

The unit can be field configured through the easy-to-use front panel push buttons (decrease, increase, enter, right, left escape) and with simple jumper changes on the programmable logic controller. Draft control logic functions include:

  • Adjustable start
  • Pre- and Post-purge
  • Sequencing

The liquid, two-line crystal display broadcasts the sensor values and parameter alarms in engineering units. Because draft pressure is presented on the draft controller, it doesn’t require separate mechanical gauge and piping. The three-mode selector switch (open/close/auto) allows the damper to be positioned manually. It comes standard with Modbus communications.

Features and Benefits of the Power Flame DC-4-AS Sequence Overfire Draft Control

Draft control is critical to both water tube and fire tube boiler applications. Boilers with stack heights of 25-30 feet can benefit from proper draft monitoring and control because it can:

  • Improve combustion efficiency
  • Bolster heat transfer
  • Improve flame stability
  • Reduce room heat loss
  • Improve flame retention
  • Reduce pilot light failure

Whenever the Power Flame DC-4-AS Sequence Overfire Draft Control system is applied, you can dramatically improve the efficiency. A few key features and benefits of this system include:

  • Saves fuel and improves safety
  • Multiple draft control functions
  • Optional flue gas temperature indicator/control
  •  Electronic draft gauge
  • Modbus Serial Communications
  • Field configurable for all control & monitoring functions
  •  Menu-driven setup
  • Low draft/high pressure cutoff switch
  • Economical: long-term returns on low Initial investment
  • CUL & UL Approvals pending
  • Input/output diagnostic LED’s
