Description

Contrive uses the term “parametric” to illustrate that the operation of Q2 can be tailored to virtually any burner technology or application through the modification of parameters. While the use of parameter settings in burner controls is common, the Q2 takes this to the next level by providing the ability to modify parameters and behavior at each stage of the burner cycle. Activating and assigning a predefined duration to each stage allows you to define which fuel or air valves to turn on, to choose which inputs to control, and predefine an actuator position that controls the air or gas flow.

This nuanced approach makes it simple to configure Q2 to manage:

  • Single stage direct ignition up to 350kW (1.2MM BTU/hr)
  • Multistage (unlimited capacity)
  • Intermittent or continuous operation
  • On/off or modulating
  • Flameless
  • Staged gas
  • Staged air
  • Recuperative
  • Regenerative
