Description

BTN40-55GC E BLU Series Low NOx Gas Burner covers low-NOx gas burner applications for boilers and process heat systems, spanning the 45 to 480 kW output range with modulation and electronic modulation configurations.

Operating Modes

Modulation; Electronic modulation

Key Features

  • Air and gas are mixed in the combustion head for stable low-NOx combustion.
  • Combustion air and burner head settings can be adjusted to tune combustion parameters.
  • The hinged body opens naturally for easier inspection and maintenance.
  • A servomotor adjusts minimum and maximum air flow for the firing stages; when firing is suspended, the damper closes to reduce furnace heat loss.
  • GC variants use a cam-driven servomotor to adjust air and fuel supply together, while GE variants use two servomotors for separate control.
  • A flange and high-temperature insulation pad are used for boiler connection.
  • Combustion air intake includes a throttle damper.
  • Single-phase motor drives the fan.
  • Flame supervision uses an ionization electrode and ultraviolet photocell detection.
  • Electrical protection rating is IP40.
