Product Description

Burn Off Ovens are used frequently in the coatings, fibers, electric motors and plastics industry. Burn off ovens are designed for removing paint, powder coating, epoxies, lacquers, urethanes and other organic or inorganic compounds from a variety of parts, such as: racks, hooks, jigs, fixture. And also for cleaning polymers from a variety of metal parts, such as: moulds, extrusion dies, screws, nozzles, extruders, hot runners, breaker plates.

► Working Principle

First, the Primary Burner heats the pyrolysis chamber to 420°C, thermally decomposes the organic materials or polymers in a low oxygen atmosphere, the organic materials or polymers are driven off as smoke, and are put through the afterburner that burns the resulting emissions in a direct-flame, leaving only odorless and harmless H20 (Vapor) and C0to exit the exhaust stack. During the process, a temperature-sensing probe in the oxidizing chamber monitors the rate of smoke emission from the parts by measuring the stack temperature. When the stack temperature reaches a preset point, the control system turns on a water spray mist to cool the parts, lowering the smoke emission rate before it reaches an ignition state. The water spray also activates if the oven temperature exceeds its set-point temperature by 30°C.

► Applications

  • Paint & Powder Coating stripping (Racks, Jigs, Fixtures, Paint hooks and hangers)
  • Plastics stripping (Moulds, extrusion dies, screws, nozzles, extruders, hot runners, breaker plates)
  • Auto-Parts and Engine Rebuilding
  • Fiber & Chemicals

► Benefits

  • Low labor cost and simple operation (the operator loads a rack of parts to be cleaned into the oven, closes the door and pushes the start button)
  • Cleaning is fully automatic
  • Short cycle time (about 2 to 4 hours)
  • Optional fuel (Natural gas/Propane gas/Diesel) for burners
  • Safety and no pollution

► Features

  • Primary Burner – The Primary Burner heats the pyrolysis chamber to 420°C, organic materials are driven off as smoke. The burner flame is confined to the combustion chamber never touching the parts.
  • Water Spray System – The water Spray System controls the rate of smoke emissions preventing damage due to ignition or over-heating in the furnace.
  • Afterburner – The afterburner burn the smoke at temperatures ranging from 650°C to 900°C, leaving only odorless and harmless water vapor and carbon dioxide to exit the exhaust stack.
  • Explosion Relief Door – The explosion relief door in the roof of the oven allow excess pressure relief by automatically open and then closing immediately by gravity.
  • Built-In Cart – A heavy-duty structural steel cart is included with burn-off oven. The cart rolls outside the furnace on removable tracks, for ease of loading and unloading.
  • Safety & Controls – Burn Off Ovens include controls the rate of smoke emissions preventing damage due to ignition or over-heated in the furnace. and a dual-element temperature-sensing probe, water pressure safety interlock switch, Y-strainer, automatic solenoid valve, high/low gas pressure switch, and manual bypass with push-to-test circuit area.
  • Control Panel – Burn Off Ovens come standard with a control panel with PLC, HMI, circuit breaker, control relays, interlocks, and terminal strips. The control panel is factory pre-wired prior to shipment.
