Combustion chambers are incorporated into rotary dryers and kilns and serve to house the combustion reaction and direct air flow into the unit. Not all dryers and kilns utilize a combustion chamber; in some cases they are essential, while in others, they are not necessary, but provide additional benefits. 

For more information on when to use a combustion chamber, or whether or not a retrofit is appropriate for a specific situation, see our article, Rotary Dryers: When is a Combustion Chamber Necessary? 

What combustion chambers are available? 

FEECO designs custom combustion chambers in a variety of configurations, with options including:

  • Single or double shell
  • Refractory-lined
  • Angled
  • Various fuel type accomodations

How often do combustion chambers require replacement? 

The life of a combustion chamber can vary significantly depending on the specific operating conditions – typically anywhere from 3-30 years. In some cases, repair to individual sections may also be an option. 

Damage to the refractory is the most common cause of the need to replace a combustion chamber. Signs that the combustion chamber could be compromised include a decrease in product quality, a rise in fuel costs, or other process inefficiency. 

What is the lead time for combustion chambers? 

Lead time for a combustion chamber can range anywhere from 8 to 12 weeks. 

Is there anything else I need to keep in mind when ordering a combustion chamber? 

Since the rotary drum will need to be shut down during the replacement, this may also be a good time to consider conducting an annual inspection or equipment audit on the unit.

If the combustion chamber was supplied by FEECO and is a direct replacement, provide the serial number. If not a FEECO combustion chamber, FEECO will require drawings of the existing unit.
