Thermal Oxidizers

Thermal oxidizers reduce air pollution emissions
from a variety of industrial processes.

Using the principle of “thermal oxidation,” a combustion process, the contaminants within the polluted exhaust gas react with oxygen in a temperature controlled environment. The chemical oxidation reaction destroys the contaminants in the polluted exhaust gas before discharging it back into the atmosphere. What is released is an innocuous emission of CO2, water vapor, and heat.

PCC Thermal Oxidizers

PCC thermal oxidizers operate on the principle mentioned above, which is thermally promoting an oxidation reaction between the pollutant compound in the exhaust gas and the available oxygen. We supply two types of the Thermal Oxidizers: direct fired (afterburner) and recuperative thermal oxidizers.

Direct Fired Thermal Oxidizer

The simplest type of thermal oxidizer, it does not include any type of heat recovery system to recover a portion of the waste heat generated by the combustion process.

A direct fired thermal oxidizer system typically includes:

  • Burner
  • Combustion chamber
  • Blower
  • Air/fuel train
  • Instrumentation and controls
  • Exhaust stack

Typically less expensive than other types of thermal oxidizers, direct fired thermal oxidizers will incur higher operating cost (fuel use) for waste streams that are endothermic.

Recuperative Thermal Oxidizer (Afterburner)

This system is a direct fired thermal oxidizer with heat recovery added at the discharge end of the combustion chamber. 

Downstream heat recovery equipment uses the available heat produced within the thermal oxidizer combustion chamber to reduce auxiliary fuel consumption, produce steam, heat a process air stream, or heat a liquid

stream. A recuperative thermal oxidizer system can have a single heat recovery device or multiple heat recovery devices.

In addition to the recuperative thermal oxidizer systems shown above, a recuperative thermal oxidizer can incorporate:

  • Combustion air preheat to conserve fuel
  • Other heat recover equipment such as a hot oil heater, hot water economizer, or asphalt heater

Recuperative thermal oxidizers can treat multiple gaseous and liquid waste streams that are endothermic and/or exothermic.
