What is Flameless Oxidation?

Flameless Oxidizer Diagram Flameless oxidation is a thermal treatment that premixes waste gas, ambient air, and auxiliary fuel prior to passing the gaseous mixture through a preheated inert ceramic media bed. Through the transfer of heat from the media to the gaseous mixture, the organic compounds in the gas are oxidized to innocuous by-products, i.e., carbon dioxide (CO2) and water vapor (H2) while also releasing heat into the ceramic media bed.
PCC’s Flameless Thermal Oxidizers are designed to operate safely and reliably below the composite LFL while also maintaining a constant system flow and temperature. Waste gas streams experience multiple seconds of residence time at high temperatures leading to measured destruction removal efficiencies that exceed 99.9999%. Premixing all of the gases prior to treatment eliminates localized high temperatures which leads to thermal NOx as low as 1 ppmv.

Why use a Flameless Oxidizer?

In a global economy with a number of potential control technologies to choose from, it is important for companies to understand their options. It is also important to recognize that environmental regulations can only get more stringent in the future. Forward thinking companies with a strong sense of corporate social responsibility want the best available control technology (BACT) at their manufacturing facilities. Flameless Oxidation has proven to be the best control technology for the Pharmaceutical and Specialty Chemical Industries because of each systems reliability and high emission performance. The figures show below compare the performance of common control technologies for gaseous waste streams with PCC’s Flameless Thermal Oxidizer.
