In the 21st century manufacturing world, process heating systems have become an essential part of the overall manufacturing operation for many industries. Almost every finished consumer product requires some form of heat-treating method, whether it is baking, curing, annealing or drying at some point in the production process. Hence, an array of industrial ovens and furnaces exist to specifically suit each production process.
Although process heating equipment is ubiquitous in the manufacturing landscape, an inherent downside exists to deploying it: the creation and emission of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs). With increasingly stringent regulations around VOCs and HAPs, manufacturers must turn to air pollution control systems to stay compliant. Thermal oxidation is the most commonly used method to control these air pollution emissions. Thermal oxidizers — often referred to as incinerator or combustor-type systems — rely on the process of combustion to oxidize VOCs, carbon monoxide (CO) and volatile HAP emissions down into carbon dioxide (CO2) and water (H2O). They can have high destruction-rate efficiencies (DRE) — levels up to 99.99 percent.
