PRODUCT GROUP OVERVIEW

Stelter & Brinck, Ltd. designs and manufactures thermal and catalytic fume oxidizers. We have an oxidizer to fit your VOC abatement needs.

TFO: Thermal Fume Oxidizer
VOC emissions entrained in an air stream are drawn into the oxidizer's process air fan. The fan then discharges the resultant airflow into the oxidizer's heat exchanger. The airflow is preheated through the tube side of the heat exchanger and then enters the combustion section. The VOC and air mixture is uniformly exposed to the conversion temperature for the required residence time. The conversion of the VOCs to carbon dioxide and water in their vapor phases occurs under these conditions via an exothermic reaction. The heated airflow is now clean and passes through the shell side of the heat exchanger where heat is transferred from the clean stream to the contaminated inlet stream. The heat exchanger helps to keep fuel consumption at a minimum. The clean air, after passing through the heat exchanger's shell side, enters the exhaust plenum to the atmosphere.

Afterburner
Stelter & Brinck, Ltd. afterburners are ideal for high opacity airstreams containing smoke and strong odors. Lower airflows and high temp airflows are candidates for VOC removal with an afterburner. The afterburner is a direct thermal oxidizer and provides for the lowest capital investment.

CFO: Catalytic Fume Oxidizer
If your VOC laden airstream is free of potential catalyst fouling agents or poisons, our catalytic units are your number one option for VOC abatement equipment. Our catalytic fume oxidizers use a noble metal catalyst monolith to destroy the VOC fumes. Because the catalytic unit uses a lower temperature airstream for effective VOC destruction, the unit uses less fuel and lowers the associate operating costs. Our catalytic units are standard with heat recovery to preheat the incoming VOC air stream to further reduce energy costs. Secondary heat recovery is available to provide hot air for use elsewhere in the process or facility.
