Thermal oxidizers process air pollution from industrial plants by decomposing pollutants at a high temperature and releasing the less-harmful gas into the environment. Let TANN find an environmental system that meets your needs and helps you become more environmentally friendly.
Every thermal oxidizer that TANN manufactures is available with the option of secondary heat recovery systems incorporated for additional energy recovery. All of our equipment is backed by the best warranties in the industry and includes around-the-clock service, every day of the year.
Regenerative thermal oxidizers (RTO’s) are the most common oxidizer in today’s market. RTO’s are capable of extremely high thermal efficiencies up to 97%. When considering a replacement oxidizer, RTO’s can cut the customer’s gas cost considerably making the switch an easy decision. Due to their high thermal efficiency, RTO’s can often go into “self-sustain” mode, in which the burner shuts off completely, using zero gas. Longevity is also another big advantage for the RTO, because the heat exchanger and combustion zone are internally lined with refractory insulation… Read More
Recuperative oxidizers use a stainless heat exchanger to preheat the incoming process air prior to entering the combustion chamber operating set point. The heat exchanger will preheat the process air to approximately 400°F within the oxidizers combustion chamber temperature. The burner will provide the remaining energy to heat the process air to the combustion chamber temperature of ~1,400°F. In the combustion chamber, the VOC’s within the process exhaust will convert to CO2 and H2O. This 1,400°F air, now clean, will pass through the opposite side of the heat exchanger, thus providing the energy for the incoming process air… Read More
Catalytic oxidizers use a catalyst to reduce the oxidation temperature. Unlike the 1,400F operating temperature of a thermal oxidizer, a catalytic oxidizer can operate at much lower temperatures such as 600-700F. This lower operating temperature can reduce the operating costs and prove to be the most efficiency solution. Catalytic oxidizers can be either direct (no heat exchanger), recuperative or regenerative. The recuperative style will include either a plate or shell and tube heat exchanger to preheat the incoming air prior to reaching the burner… Read More
Direct oxidizers use a burner to preheat the incoming process air prior to entering the combustion chamber. The burner will provide enough energy to heat the process air to the combustion chamber temperature of ~1,400°F. In the combustion chamber, the VOC’s within the process exhaust will convert to CO2 and H2O. This 1,400°F air, now clean, will exhaust to the atmosphere. Direct thermal oxidizers can be designed in a vertical position or horizontal. Raw gas burners are common to reduce the overall energy consumption. Direct thermal oxidizer can be a low-cost solution for many applications… Read More
