A Recuperative Thermal Oxidizer integrates a heat exchanger into the design in order to minimize the fuel used for oxidation. By passing the hot exhaust gasses through a non contact air-to-air primary heat exchanger, recovered heat is used to warm the incoming air to the oxidizer. The results provide you with exceptional performance, substantially reduced operating costs, and industry-leading reliability.
The CPI Thermal Recuperative Oxidizer (TRO) process begins with a booster fan designed to draw the volatile organic compound (VOC) laden process exhaust to the QUADRANT System. From there, the VOC-laden process air stream is then directed into the condensate evaporate section where it is preheated to eliminate any vapor droplets before entering the FLOATING TUBE primary heat exchanger. This step protects the leading edge of the heat exchanger from condensate build-up and subsequent preignition. When the stream enters the FLOATING TUBE heat exchanger, it is continuously preheated at close to the ignition temperature before being sent to the pre-heat burner. The exchange of energy in the primary heat exchanger makes up the basis for fuel savings and economical operation.
A pre-heat burner is used to precisely maintain the combustion chamber operating temperature. The burner is designed to promote mixing of the exhaust gases with oxygen when fired through our specialized combustion system. This innovative design provides the highest degree of flame impingement and high-velocity mixing, leading to airflow and temperature uniformity for which QUADRANT Oxidizers are known.
The contaminated air stream next passes through an elongated high velocity combustion chamber. Here a series strategically placed mixing baffles creates turbulence and improves mixing, helping to prevent temperature stratification. From there the air stream rebounds 180^ to assure proper mixing of all the effluent constituents. Even at low flow conditions, this mixing action provides the highest possible temperature uniformity for industry leading destruction ability at the lowest operational cost.
Once mixed the air stream is held in the dwell chamber long enough to ensure complete combustion of the VOC's. From there the clean stream passes over the FLOATING TUBE primary heat exchanger prior to being discharged to the atmosphere or to auxiliary heating systems such as; secondary air to air recovery, air to water recovery, air to oil recovery, or directly back to the process in a closed loop direct recirculation process.
