Regenerative Thermal Oxidizer (RTO) is a device for treating organic waste gases (VOCs), which oxidize organic matter into harmless carbon dioxide and water through high-temperature combustion. During this process, a large amount of high-temperature flue gas is generated, and if the thermal energy of these flue gases is not recycled, it will cause great energy waste. Stainless steel plate heat exchangers are key equipment for improving the overall efficiency of RTO systems for waste heat recovery.
Stainless steel plate heat exchangers utilize the heat energy of high-temperature exhaust gas to transfer heat to cold fluids (usually fresh air or process water) through heat transfer plates. High temperature exhaust gas is discharged from RTO and enters one side of the plate heat exchanger. When the exhaust gas flows through the heat exchanger, heat is transferred to the cold fluid on the other side through a stainless steel heat transfer plate. The cold fluid is heated in the heat exchanger and absorbs the heat from the exhaust gas. After being cooled, the exhaust gas is discharged, and the heat energy is recovered for preheating fresh air or other process flows.
Heat transfer plates are usually designed as corrugated or other complex structures to increase heat transfer area and efficiency. The material used is 304 or 316 stainless steel, which has excellent corrosion resistance and high strength,
The utilization of stainless steel plate heat exchangers greatly reduces energy consumption and greenhouse gas emissions. Plate heat exchangers have a compact structure, which is smaller in footprint and easier to install compared to traditional shell and tube heat exchangers.
Stainless steel plate heat exchangers are widely used in industries such as petrochemicals, coatings, pharmaceuticals, and food processing
The stainless steel plate heat exchanger plays a crucial role in the waste heat recovery system of RTO organic waste gas combustion furnace, which can effectively improve the energy utilization efficiency of the system, reduce operating costs, and meet environmental requirements. Choosing the appropriate heat exchanger structure and material based on the specific application environment and requirements can maximize its advantages and ensure the long-term stable operation of the system.
