Industrial Air Preheater

Delayed Coking Units Air Preheater The Delayed Coking Units Air Preheater is composed of main components such as plate bundle, tube box and box body. The equipment uses fully welded structure plate bundle as the heat transfer unit, stainless steel plate as the heat transfer element, between the plates The use of welding and sealing not only ensures high heat transfer performance, but also solves the safety problem of flue gas leakage. 1. Compared with the traditional preheater, this product has good heat transfer performance, high heat exchange efficiency and compact structure; it is suitable for burning clean fuel with low resistance and reduced waste heat recovery system. 2. Fully welded structure, bulge support between the plates to ensure the overall safety performance of the core, stable and reliable operation. 3. Different from ordinary plate heat exchange products, the plate design fully considers fluid resistance requirements and anti-clogging measures, which greatly extends the service life of the equipment and reduces the loss caused by shutdown. The air preheater adopting the delayed coking device can adapt to the changes in the load of the heating furnace and the nature of the fuel, the exhaust gas temperature is easy to adjust and control, can prevent low-temperature corrosion and prolong the service life of the equipment, and has safe operation, high waste heat recovery efficiency, and energy saving effect With good advantages, it can increase the thermal efficiency of the heating furnace by 7.12%, reaching more than 91%.
