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.

As an important part of the national industry, the steel industry has increasingly strict requirements on its environmental protection. The results show that the total amount of NOx emitted by various equipment in the iron and steel plant occupies the second place in the fixed source. Among them, the NOx emission of sintering process accounts for about half of the total NOx emission of iron and steel plants. Therefore, strict control of NOx emission from sintering flue gas can effectively reduce NOx emission from steel plants.

An air preheater (APH) is general term to describe any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil.

Taking the environment air as the cooling medium, finned tube air cooled heat exchanger is the equipment to cool or condense the process fluid with high temperature in the tube. It is called "air cooler" for short, and is also called "air cooling heat exchanger". Air cooler can be also called as fin blower heat exchanger that is often used to replace the cooling medium of water-cooling shell-tube heat exchanger. Air-cooled heat exchanger is the second most extensively adopted heat exchanger in petrochemical industry, shell-tube heat exchangers being the first.

The air-cooled heat exchanger (air cooler for short) is a heat exchange device that uses ambient air as the cooling medium and the fan forces air to cross sweep the finned tube so that the high-temperature process fluid in the tube can be cooled or condensed. The air cooler unit is composed of fin bundle, fan, frame, shutter, maintenance platform, ladder and other auxiliary parts. Using natural air as cooling medium saves precious water resources, reduces the discharge of industrial sewage, and protects the natural environment. Air cooler can be used for cooling or condensation in oil refining, petrochemical tower top steam condensation, cooling of reflux oil and bottom oil, cooling of various reaction products, cooling of circulating gas and condensing of steam turbine exhaust.

Air Cooled Heat Exchanger (ACHE) is a heat rejection equipment where the excess process heat is rejected to the atmosphere. It works on the principle of convection and conduction to dissipate heat from process fluid to air. The process fluid passes through the tubes and air stream is passed over the tubes to carry away the heat; air streams are created by the fans mounted on the unit. By suitably selecting the tube material, `ACHE` can effectively cool or condense process water, chemicals or any other heat transfer fluid。

A tubular heat exchanger, also named shell and tube heat exchanger, takes tube bundles as the heat transfer core. One fluid flows inside the tubes and the other fluid flows outside the tubes but inside a shell, thus forms cross flow to perform heat transfer.

The Food Grade Plate and Shell Heat Exchanger plate and shell heat exchanger is a heat exchanger with a plate tube as a heat transfer element, also known as a sheet heat exchanger. It is mainly composed of two parts, the plate tube bundle and the shell.

As its name implies, the difference between gasket plate heat exchanger and welded plate heat exchanger is that each piece of plate of the later one is connected to another by welding to form a plate bundle.
