Gas coolers

Each enterprise or production owns boilers that provide heating of buildings, steam generation and water heating for industrial needs. In the process of burning fuel, a large amount of heat along with exhaust gases is released into the atmosphere, and, therefore, has a negative impact on the environment. This issue is even more relevant for high-temperature production, where the temperature indicators of exhaust gases reach very high values. To reduce the temperature of the exhaust gases to the levels of environmental requirements, special gas coolers are required.

Gas coolers are heat transfer units that simultaneously perform the function of heating incoming flows with resulting heat, which can be used for industrial needs. Thus, the principle of heat transfer brings double benefit: the combustion products are cooled and the incoming air is heated.

Design of OPT gas coolers

OPT gas coolers, which belong to the new generation equipment, will most effectively handle the double task. Operating principle is based on cross-motion of gas medium, and special steel panels with a finned surface serve as a heat-transferring element. Gas and air flow travel in perpendicular directions relative to each other through a module that consists of the panels.

Assembly options for modules of OPT gas coolers:

A set of basic panels forms an element of the module:

The finned panel is combined with the same panel (lid). Moverover, the edges on one side alternate with the edges on the other side.
The finned panel is closed with a smooth lid without fins, and a small fin pitch is used.
Panels are interconnected with finned and smooth side. The panels are interconnected by finned (first panel) and smooth side (next panel), while the edges of each panel go across the edges of the previous panel. This is the way the channels are formed for the cross flow of two medium.

In the first and second option, spacers are installed between the panels so that they create the next channel with the transverse direction of the medium flow.

In case of high temperatures with rapid steel heating, thermal stresses may occur. OPT coolers have high thermoplasticity, so stresses do not cause destruction of the unit, resulting in a long operational life.
