Cooler KU

The hot gases flow into the cooler vertically downwards along the cooling elements. The gases are deflected through 180° and a pre-separation of the coarse dust takes place.

KU Cooler Heat Exchanger

The danger of the dew point

The cooling air has to be preheated if it is likely that the temperature could fall below the dew point on the cooling elements during the cooling of hot process gases.

Unlike KS, preheating of cooling air is provided with KU. In this case, a partial flow of heated cooling air and fresh air are sucked in together from the cooling air fan.

A pre-selected mixing temperature is regulated prior to entry into the cooling elements by opening or closing the fresh-air valve.

Cooler Cleaning

The cooling elements are designed so, that the cooler cannot become clogged up with dust. An automatic cleaning device is installed for sticky dust.

How the cleaning system works

A pendulum device with cleaning chains is moved by a gear motor from one side of the hood to the other. The cleaning chains scrape adhering dust off the cooling elements.

The parking time depends on the type of dust and the dust content in the polluted process gas. The path of the chain holder is limited by two proximity switches.
