The principle of smoke whitening: application of air to air plate heat exchangers

Smoke whitening is a process that involves the use of air to air plate heat exchangers to reduce the amount of smoke emitted from industrial processes. The principle behind this process is based on the fact that the smoke generated during industrial processes contains a lot of heat energy that can be recovered and reused.

The air to air plate heat exchanger works by transferring heat from the hot smoke to the incoming air. The heat exchanger consists of a series of plates that are arranged in a way that allows the hot smoke to flow through one set of plates while the incoming air flows through another set of plates. As the hot smoke flows through the plates, it transfers its heat to the plates, which in turn transfer the heat to the incoming air. This process results in a reduction in the temperature of the smoke and an increase in the temperature of the incoming air.

The air to air plate heat exchanger is an effective way to reduce smoke emissions from industrial processes. By recovering the heat energy from the smoke, the process can help to reduce the amount of fuel needed to generate heat, which in turn reduces the amount of smoke generated. This process is also environmentally friendly, as it reduces the amount of pollutants released into the atmosphere.

Overall, the principle of smoke whitening through the use of air to air plate heat exchangers is an effective way to reduce smoke emissions from industrial processes while also recovering valuable heat energy.
