The exhaust heat exchangers use waste heat generated during different industrial processes in the form of flue gases. To effectively use the heating power the residual heat power, the residual heat of the exhaust has is then added to a second medium – for instance, the heating water. Hence, the existing residual heat can be reduced by using it for recovery.

The efficiency of the facility can be increased by this system, where expensive energy can be saved and CO2 emissions can be significantly reduced. Hence, it is not only cost-effective, but it is also environmentally friendly.

Usually, an exhaust heat exchanger can achieve a similar effect for a fraction of the expenses as an entire replacement of the heating system. It uses the heat that would otherwise be wasted too, for instance, to keep warm or preheat other molds, tools, and spaces for the manufacturing of products.

Applications for Modern Exhaust Heat Exchangers

Within various industries, exhaust gas exchangers are becoming increasingly popular since the rise of energy have gone up. Recovery from waste heat is especially appealing when no energy can be saved as a result of increasing consumption. Besides saving energy costs, the reduction of CO2 emissions also plays an important role. With the reduction of primary energy of up to 16 percent, pollutant emissions are also significantly reduced which is important in industries that use a lot of energy.

These systems can be used whenever waste heat is generated by flue gases. For example, in bakeries, plastic processing plants, and hardening plants. Since modern manufacturing processes, these industries cannot work without high temperatures and the connected waste heat, hence, they use these systems to make their production plants more efficient.

A conversion of this wasted energy of up to 96 percents into reusable heat or electric current increases the economy and effectiveness of the industry. This makes heat exchanger especially appealing since there is a low need for maintenance and it does not require any additional and continuous costs.

How Does a Heat Exchanger Work?

Each heating system produces some waste hear which is usually lost in the form of exhaust gases. Of course, those gases cannot be directly used for heating. In order to use the exhaust, an exhaust heat exchanger can be used to heat other heating mediums. This means that the heat is not lost, but used for generating energy, without additional costs and consumption.

The exchanger is usually installed between the chimney, boiler, or at the top of a building so that industries are not required to dismantle entire systems which can be quite expensive. This can save both money and time. Hence, this technology will not only reduce energy consumption, but the installation process is simple and there is practically no maintenance needed.

Another benefit of these exchangers is that they use water for heat recovery. This means that some pollutant can already be filtered out and hence, reducing the strain on the filter system.

Conclusion

As you can see, these systems can significantly reduce costs and pollution. They are not only got for all industries but are also good for our environment.
