Flue gases from gas turbines, boilers and combustion generators are discharged to the outside and are unused in many industrial plants. But these wasted energy reserves could for the most part be harnessed by heat recovery from flue gas.
By transferring the thermal energy of the flue gas stream, for example, a second, spatially separated medium can be heated or other parts of the production can be heated. This system can also be used to heat other heat sources, such as service water, and in an uncomplicated way.
To ensure that the energy is also available when there is little or no waste heat from flue gases, heat recovery works most effectively in a combined system. With a combination of exhaust flow heat exchangers and heat recovery from waste gas, which temporarily stores its extracted energy in a buffer tank, the full heat output is available at all times.
For example, manufacturing processes can be reliably supported or the room climate can be kept at an even level.
With today’s technology, however, the exact opposite can be achieved. Air coolers transfer the heat gained to a cooling medium. This then operates the air conditioning system and thus ensures pleasant temperatures in the rooms, for example in summer, without any additional primary energy consumption.
Solutions from exodraft can reduce your company’s need for expensive primary energy by up to 16%. Especially in industries with a high energy demand an enormous savings can be made.
An flue gas heat exchanger reduces the temperatures in the flue gas flow. The resulting energy can be reused almost loss-free with a high degree of efficiency. The possibilities are not only limited to the use for heating or the heating of domestic hot water.
Even manufacturing processes that require a high temperature can be supported in this way. In many cases, the thermal energy is high enough to replace existing complex heating systems. In general, one flue gas heat exchanger can be used for all imaginable flue gases. So it doesn’t matter if oil, gas or an open fire is burned.
Depending on the degree of contamination of the existing flue gas, exodraft offers various solutions that can achieve a high degree of efficiency even with coarse contaminants in the material flow.
A sophisticated design with service openings allows easy and effective cleaning. Should a complete standstill of the system be undesirable, there is also a solution for this. A replacement cassette can be installed quickly and easily in just a few steps.
Heat recovery from flue gas is most effective when there is a high temperature difference. State-of-the- art materials in combination with high-tech coatings permit enormous thermal energies.
For example, the flue gases from gas turbines can be converted with a very high degree of efficiency. exodraft offers individual solutions with a long service life.
So no matter where and how you want to use waste heat for energy generation, special solutions from exodraft, tailored to individual requirements, always offer the highest efficiency with minimum maintenance intensity.
Due to the wide variety of materials and designs, a wide variety of heat exchanger designs are available. Examples are finned, plain or finned tube heat exchangers. Classic are air heaters – the most commonly used design. They are used to heat air or other gases for later use, for example for indoor air.
Due to constantly rising energy prices and ever stricter flue gas regulations, energy recovery from modern companies is no longer an option.
A saving of up to 16% in the required primary energy makes your company more resistant to unexpected price fluctuations on the energy market and significantly reduces CO² emissions. By eliminating the need for heaters for the company’s own manufacturing processes, additional costs can be saved directly.
Experience has shown that with an intelligent solution from exodraft, the return on investment, i.e. the point from which the investment pays for itself, is already achieved after 2 years. Due to the low- maintenance heat exchangers, energy savings can also be expected long after this point.
In addition, the technology also saves emissions, as the flue gases can be cleaned to a certain degree. The condensate can usually be discharged unfiltered as waste water. This is good for the environment and saves additional money in energy-intensive production processes.
