Facts about flue gas exchanger
by Morten Bech Danish Digital Marketing professionelUsing an exodraft flue gas exchanger, the excess heat in your flue gases can be recycled, converted to hot water and used further in your company. The possibilities include reintegrating the waste heat into the original process or other internal use through integration with other processes, space heating, cleaning or bathing facilities. In case you end up recovering more heat than you actually need internally in your business, you can make money by transferring your surplus heat to a second party, such as a municipal district heating plant.
Flue gas as an energy source
Most companies in the manufacturing industry have processes that lead to exhaust gas emissions. What few people realize is that hot flue gases are filled with usable energy. However, this energy usually ends up smoking through the chimney and "out to the birds" instead of benefiting the company. This tedious trend we at exodraft systems would like to change, so with our flue gas exchanger we offer companies to extract the excess energy from their flue gas and use it - in the form of hot water - for various useful purposes.
How does a flue gas exchanger work?
A flue gas exchanger is a heat exchanger designed to extract the energy in hot flue gases and convert it - typically - to hot water. By adding cold water to the exchanger and then heating the exchanger with a flow of hot flue gases, the water in the exchanger absorbs the heat from the flue gases. The result is that the cold water exits on the other side of the exchanger as hot water and - conversely - cools the flue gases in their passage through the exchanger, delivering a quantity of their heat to the water. We have made the following animation, which illustrates the function of the flue gas exchanger in an exodraft Safe Plate heat recovery unit in the context of an industrial plant:
From process to district heating
If you do not need the excess heat that your heat exchanger generates, you can sell the heat to the district heating plant at a price that is advantageous for both parties. You get an extra income from selling heat to the district heating producer and the district heating plant gets the excess heat delivered at a cheaper price, compared to what it would cost to produce the heat itself, using gas, oil and straw. In addition, many district heating plants are very interested in the sustainable and environmentally friendly profile that comes with the recycling of surplus heat, a profile that of course also accrues to you as a provider.
Exodraft heat exchanger in Denmark, Sweden and Germany?
Waste heat recovery (called "wärmerückgewinnung" in German, "varmegenvinding" in Danish - and "värmeåtervinning" in Swedish) can be provided in many different countries. Check our websites for more info.
