AB The use of flue gas waste heat has been one of the most discussed topics in the field of energy management for a long time now. This is not only an economic question of wasteful use of the obtained heat, but also the ecological consequences caused by the increased amount of emissions, since most of the heat energy mankind still obtains is by burning fossil fuels. There are studies that try to prove that excessive burning of carbon can disrupt the balance of the planet's system, and according to some studies, it is the emissions of carbon dioxide produced by industry that cause the greenhouse effect, and the resulting increase in the temperature of the Earth's surface. Despite the fact that definitive proof of human influence on climate change has not been presented, thermal technology is a source of environmental pollution and efforts to mitigate the consequences of its action definitely have a place in planning the energy economy.
