<p>Flue gases from combustion plants have water vapour from the combustion in the flue gas. With a condenser part of the vapour can be condensed and the condens heat be used to heat the return water from a heating system. By humidifying the combustion air with rest heat from the flue gas it is possible by using known technology to cool the flue gas to a temperature in the magnitude of 15 °C under the return water temperature and recover still more heat energy. The water content of the flue gas is high even after the condensation, especially if the return water temperature is high. It is an advantage if the flue gas temperature can be still more cooled, because forceful condensation improves the cleaning of the gas from dust particles and to avoid a vapour plume. This innovation reaches these goals by cooling the flue gas with ambient air.</p> |
