<p>In the process for cleaning of flue gases of a power plant boiler, the flue gases are dust filtered at first and then wet desulfurized. By the wet desulfurization the flue gases are cooled down and have to be reheated before they are fed to the stack of the power plant. In known processes the flue gases to be reheated are reheated by a flame burning oil or gas. This reheating is expensive and leads to the handling and storage of a further fuel in the power plant. In order to avoid this disadvantages, according to the invention the flue gases are reheated by means of reheating energy of at least one reheating flame burning coal dust. Coal dust is a fuel which is available in a power plant, the power burners of which burn coal dust.</p> |
