Verfahren und Anordnung zur Energienutzung von Rauchgasen in kohlegefeuerten Kraftwerken

摘要

The invention relates to a process and device for making use of the energy from gases in coal-fired power stations in which the flue gases are cleaned in a flue gas washer (1) and taken to a cooling tower. The basis of the invention is to make use of the energy content of flue gases of coal-fired power stations at and below the acid condensation point. This is achieved by the invention in that the flue gases in the intake region of the flue gas washer are cooled by the acid-proof heat exchanger (8) to below the acid condensation point, dripping acids are taken from the flue gas washer sump and neutralised and the cooled flue gases are directly taken into the washing region and taken off to the cooling tower without reheating.
