Method for improving the efficiency, respectively to provide for the cleaning of heat exchangers for exhaust gas from internal combustion engines, those exchangers belonging to stationary plants intended to actuate heat pumps or to the paired production of electric current and heat. The technical problem is to achieve a continuous operation with low maintainance cost. The method according to the present invention, designed to improve the efficiency, respectively to provide for the cleaning of heat exchangers, is characterized in that the heat exchanger is heated, temporarily after emptying a secondary heat conveying liquid medium or upon an interruption of the circulation of a secondary heat conveying gas medium, by the hot exhaust gas up to a temperature sufficient for an automatic cleaning of the heat exchanger surfaces. |
