ABSTRACT A PROCESS FOR INCREASING THE EFFICIENCY OF OR FOR CLEANING HEAT EXCHANGERS FOR THE EXHAUST GASES FROM INTERNAL COMBUSTION ENGINES USED IN STATIONARY INSTALLATIONS This invention relates to a process for increasing the efficiency of or for cleaning the heat exchangers for the exhaust gases from internal combustion engines used in stationary installations to drive heat pumps or for the coupled generation of electricity and heat, as well as a device for carrying out the process. Heat exchangers for the exhaust gases from internal combustion engines used in stationary installations, in particular from diesel engines, that are driven with a mixture of heating oil and reclaimed oil cause deposits in the heat exchangers, particularly of soot, so that their efficiency is reduced. This also means that the overall degree of efficiency of such an installation is reduced or that the mechanical efficiency of the internal combustion engine falls as a result of back pressure. The process according to the present invention used to increase the degree of effectiveness of or for cleaning heat exchangers is characterized in that the heat exchangers are from time to time heated by the exhaust gases to a temperature that is sufficient for the automatic cleaning of the heat exchanger surfaces, after removal of a liquid secondary thermal transfer medium or when the circulation of a gaseous secondary thermal transfer medium is shut off.
