Process for cooling diesel engine exhaust gases

摘要: A process and a suitable arrangement for cooling diesel engine exhaust gases in an gas recirculation system is provided. In order to be able avoid contamination of the heat exchanger as well resulting required regenerating latter case hot flow over large temperature range, carried out at least two steps that flows successively through exchangers which are each adapted corresponding range. By adapting specific small ranges, even up 800° C. can cooled desired low by series connection number different exchangers, without causing significant contaminations particles. use known construction becomes particularly reasonable with respect cost.
