【Abstract】 Type N50-8.83 condensing turbines were manufactured in 1960s. This paper discusses the feasibility of converting these turbines into co-generating units without changing much the basic system and their auxiliaries. Through thermal dynamic calculation, construction analysis and schematic comparison, it is believed that this is technically feasible and economically reasonable.更多还原
