Abstract: A waste heat recovery system is provided where a waste heat source is utilized to vaporize a working fluid which in turn powers a turbine to generate power in a heat engine. A heat exhanger is placed between a waste heat source in an industrial process and an evaporator. The evaporator is connected to a turbine chamber further connected to a multi-chambered condensation unit. Each chamber of the multi-chambered condensation unit has a valved inlet port and a valved outlet port. The valved inlet ports of each chamber of the multi-chambered condensation unit are connected to the turbine chamber outlet. The multi-chamber condensation unit includes a number of condensation chambers, each chamber including a plurality of computer controlled valves. The condesation chambers are sequentially evacuated causing the vapor to be drawn through the turbine and brought into the condensation chambers one at a time. A reservoir is provided which collects the condensate where it is pumped back to the evaporator.
