Injection Feedwater Heater for Steam Power Generating System

An injection feedwater heater for a steam power generating system comprising at least one steam generator, at least one turbine assembly, at least one electric generator and at least one condenser, said injection feedwater heater comprising:

• a main heater body having at least one heat exchange compartment, at least one water inlet, at least one steam inlet, and at least one water outlet formed on said main heater body;
• and
• at least one injection nozzle provided in said main heater body at a position adjacent to said water inlet, wherein a predetermined amount of condensate water is arranged to be pumped into said main heater body through said water inlet, said condensate water passing through said water inlet being arranged to be injected into said heat exchange compartment through said injection nozzle for creating a negative pressure in said heat exchange compartment, said negative pressure drawing a predetermined amount of steam to enter said heat exchange compartment through said steam inlet for mixing with said condensate water, said condensate water being heated up by said steam which is then condensed into water and arranged to be discharged out of said heat exchange compartment through said water outlet.
