摘要： A steam power generating system includes at least one steam generator, at least one turbine assembly, at least one electric generator, at least one condenser and a feedwater preheat arrangement including at least one injection feedwater heater connected to the condenser and the turbine assembly. The injection feedwater heater includes a main heater body and at least one injection nozzle. A predetermined amount of condensate water from the condenser is arranged to be pumped into the main heater body. The condensate water passing through the water inlet is arranged to be injected into a heat exchange compartment through the injection nozzle for creating a negative pressure in the heat exchange compartment. The negative pressure draws a predetermined amount of steam from the turbine assembly to enter the heat exchange compartment for mixing with the condensate water.

摘要： An injection feedwater heater for a steam power generating system includes at least one main heater body and at least one injection nozzle. The main heater body has at least one heat exchange compartment, at least one water inlet, at least one steam inlet, and at least one water outlet formed on the main heater body. The injection nozzle is provided in the main heater body at a position adjacent to the water inlet, wherein a predetermined amount of condensate water is arranged to be pumped into the main heater body through the water inlet. The condensate water passing through the water inlet is arranged to be injected into the heat exchange compartment through the injection nozzle for creating a negative pressure in the heat exchange compartment. The negative pressure drawing a predetermined amount of steam to enter the heat exchange compartment for mixing with the condensate water.
