Dear friend from Bangladesh,
When considering the basic flow diagram of a thermal power plant following flows of feedwater system can be considered a) turbine condensate b)heat distribution system heaters c) regenerative systems condensate d) chemically treated water from water treatment plant. Turbine condensates which is recycled back is also chemically treated rather termed as water conditioning to suit boiler, turbine,heaters, and other equipments metallurgical and variable process requirements to protect against scaling & corrosion,

Turbine Condensate
Dear friend Shrutt
1.Let a natural circulation boiler having Steam Pressure of 40 Kg/Cm2, hardness of turbine condensate must not be over 10 microgram-equivalent/kg.
2. When steam pressure is in between 40 Kg/Cm2 to 100 kg/cm2 hardness of turbine condensate should be restricted to 5 microgram-equivalent/Kg
3. When it is greater than above two cases hardness must not exceed 1 microgram-equivqalent/Kg
4. for once through system it is restricted to 0.5 microgram-equivalent/Kg
