Water cycle in thermal power plants

  1. 1. WATER CYCLE IN THERMAL POWER PLANTS
  2. 2. VARIOUS WATER QUALITIES INSIDE THERMAL POWER PLANT • COOLING WATER (BCW,ACW) • BOILER WATER • CONSUMPTIVE WATER
  3. 3. WATER TREATMENT • PRE-TREATMENT OF RAW WATER • FILTER WATER FOR SOFTENING AND DM PLNAT • DM WATER FOR BOILER
  4. 4. WHY AND HOW • The purpose of a water treatment program is to provide heat-exchange surfaces that are sufficiently intact and free of deposits so that design specifications are met. At KSTPS suspended and soluble water impurities are removed with the help of PAC (Poly Aluminium Chloride) while treatment of organic impurities at raw water & circulating cooling water is being carried out with the help of Liquid Chlorine.
  5. 5. WATER FLOW DIAGRAM RAW WATER DRINKING WATER CLARIFLO CULATOR U/G STORAGE TANK SOFTENING PLANT BCW MAKE UP GRAVITY FILTER DM PLNAT BOILER MAKE UP
  6. 6. DM PLANT For removal of Total Dissolved solids such as Ca, Mg, Na,Cl,So4, Alkalinity, Silica etc. ACF UCFT STRONG ACID CATION DM STORAGE WATER TANK DEGASSER MIXED BED WEAK BASE ANION STRONG BASE ANION
  7. 7. COOLING WATER • • • • TO AVOID SCALE FORMATION TO CONTROL CORROSION TO CONTROL MICRO BIOLOGICAL GROWTH TO CONTROL VACUUM IN CONDENSER
  8. 8. VARIOUS COOLING WATER SYSTEMS • ONCE THROUGH COOLING WATER SYSTEM • OPEN RECIRCULATION COOLING SYSTEM • CLOSED CYCLE COOLING WATER SYSTEM
  9. 9. pH • pH is a measure of how acidic/basic water is. • The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. • pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. • pH is reported in "logarithmic units. Each number represents a 10-fold change in the acidity/basicity of the water. Water with a pH of five is ten times more acidic than water having a pH of six.
  10. 10. Importance of pH • The pH of water determines the solubility (amount that can be dissolved in the water) and biological availability (amount that can be utilized by aquatic life) of chemical constituents such as nutrients (phosphorus, nitrogen, and carbon) and heavy metals (lead, copper, cadmium, etc.).
