Total DM water which is consumed in Power Plant can be divided into two categories:-
Emergency DM water requirement arises for filling up of De aerator or Boiler. the consumption of the same can be calculated by the Flow meters fitted in the outlet of the Pumps which supply DM Water for emergency requirements.However to calculate the consumption of DM water on a regular basis first it is to be understood in which areas the DM Water is used regularly.
a) DM water is used in TG and SG DMCW systems for the primary cooling of the equipment like MILLS, Fans, Pumps etc. Being a closed loop system theoretically no DM water should be wasted, but practically it is not possible due to various leakages happening inside the system. Hence make up water is added regularly, the consumption of which may vary depending on the make up which may be 3 % or more.
b) The same DM water is added inside the condenser to make up for the lost water during the running of the system. the same is measured by the use of the flow meters fitted in the lines.
all together the total consumption of the plant is measured at the DM Plant outlet and also at the individual system.
