Nov 17, 2017 · Minor water requirements in thermal power plants are for, for example, boiler feed water makeup (typical use: 0.02–0.03 m 3 /MWh e). Water use can be described through (1) its withdrawal from the source and (2) its consumption, which is the amount not returned to the source. In the latter case, most of this water is transferred to the
