NOTE
1) The purpose of Water Balance Diagram is to show the expected water consumption of Vinh Tan 4 Extension Power Plant Project. Therefore intermittent cases are considered based on average water consumption.
2) The flowrate in each table is based on average water consumption & discharge flow, and washing water for GAH, ESP, Chimney, etc. which will be required during plant overhaul (Not required during Plant normal operation) is not Considered.
and maximum water consumption of each consumer in the intermittent case will be considered in each system or equipment design, so not shown in this WBD.
3) 1% cycle makeup at BMCR is considered only to calculate Demi. water plant capacity as per Contractual requirement, but it is NOT considered in total freshwater consumption because of following reasons ;
- In case of super critical boiler for VT4 Extension Project no boiler blowdown water is generated during normal operation.
- All water or steam losses from power generation cycle such as boiler / gas air heater / gas gas heater soot blowing steam, and sampling water are already included in total Demi. water consumption.
4) Quenching water for boiler blowdown is not included in total water consumption because normally blowdown is not required during normal operation for once through type boiler and 1% makeup is already considered.
5) Potable water consumption is calculated from 250 working people in Vinh Tan 4 Extension Plant, 130 liter/day/person, and design capacity of potable water treatment is 40 m3/day.
6) Required Raw water for Vinh Tan 4 Extension Project will be supplied from Sea or Lake, therefore Seawater RO system system & Lake water treatment system will be supplied either.
But this Water Balance Diagram is based on the case that seawater is utilized as Raw water.

NOTE
1) The purpose of Water Balance Diagram is to show the expected water consumption of Vinh Tan 4 Extension Power Plant Project. Therefore intermittent cases are considered based on average water consumption.
2) The flowrate in each table is based on average water consumption & discharge flow, and washing water for GAH, ESP, Chimney, etc. which will be required during plant overhaul (Not required during Plant normal operation) is not Considered.
and maximum water consumption of each consumer in the intermittent case will be considered in each system or equipment design, so not shown in this WBD.
3) 1% cycle makeup at BMCR is considered only to calculate Demi. water plant capacity as per Contractual requirement, but it is NOT considered in total freshwater consumption because of following reasons ;
- In case of super critical boiler for VT4 Extension Project no boiler blowdown water is generated during normal operation.
- All water or steam losses from power generation cycle such as boiler / gas air heater / gas gas heater soot blowing steam, and sampling water are already included in total Demi. water consumption.
4) Quenching water for boiler blowdown is not included in total water consumption because normally blowdown is not required during normal operation for once through type boiler and 1% makeup is already considered.
5) Potable water consumption is calculated from 250 working people in Vinh Tan 4 Extension Plant, 130 liter/day/person, and design capacity of potable water treatment is 40 m3/day.
6) Required Raw water for Vinh Tan 4 Extension Project will be supplied from Sea or Lake, therefore Seawater RO system system & Lake water treatment system will be supplied either.
But this Water Balance Diagram is based on the case that Lake water is utilized as Raw water.
