Key Technical Features :
- Supercritical Boilers with vertical water walls and internal rifle tubes simpler in construction having lower pressure drop. Furnace designed for lower slag deposition and lower NOx fuel firing system
- STG of capacity 660 MW each consists of one combined HP/IP and two (2) LP cylinders, tandem –compound quadruple exhaust, condensing reheat turbine designed for high operating efficiency and maximum reliability
- STG auxiliaries like Boiler Feed Pumps (BFP), Condensate Extraction Pump (CEP), DM cooling water pumps, Vacuum pumps, heat-exchangers etc.
- Deaerator with stork design, HP/LP Heaters
- L&T make dual pressure once through type Condensers having divided water box
- Concrete volute type cooling water pumps
- HVAC system, fire fighting system, fuel oil system etc.
Fuel : Indian Coal
Year of commissioning : 2016
