Name of Project : 2x660 MW Chhabra Supercritical Thermal Power Project, Rajasthan, India
Owner : Rajasthan Rajya Vidyut Utpadan Nigam Limited, India (RRVUNL)
Client : Larsen & Toubro Limited, India
Capacity : 2x660 MW (Supercritical)
L&T-S&L’s scope : Complete Basic and Detail engineering for the entire EPC of the project
Configuration :
- Two (2) L&T-MHPS make Boilers
- Two (2) L&T-MHPS make Steam Turbine Generators (STGs)
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
- Metallic casing type cooling water and auxiliary cooling water pumps
- Two (2) L&T Make 185 m high Natural Draft Cooling Tower
- 275 m High twin flue brick chimney
- Complete Balance of Plant viz. HVAC system, firefighting system, fuel oil system, ash handling system, coal handling system, water system, compressed air, mill reject system, Electro-chlorination, tanks, hydrogen generation plant etc.
Fuel : Blended coal (Indian and Imported coal in ratio of 70:30)
Year of commissioning : 2017
