1 India Electricity – 2006 Session – II Renovation & Modernisation Presented by: M.R. Ganesan / GM / SSBG Bharat Heavy Electricals Ltd.

2 Boiler & auxiliaries Pressure Part components are designed for hrs of operation (ASME stress values are for hrs.) Selection of various equipments / materials is based on specific input parameters, steam requirements, coal, ambient condition. Original design

3 Pollution Control Equipments Based on output parameters of boilers. Coal / Ash characteristics of coal. Pollution control norms Original design

4 Turbine, Generator & Auxiliaries Designed for ambient & cooling water temperature & blade profile. Components are selected based on operating conditions. Original design

5 Balance of Plant Selection based on specific requirements of inputs of main plant – boiler, pulverizers, TG Electrical, etc. Water quality & quantity. Coal quality & quantity. Original design

6 Boiler components suffer due to Service related damages like Oxidation, Corrosion, Erosion and Creep Fatigue Deterioration in coal quality Unit capacity derating Inadequate spares / quality spares Postponement of overhauls / no overhauls Absence of good O&M practices Aging of old equipments – erosion, material damages Low Availability / Reliability State of art features available now for the Design and Operation Philosophy of yesteryears Need for R&M

7 Benefits of R & M Extended life. Restore lost capacity and /or enhance rated capacity. Improved availability & reliability. Improved heat rate & cycle efficiency. Reduction in auxiliary power consumption. State of art systems for better O & M practices. Low capital requirements compared to green field projects. Low gestation period. Meeting statutory pollution norms.

8 Strengths of BHEL Improvement on design philosophies to suit Indian conditions based on vast experience. Developed technologies / retrofits to improve the performance e.g: Smart Wall Blower System. Gravimetric feeders with micro processor controls Steam Tube Leakage Detection (STLD) system By-pass Over Fire Air System – NOx Control High efficiency BFP cartridge.

9 Korba East Thermal Power Station - CSEB (2x120 MW) R&M executed by BHEL Scope of work based on RLA and Condition Assessment. Units running consistently at PLF > 80%. Kothagudem Thermal Power Station – APGENCO (Station B&C – 4x110MW uprating to 4x120 MW) Scope of work arrived at after RLA studies and Condition Assessment and specified by APGENCO. Uprating to 120 MW implemented. Units running consisting at PLF > 85%.

10 GSECL – Ukai TPS (2x120 MW) Scope: Turnkey execution of R&M works of 2x120 MW Ukai TPS Units 1&2 (involving Boiler & Aux, TG & Aux, C&I, Balance of Plant and Electrical). HPGCL – Panipat TPS (1x110 MW) Scope: Uparting of 1x110 MW SKODA Turbines (involving Boiler & Aux, TG & Aux, C&I, Balance of Plant and Electrical) R&M under execution by BHEL

11 Adjustment required for compilation of final R&M cost: Suggestions Environmental requirements, like ESP addition, etc. Exclude normal O&M spares Additional allocation for extent of BOP scope The scope & price should be based on the recent RLA study. Performance guarantees should be in line with MOP guidelines.
