Rourkela, March 14
The Captive Power Plant -3 (CPP-3) of SAIL, Rourkela Steel Plant (RSP) has set two fresh records in average single-day power generation on consecutive days.
CPP-3 had created a new record by producing 48.56 Mega Watts (MW) of Electrical Power on 12th March, 2022. It took less than 24-hours for the record to be broken yet again. Blazing a trail of success, on the very next day that is on 13th March, 2022, the Unit broke this record to create another new one by generating 49.02 MW of power on a single-day. Notably, the previous best of the unit was 48.11 MW achieved on 3rd February, 2021.
It is worth mentioning here that the Captive Power Plant -3 consists of Steam Turbine Generators in Power Blowing Station, Top Recovery Turbine Generator and Back Pressure Turbine Generator.
Expressing happiness over the back to back records, Atanu Bhowmick, Director In-Charge, RSP has congratulated the Collective and urged them to make excellence a habit. “Let’s continue to excel in every endeavour of ours,” he added.
It is worth mentioning here that dedicated team of CPP-1 led by B Sunil Kartha, CGM (Power) and S L Das , GM and in-charge (CPP#3) has been making unrelenting efforts to enhance the performance of the Unit. The Unit registered best monthly performances in this financial year 2021-22 including the best February since the inception of CPP#3.
These outstanding achievements were possible through first time major overhauling of all three Turbo-blowers of Power and Blowing station leading to savings of 12 Tonne steam per hour per turbo-blower which was efficiently utilized for enhanced power generation in Steam Turbine generators. Besides, replacement of 20MVA TRTG Generator Transformer with 25MVA transformer, rectification and precision adjustment of control valve spindle of Steam Turbine Generator#2, re-commissioning of sulphuric acid dosing system at cooling towers of PBS for control of clarified cooling water chemistry of turbo-blowers and steam turbine generators resulting in enhanced efficiency and reduced maintenance requirements helped in achieving the enhanced performance. A series of incremental system improvements like arresting steam leakages; optimizing the boiler loadings and thereby their efficiencies ; enhancing the vacuum in condensers in STGs and in turbo-blowers; enhancing the reliability of major power plant equipment and related auxiliaries; rationalization, optimization and balancing of steam generation in boilers and their effective utilization in turbine generators and turbo-blowers were some of the other major initiatives undertaken by the unit.
This is a great achievement considering the fact that this record power generation was done in addition to the continuous supply of the required cold blast volume of 3,30,000 Nm3 of air with pressure of 4.10 kg/cm2 to Blast Furnace#5 for hot metal production and by enhancing the reliability of CDCP boilers for facilitating production process in COB#6.
This feat by CPP#3 was facilitated by the support and efforts of EMD, Blast Furnaces Department, CDCP, Instrumentation Department, Centralised Electrical Departments etc.
