Captive Power Plant #1

Captive Power Plant#1 was established in 1959 inside the premises of Rourkela Steel Plant with a main objective to generate captive power to meet the emergency requirements of Rourkela Steel Plant as well as supply of air to Blast Furnaces.  Medium Pressure Boilers were added during 1978 to meet the factory steam requirements of RSP.  Boiler coal is used along with BFc gas & Mixed gas for running the Turbo Alternators and Turbo Blowers in CPP#1.

During the  recently concluded Expansion Project, Power Blowing Station was added for gainful utilisation of BFc gas generated from Blast Furnace No.5.  As an environment friendly measure,  Top Recovery Turbo Generator was installed for generating power through  gainful utilization of high pressure generated from top of the Blast Furnace. Green Power is  being generated  through  Back Pressure Turbo Generator  by gainful utilistion of latent heat generated from dry quenching operations of Coke Oven Battery No. 6.

Good quality boiler coal is sparingly used in Captive Power Plant#1. The dry fly ash generated from the boilers is being given to Fly ash users free of cost. The availability of dry Fly ash from CPP#1 is given below;
