State owned Indian power company NTPC has commissioned the country’s first ultra-super-critical unit at Khargone in the state of Madhya Pradesh.
With a capacity of 660MW, the new power unit will have an efficiency of 41.5%, which is 3.3% more than the traditional super-critical units.
With steam parameters of 600 degrees centigrade and 270 kg/cm2 pressure, the new unit has been designed to consume less coal and produce the equivalent of power in comparison to super-critical plants.
NTPC said that the Khargone plant will feature two ultra-super-critical units with 660MW capacity each, thereby bringing the total plant capacity to 1,320MW.
Additionally, the company said that the new plant will have the capacity to reduce carbon emissions by 3.3%.
The required facilities for the sustainable running of the plant, such as fuel handling and transportation systems, are also in place. The company said that the plant is expected to start commercial operations soon.
Through coal, gas, hydro, solar and wind plants, NTPC is meeting about 23% of the power demand in the country.
In April 2019, GE Power installed its first turnkey full flow wet flue gas desulphurisation (WFGD) unit at NTPC’s 500MW super thermal power project site in Vindhyachal, Madhya Pradesh.
For the project, GE Power delivered a WFGD system for the 500MW pulverised coal-fired boiler unit on a full turnkey basis that included designing, engineering, manufacturing, testing, civil works, erection and commissioning.
The installation of FGD will be the first limestone-based WFGD that has been commissioned in an NTPC power plant suitable for continuous operation at the 500MW unit for 100% gas flow.
