The fuel is supplied by Rajasthan State Mines & Minerals Limited (RSMML). An additive to fuel is limestone, which is added in pulverised form to the lignite, for the purpose of neutralising the sulphur Oxides (SOx); Sulphur Oxides are formed as a byproduct of combustion of lignite containing sulphur as its constituent. Limestone is also supplied by RSMML. Lignite cost is nearly Rs400 per MT.
Giral Lignite Power is country’s first lignite-based power plant in Rajasthan and is in fact first power plant in the world in operation, at-least partially, using lignite having sulphur content in the range of 6%. But as the technology was not fully proven and matured for smooth and efficient operation, it faced design problems in its main equipment.
Giral Lignite Thermal Power Project is a 2 x 125 MW plant owned by Rajasthan RV Utpadan Nigam (RVUN), the publicly owned power generation company in Rajasthan.
