Butibori Power Project is a coal-based thermal power plant located at Butibori near Nagpur in the Indian state of Maharashtra. The power plant is operated by the Reliance Power.
The Engineering, procurement and construction contract is given to
The basis for generation of electricity in this plant is the reheat Rankine cycle.
Working Process
The plant has two 72 m high tangentially fired, water tube boilers. The boilers have a capacity of 1024 m3/hr each, with the output steam being supplied at 167 bar and 540 °C. The boilers are heated by coal. The coal is initially about 300 mm in size. It is crushed to 20 mm and then put into a coal mill, which pulverizes it into extremely fine powder of around 70 microns. The powdered coal is then supplied to the top of the boilers via tubes and primary air (PA) fans, where it is burnt to generate heat and convert the water in the boilers to steam.
The steam generated in the boilers is then supplied to the turbine, which is coupled to a generator. The steam is supplied via 2 out of 3 boiler feed pumps. Two pumps are always active, while one pump is on standby. The turbines run at a constant speed of 3000 rpm, so as to provide a steady output of 50 Hz. The turbines are divided into 3 parts : High Pressure (HP) turbine, Intermediate Pressure (IP) turbine and a Low Pressure (LP) turbine. The steam is supplied to the HP, which sends it back for reheating. This reheated steam then goes to the IP and the LP, which in turn run the generator to produce electricity.
The steam let out from the turbine goes to a
