Abstract :

India has progressed a lot by increasing its electricity generating capacity from 1362MW at the time of independence to 209276.03 MW as on 31st October 2012,which compromises of 19.03% hydro, 66.54% thermal, 2.31% nuclear and 12.10% renewable energy sources. Contribution of referred thermal is more than 56.80% from coal based steam turbine units. In addition to the installation of new thermal unit, renovation, modernization and refurbishment of the coal based old thermal units remained on the national priorities for more than last two decades. Coal quality deterioration is leading a new challenge before the design engineers to suitably innovate the coal based thermal power plants for degraded coal. CFBC are attracting the attention of power producers as an alternative to the conventional PCC boilers. This paper is focused on energy and exergy analysis of CFBC boiler and its comparison with PCC boiler under the compulsion to produce steam even when coal quality is very poor.
