• In thermal power plant, fraction of the power produced is consumed by power generating equipment and their auxiliaries such as fans, motors etc.
• Auxiliary consumption of thermal power plant is between 8 to 10% of total power produced. For instance, for thermal power plant having 10 MW capacity, auxiliary consumption is around 850 to 1000 KW.
• The main consumers of power are Boiler feed pump, induced draft and forced draft fans.
