Thermal Power Plant Components, Working and Site Selection

Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.

Biomass cofiring: Why India's target for coal power plants is challenging

The plant has a bowl mill and can only use biomass that is torrefied (preheated at 250300 degrees Celsius to remove volatile matter and reduce moisture). There are even fewer suppliers of torrefied pellets in the market. Nabha Thermal Power Plant (LT, Punjab), similarly, has had no takers so far for its tender on the supply of pellets.

Realtime coal classification in thermal power plants

Realtime coal classification in thermal power plants

As mentioned in Section 1, the change of coal in a thermal power plant typically happens over a period of several hours (referred to as coal transition) and there is an irregular time lag between the coal change at the bunker level and that at the mill or boiler level (Tuttle et al., 2020). Therefore, realtime detection of change of coal in an ...
