What is cooling water system in a thermal power plant?

In a thermal power plant, Cooling Water system is one of the most important power plant systems which ensure continuous supply of cooling water for steam condensation in condenser and other plant equipment. Power plants are key elements of national infrastructure and eco-friendly solutions are required for commitment to the society.

How to optimize water consumption in thermal power plants?

Out of total water consumption value of 3.2, 2.2 m 3 /MWH is being consumed by circulating cooling water system and 0.6 m 3 /MWH is being consumed by an ash handling plant. The following strategies can be used to optimize water consumption in thermal power plants: Minimize the withdrawal of freshwater and promoting recycling and reuse.

What is the main source of water for Indian thermal power plants?

The main source of water for Indian thermal power plants is sea water or surface water sources being rivers, canals and ponds. In some cases, groundwater sources are also used for meeting the freshwater requirement of thermal power plants. The cooling water systems generally are of two types: direct cooling system and an indirect cooling system.

Which cooling technology is best for thermal power plants?

For thermal power plants,closed-cycle recirculating wet cooling with evaporative cooling towers is a recommended technology, although it does not completely eliminate water withdrawals due to evaporative water losses to the atmosphere.

Can thermal power plants reduce water consumption?

Based on the notification issued by MoEF, all the existing thermal power plants are expected to reduce specific water consumption up to 3.5 m 3 /MWH (Mishra et al. in Paper on water resource management for 2 × 660 MW coal-based power plant and comparatives for wet and dry cooling system, New Delhi, India, 2016).

Why is water important in thermal power plant?

Water is one of the most important resource requirements in thermal power plant for process cooling in the condenser, ash disposal, cooling of plant auxiliaries and various other plant consumptive uses.
