Chemistry in Thermal Power Stations of an utility involve purification of raw water for different requirements and maintenance of particular quality of water in different equipment and stages of the process. This is done by the use of chemicals and suitable equipment.

Raw water(main water input)[]

Raw water has to be obtained for general use (excludes steam turbine condenser cooling water which involves large quantities of water-processing dealt separately)including the power station process requirements. Depending on the quality of this water and the the multiplicity of uses it has to be put into, it may require pre-treatment such as flocculation and subsequent treatment.
