The steam generator unit has to produce steam at highest purity, and at high pressure and temperature required for the turbine. This is made up of Economizer, the steam drum with all internal and external fittings and chemical dosing arrangement, generating tubes (with necessary headers for uniform distribution of water flow) forming the [[Furnace]] chamber and superheater coils. Necessary safety valves are located at suitable points to avoid excessive boiler pressure.
