A calorimeter design for performance evaulation of steam seperators

Dryness fraction (quality) of the steam is highly important in places where steam is generated, consumed and conveyed. Steam separators which allow separation of saturated steam and saturated liquid phases from each other are used in steam boilers, on steam lines and consumption points with different types. In the scope of this study, some tests have been realized on a test unit which was designed and manufactured for performance evaluation of horizontal cyclonic type saperators. This is one of the seperator types used for increasing dryness fraction of steam in the upper (steam) drum of water tube boilers. The test unit consists of 4 pcs main sub-systems. These are; the electric powered steam generator where required steam sample for the tests is generated; steam drum including separator; calorimeter unit used for measurement of dryness fraction of steam and steam superheater designed for verification of measured values by the calorimeter. Dryness fraction values of steam at the inlet and outlet of the separator, required for performance evaluation of the separator have been obtained by separating and throttling calorimeter method which is one of the methods for measurement of the dryness fraction of steam. It is observed from the results that, efficiency of the investigated horizontal cyclonic type separator increases with increased test pressure.
