Description
The vapour content x is a dimensionless ratio between 0 and 1. It is defined by the ratio of mass of vapour and total mass. The total mass is calculated from the sum of fluid mass and vapour mass. If the vapour content is x=0, the evaporation medium is completely liquid, x=1 means dry saturated vapour, a value in between means wet vapour with a variable liquid content. Separating and throttling calorimeters are used to determine the vapour content. In practice, devices to determine the vapour content are used in steam power plants, downstream of steam turbines or at steam boilers upstream of the super heater.

Training Program:
ET 805.50 uses water as working medium. Water vapour is also known as steam. The ET 805.50 trainer uses a two-stage method to determine the vapour content. A separating calorimeter with cyclone water separator is used to determine vapour contents with a high liquid content (0,5<0,95). the="" liquid="" part="" is="" separated,="" cooled="" and="" collected="" in="" a="" measuring="" cup.
A downstream throttling calorimeter is used to determine vapour contents between x=0,95 and x=1. The wet vapour is depressurised in this process. The remaining vapour part is depressurised and then liquefied in a water-cooled condenser and also collected in a measuring cup. The two quantities can be used to determine vapour mass and total mass to calculate the vapour content.

Technical Specifications:
Sensors measure the pressure and temperature before and after depressurisation. The measuring results can be used to determine the vapour content with the h-s diagram. The water vapour has to be generated externally, e.g. with the electrical steam generator AFT027. ET 805.50 is recommended to determine the vapour content of the steam power plants ET 805, ET 830, ET 850 or ET 833.
