HOW DOES IT
WORK?

Group top

The working principle of the Triogen ORC is presented below.

 

I => II
Pre-feed pump
The pre-feed pump is used to pump the working fluid from the storage vessel to the main pump. The liquid enters the main pump at a pressure of approximately 4 bar.
 

II => III
Main pump, in HTG
The main pump brings the pressure of the working fluid, depending on the rotation speed of the turbine, up to a working pressure of approximately 30 bar.
 

III => IV
Recuperator
In the recuperator the working fluid is preheated by the vapour leaving the turbine.

IV => V
Evaporator
In the evaporator the working fluid is further preheated, evaporated and superheated.
 

V => VI
TurbineIn the turbine the working fluid expands which drives the electrical generator and the main pump.
 

VI => VII
RecuperatorIn the recuperator the working fluid is preheated by the vapour leaving the turbine.
 

VII => I
Condenser
In the condenser the working fluid is condensed through water-cooling
