How the WET-ORC works
Boundary's WET-ORC unit generates power in a modified Organic Rankine Cycle (ORC) process. The process is similar to conventional ORC, except that the WET-ORC system uses two working fluids (in place of a single fluid), enabling use of ultra-low thermal energy sources to create valuable electricity.
A. Thermal energy is brought to the WET-ORC system's heat exchangers through a pressurized hot water, steam, or thermal oil loop.
B. The high temperature fluids enter the evaporator transferring thermal energy to the working fluid which then flows to the inlet of the expander.
C. Recirculated fluid circulates through the booster and enters the expander at same temperature as working fluid.
D. Mechanical work produced by the expander is transferred to the generator which produces valuable electricity.
E. The WET-ORC expander converts the thermal energy from the high temperature and high pressure fluids into mechanical work to drive the generator.
F. The now multi-phase working fluids travel to the condenser where it exchanges its energy with the incoming cool fluid causing it to return to a full liquid phase for recirculation.
G. Cooled liquid enters the condenser and absorbs the thermal energy from the working fluids as they pass through the condenser.
H. The liquid working fluids are pressurized by the recirculation pump and travels at pressure to the evaporator where it absorbs heat energy from the incoming high temperature fluid.
