MODELING SYSTEM OF ONCE THROUGH STEAM GENERATOR FOR STEAM FLOODING ENHANCED OIL RECOVERY

, 2014
Enhanced Oil Recovery (EOR) is an oil recovery method that involves the injection of fluid which does not originally exist in the reservoir. One of the EOR methods is steam flooding EOR that uses water vapor as the working fluid.

Fuel Controller Design in a Once-Through Subcritical Steam Generator System

, 1978
Established techniques have been applied for modeling a once-through subcritical steam generator in an oil-fired 386 MW(e) power generation system. The model was used to design a fuel controller which was implemented in the actual plant.
