Safety Relief Valve: The safety diaphragm is a discharging device. After blasting, a new diaphragm shall be placed.
Extraction Unit (with Ejector): Extraction unit includes (first/second stage) air ejector, (middle/rear) cooler, which could be tailor made.
Low-pressure Heater: To collect certain volume of used steam from the steam turbine to heater, and by which the water into the boiler is heated for a higher temperature. This process decreases the steam exhausted into the condenser, and thus lower down the energy loss, which improves the recycle efficiency of the thermal-dynamic system.
