6 FAQs about [Steam ejector energy storage]
How does a steam ejector work?
This work introduces a steam ejector to couple the TES and the thermal power unit (TPSE) by extracting main steam and reheating steam for thermal storage during low periods. The high and low-pressure inlets of the steam ejector are the main steam and reheat steam after the heat exchange.
Can a steam ejector reduce energy waste?
The steam ejector can minimize energy waste as it only requires a small amount of energy for its activation [ 3, 4, 5 ]. Recently, the steam ejector refrigeration system gained much research attention because of its capability to recycle working fluid to generate a second flow stream.
Why is steam ejector performance important?
The steam ejector is a crucial component in the waste heat recovery system. Its performance determines the amount of recovered heat and system efficiency. However, poor ejector performance has always been the main bottleneck for system applications.
What is the working medium of a steam ejector?
The working medium in the steam ejector for this work is 11.9 MPa main steam, which can be suitably depressurized to achieve safe and stable operation of the TPSE system, depending on the actual steam ejector's piloting capacity. Therefore, it is important to study the inlet pressure of the working medium of the steam ejector.
How many fluids are in a steam ejector?
There are three fluids in the steam ejector, the high-pressure working fluid, which is the main steam after the first heat transfer; the low-pressure induced fluid, which is the reheat steam; and the mixing fluid, which is the medium at the exit of the steam ejector going to the cold section of the reheater.
What is reheated steam ejector?
The reheated steam is direct heat exchanged with the cold salt and remains as superheated steam. The high-pressure inlet of the steam ejector is the main steam after the first heat exchange stage, and the low-pressure inlet is the reheated steam after the heat exchange.
