6 FAQs about [Extraction steam energy storage]
How does a steam extraction system work?
A steam-extraction system was developed to adjust the power output during a low-load period. The incorporation of molten-salt energy storage enables the decoupling of the boiler from the turbine, thus enabling the regulation of the output power during low-load operation.
Does extraction steam mass flow rate affect thermal energy storage capacity?
Both the high-pressure section capacity and plant capacity are positively correlated with the extraction steam mass flow rate. Therefore, the thermal energy storage capacity is primarily determined by the extraction steam mass flow rate. Interestingly, the HSC change rate was greater for higher extraction steam mass flow rates.
How long does a steam extraction system last?
In addition, when the extraction of main steam is <250 t/h, the payback time of the system will exceed 15 years, at which point it will be challenging to meet the economic viability of the retrofitted system.
What is the optimal steam extraction rate?
The optimal solution was achieved for a steam-extraction rate of 237.44 t/h, hot-tank temperature of 686.54 K, and split ratio of 0.78. The optimization results demonstrate that heat consumption and peaking capacity can reach 14.48 MJ/kWh and 73.54 MW, respectively.
Does steam extraction ratio affect exergy loss rate?
Conversely, the exergy loss rate of the other components in the boiler subsystem decreases with increasing the steam extraction ratio, which results from the excess energy of the flue gas shifting to the MSHs. Fig. 12.
Can latent heat storage be used in industrial production of superheated steam?
Our study demonstrates the feasibility of using latent heat storage in the industrial production of superheated steam. Thermal energy is used for residential purposes, but also for processing steam and other production needs in industrial processes.
