solar thermal energy with molten salt Storage for residential heating application
Energy Procedia, 2017Co-Authors: Zhihang Zhao, Mohammad Taufiqul Arif, Amanullah M T OoAbstract:Abstract Heating application is one of the areas in residential building where residents pay a significant part of energy bill. Thermal energy from solar irradiance can be collected by solar thermal collector (STC) and absorbed by heat transfer fluid (HTF) to transport heat to the heat-exchanger and to the load. This paper investigated various solar collectors and considered parabolic trough collector (PTC) to develop a residential heating application. The system structure mainly consists three Subsystems: solar thermal absorption Subsystem, thermal energy Storage Subsystem and underfloor heating Subsystem. Because of temperature range and specific heat capacity Nitrate salt (0.54KNO3+0.46NaNO3) was considered in the model. A typical house in Melbourne with heating area of approximately 240m 2 is considered as thermal load. Model was evaluated for summer, winter and yearly load demand and result showed that molten-salt Storage helped the system to operate consistently even at night-time (19:00 – 05:00) without solar radiation.

system level simulation of a solar power tower plant with thermocline thermal energy Storage
Applied Energy, 2014Co-Authors: Scott M Flueckiger, Brian D Iverson, Suresh V Garimella, James E PachecoAbstract:A thermocline tank is a low-cost thermal energy Storage Subsystem for concentrating solar power plants that typically utilizes molten salt and quartzite rock as Storage media. Long-term thermal stability of the Storage concept remains a design concern. A new model is developed to provide comprehensive simulation of thermocline tank operation at low computational cost, addressing deficiencies with previous models in the literature. The proposed model is then incorporated into a system-level model of a 100 MWe power tower plant to investigate Storage performance during long-term operation. Solar irradiance data, taken from measurements for the year 1977 near Barstow, CA, are used as inputs to the simulation. The heliostat field and solar receiver are designed with DELSOL, while the transient receiver performance is simulated with SOLERGY. A meteorological year of plant simulation with a 6-h capacity for the thermocline tank Storage yields an annual plant capacity factor of 0.531. The effectiveness of the thermocline tank at storing and delivering heat is sustained above 99% throughout the year, indicating that thermal stratification inside the tank is successfully maintained under realistic operating conditions. Despite its good thermal performance, structural stability of the thermocline tank remains a concern due to the large thermal expansion of the internal quartzite rock at elevated molten-salt temperatures, and requires further investigation.
