Thermal and Mechanical Properties of Two Sensible Energy Storage Materials (Firebrick)

The thermal and mechanical properties of two sensible energy storage materials (Firebrick) were investigated. The properties examined were compressive strength, bulk density, porosity and thermal conductivity. The compressive strength results of the two sensible thermal storage materials (STSM) A and B were 8.82 and 9.79 MPa, respectively. The bulk density values for the STSM A and B were 1740 and 1920 kg/m3, respectively. Also, the obtained porosity values for the STSM A and B were 77.2 and 71.5%, respectively. The STSM A and B thermal conductivity values were 1.27 and 1.76 W/m.K, respectively. The study revealed that both the STSM A and B are suitable for sensible thermal energy storage purposes.
