A quick back of the envelope calculation:
A 6.5 feet by 6.5 feet cube (2mx2m) could store about 4500kWh at 1000C, this seems close to energy need for heating for more than a month ( Energy density of fireclay from here: https://www.engineeringtoolbox.com/sensible-heat-storage-d_1217.html https://www.engineeringtoolbox.com/sensible-heat-storage-d_1... ).
That's a very large amount of bricks and a potentially dangerously high temperature but still...
Pottery kiln manufacturers might be able to design this? Kilns go to higher temp than this and are used indoors.
- pfdietz 5y agoFirebrick energy storage has been proposed! If one uses SiC bricks, which might act as their own resistive heaters, one could operate up to 1800 C.
- BenoitEssiambre 5y agoThat's cool if the bricks themselves can be resistive heaters. You might burn elements pretty quickly at those temps.
- pfdietz 5y agoRight. The ordinary firebrick system with separate heaters would be limited to about 1000 C, although I've seen a concept using sand flowing through a heater that would reach 1200 C.
