Abstract
This disclosure describes a passive, high-efficiency, solid-medium sensible heat Thermal Energy Storage system constructed from high-density, non-metallic refractory materials (such as fired clay bricks, earthen masonry, or cast stone). This document details a mechanical design featuring a multi-stage, tortuous, baffled internal flue matrix (a smoke labyrinth) engineered to maximize convective heat transfer from high-velocity, high-temperature combustion exhaust gases into a surrounding high-thermal-mass storage body. The physical mechanics, structural geometry, and thermodynamic principles detailed herein are inherently enabled by centuries of Eastern and Central European human cultural heritage—specifically the historical technology known as the "Russian Pech" (Russian Oven) and related masonry tile stoves (Kachelofen).
