Abstract
A furnace and associated heat storage assembly includes a firebox arranged within a rock storage area that incorporates a recirculating flue arrangement for returning unburned gases to below a fuel grate for mixing with fresh inlet air. The rock in the heat storage area is heated by conduction of heat from the firebox, circulating flue gases and a smoke exhaust flue. Inlet air is preheated. An open grate arrangement provides for efficient burning of solid as-producing fuel. A system for circulating air and/or liquid through the rock can be provided, as can a water storage tank.
