Also used to fire brick kilns. Had brick plant that was customer at last job; maintenance mgr told me they get several thousand degrees of temp by the flash fire from dumping in sawdust/chips they used. Hauled it in by the 40' trailer load. Also told me they never shut down kiln unless necessary as it took 7-10 days to get it back up to temp once down. Seems it'd do well to heat home.
