Natural gas condensing boilers and hot air furnaces increase efficiency over standard hot flue models.
The hot flue gases are led into the chimney via a heat exchanger with manual or automatic cleaning of the reheating surfaces.
The Scotch boiler is a fire-tube boiler, in that hot flue gases pass through tubes set within a tank of water.
The hot flue gas exits the regenerator after passing through multiple sets of two-stage cyclones that remove entrained catalyst from the flue gas.
That causes the bottom of the vertical column of hot flue gas to have a lower pressure than the pressure at the bottom of a corresponding column of outside air.
