Since there is no distinct bed level and a CFB. The density of the bed is controlled, rather than the depth as in a BFB boiler. Combustion air is usually supplied at three elevations in a recovery boiler furnace called primary secondary and tertiary. Three levels in furnace. Forced draft fan controls flow of combustion air to boiler.
