In a combustion air supply system, particularly a secondary air supply system for a recovery furnace, the secondary air inlet ports are divided into two arrays in such a manner that the combustion air coming in through the inlet ports of the first array is directed in part to contact and in part to by-pass a central region in the outer surface of a carbonization layer. The combustion air coming in through the inlet ports of the second array is directed to by-pass the combustion air coming in through the inlet ports of the first array thereabove. The first and second arrays are located on the opposite walls of the combustion chamber, preferably on the front and rear walls. The recovery furnace further comprises a primary air supply zone for blowing combustion air onto the sides of the carbonization layer and a tertiary air supply zone above a waste liquor inlet. |
