Abstract

Narrowed zones has a min. cross section of 30-50% of the cross section area of the furnace in the combustion region, the walls sloping at an angle >=60 (80) degrees. Design improves the combustion of the air in the combustion chamber, giving rise to more uniform combustion over the whole cross section of the furnace.
