Abstract

A tangentially-fired furnace is disclosed in enough detail to illustrate the location of injection ports for excess air above the fireball of the combustion chamber to eliminate the swirl of the flue gases as the flue gases flow into the convection section, in order to produce a uniform mass flow and temperature pattern of the flue gases over the cross section of the furnace exit.
