Abstract
The outline of a tangentially-fired furnace combustion chamber is arranged to show a representative windbox in one corner of the furnace. The secondary air is disclosed as supplied through one set of vertically tiltable nozzles mounted in the windbox. The secondary air supply conduit is mounted to feed the tiltable nozzles. The secondary air supply conduit section adjacent to the nozzles has straightening vanes forming channels in which independently controlled louvers regulate the total cross-sectional area of the channels to maintain the desired velocity of the secondary air through the nozzles.
