Condensing boilers direct-vented exhaust a concern

Nov 01, 2002 · Simple modification can be made to redistribute the air and correct existing air unbalances. These modifications require the knowledge of the existing flow pattern in primary air-inlet system. Conventional engineering analysis rely heavily on empirical correlations and experience to develop boiler and auxiliary equipment designs.

Staged combustion - Wikipedia

Retrofitting over-fire air on an existing boiler involves water-wall tube modifications to create the ports for the secondary air nozzles and the addition of ducts, dampers, and the wind-box. This technique is currently used in 116 pulverized coal-fired units on a total capacity of 50 gigawatt electrical (GW e ) as a standalone measure.
