Abstract
In recent years, the re-burn process has been incorporated in the design and
development of stoker boilers to reduce the emission of NOx from such boilers
in an attempt to preserve the clean air environment. In this paper, we
use the existing modelled governing equations for turbulent fluid flow, laden
with wood/sludge particles, along with the transport equations for different
species to numerically investigate various mechanisms responsible for NOx
production. These equations are simulated using the Fluent software to
conduct a detailed study on NOx production under different operating conditions
for boiler, after incorporating a new method for the re-burn process.
This new method is known as
