Simultaneous reduction of NOx and CO emissions in domestic decoupling coal-fired stoves
A typical civil decoupling coal-fired stove has two parallel furnaces
called a pyrolysis chamber and a combustion chamber
which are connected at the bottom
coal is introduced from the upp
er part of the pyrolysis chamber
and air is introduced through the inclined grate at the bottom of the pyrolysis chamber. Based on the profound understanding of both the nitrogen transformation route in coal combustion and the characteristics of gas flow circulation in decoupling stoves
the mechanisms of simultaneous reduction of NO
x
and CO emissions in domestic decoupling coal-fired stoves were qualitatively analyzed in this paper. The influences of draft type and coal property on NO and CO emissions were experimentally studied further. The results indicate that the simultaneous suppression of NO
x
and CO emissions in a domestic decoupling coal-fired stove can be mainly attributed to its unique geometry structure and draft type. Burning clean briquettes in decoupling stoves helps to reduce pollutant emissions significantly.
