1.3.2. CHIMNEY FUNCTION
Among all the meteorological and geographical factors that influence the
chimney function (rain, fog, snow, insolation period, etc.)
the wind is most
certainly the crucial one
. Apart from the pressure caused by the
temperature difference between the flue gases and the outer chimney air,
there is another type of pressure
–
wind dynamic pressure.
