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.
