Get A QuoteThe chimney's working is based on the natural draft or stack effect. As we know, the density of a gas reduces, with rising in its temperature, so because of this reason when the flue gases enter the chimney, the buoyancy forces of air come into action and help in carrying the flue gases out of the chimneys. In the case of a Boiler assembly employing an Induced Draft Fan, the flue gases are
