What creates natural chimney draft?
Natural draft is generated by the difference in density between the hot flue gas inside the chimney and the colder ambient air outside, proportional to chimney effective height.
Calculate boiler chimney diameter, natural thermal draft (Pa) and flue gas flow velocity according to EN 13384-1 standard.
