6、166, CEN/TC 166/ WG 1 und WG 2). The English term “chimney” generally corresponds to the German term senkrechter Teil der Abgasanlage. In the German version of this standard, however, the term Abgasanlage is used throughout. Amendments This standard differs from DIN EN 13384-2:2009-07 as follows: a)
7、 editorial mistakes have been corrected; b) mistakes in equations have been corrected; c) characteristic values for heating appliances for solid and liquid fuels in Annex B have been adapted to actual data; d) for the mixture of fuels, a clarification about the rise of the dew point has been added;
8、e) for non-concentric ducts the calculation of the mean temperature of the air supply has been amended; f) the process for iteration for appliances with low impact of the pressure to the flue gas mass flow (e.g. CHP with combustion engine) has been simplified; g) for chimney fans, a calculation proc
