Abstract

1350093 Boiler flues H B SMITH CO Inc 7 June 1971 19154/71 Heading F4A A boiler has parallel heat exchange flues connected to a supply flue S and a discharge flue D, the cross-sectional area of the flue D being less than that of the flue S to such an extent that equal quantities of gas flow through each heat exchange flue in unit time. In order to achieve this the cross-sectional area N 6 of flue D, and the cross-sectional area N 1 of flue S, are chosen so that: where # 1 and # 6 are the densities and T 1 and T 6 are the absolute temperatures at points 1 and 6 respectively.
