ABSTRACT
We justificate a shape of a duct between two welded film sheets in economizer, developed at the Heat Gas Supply and Ventilation Department of Kyiv National University of Construction and Architecture by PhD. Eugen Kezlia. Analytically proved that idealized section of the channel is digonal. It is formed by two arcs of the same radius. We offer an algorithm for approximating an experimental duct shape that provides equal section area, perimeter, and equivalent diameter.
