Justification of duct shape between two welded films of a film economizer for deep heat utilization

We justify 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 Eugen Kezlia PhD. It is 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.

W artykule dokonano oceny kształtu kanału z uwzględnieniem określonych parametrów. Zaproponowano algorytm pozwalający zoptymalizować dotychczasowe właściwości kanału w aspektach teoretycznym i praktycznym.
