Investigation of Temperature Fields of Tube Sheets in Gas Tube Boilers.

Using the method of electromodeling, the temperature conditions of a tube sheet element separated from it by symmetry planes is investigated. The element is situated in the central part of the sheet, sufficiently far removed from its edges and includes not only the tube sheet but also the tube connected to it. The effect of the heat transfer conditions on the gas side and of spacings between tubes is investigated. To make it easier to transpose the results obtained to other conditions, they are presented also in a generalized form.
