(SCREEN) WITH TUBES WELDED ON THE OUTSIDE

A formula for calculating the temperature distribution 
over the width of a fire sheet with water-cooled tubes welded on the 
outside with boundary conditions of the second and third kinds has 
been obtained. The heat flux from incandescent combustion products 
is incident on the interior surface of the sheet. A strong influence 
on the overheating of the sheet at the center of the gap between the 
tubes is exerted by the step between by tubes, the heat flux incident 
on the sheet, the thickness and width of the weld, and the thermal 
conductivity of the metal. The thermal resistance of the heat transfer 
from the tube wall to boiling water is low; therefore, it is of little 
importance.
