The transfer of heat through metal depends upon the actionof the hot and cold bodies on either side of the metal. If thereis a slow circulation, or no circulation, a small quantity of heatwill be transferred. If the water circulates freely and rapidly,more water comes in contact with the surface in the same timeand more heat is transferred. If the heat is applied to the under side of a vessel containingwater, the water will be rapidly heated. If the same heat is fig. expansion and contraction of each unit, scale will not adhereto firebox sheets. HEAT ABSORBED FASTER. The corrugations of the interior walls of the firebox cause heatwaves to be deflected into small eddies (Fig. 6-e) on the sheets,thus giving the heat units more time to pass through the sheetinto the water and also scouring the soot off the sheet.
