Seite 7 - ... tests indicate the necessity for using metal reinforcement in concrete walls to distribute the effect of the expansion. "The fact brought out most clearly by these tests is the low rate of heat transmission of Portland cement concretes and mortars. This is one of the desirable qualities in buildings intended for fire-proofing purposes. For marking the cement blocks, linen tags were fastened by wire nails to the interior walls at the time of molding. Most of these tags remained in place during...
Seite 9 - ... the fuel bed, and a great drop from the furnace to the uptake indicates a high resistance to the flow of gases through the boiler proper. This law, which in some respects is similar to Ohm's law, as applied to problems involving the electrical resistance of conductors, may be stated as follows: (a) If the resistance to the flow of gases remains constant the pressure drop through any portion of the path of the gases will have a constant ratio to the total drop from the ash pit to the uptake. Thus,...
