Engberg Steam Engine is designed to extract thepowor from tKe steam you produce before it passes, with little loss In heating value, Into your hooting or processing cydos. The steam engine acts as a reducing valve but lt*s a reducing valve that generates power or drives equipment and then oxhausls most of the heal units Into your processing or hoaling lines. The modem TroyEngborg Steam Engine also offers tho following ad vantages -- wide spoed range, high overload capacity, high starting torque, conservative speed, exceptional depondability. Investigate this drive for your.stokers, fans, pumps, compressors and generators. 2500 TROY ENGINE & MACHINE COMPANY (Established 1870) Railroad Avenlie Tray.

Assuming an efficiency of 72% w get 3.24 million! Btu actually contained b the steam used for curing the concrete blocks. The steam fed to the eylloders it it 12 pel, or 26.7 poia. Wo atsust the team Is dry, saturated and eoDtaiai 1161 Btu per lb. Later daring the process the steam la raised to 100 lb sr 114.7 psia. If the steam U dry and saturated, It contains 1109 Btu per lb. At this pressure end enthalpy (H89), NIP discharges tho steam to beat ib* countryside. My suggestion fa to install a uak and bypass tbe feedwater to it. ft* charge the steam to the tank sad cos* dense it to atmospheric pressure. ErT pound of steam will give up 1189 --1 or 1009 Btu. This will be used to heating the raw feedwater from tbs Detroit River to 212 F. The tank. 1 effect, is now a condenser and a beater. Pump this condensate to the boiler ^ raise the temperature 338*212, which Is 126 F. 1 Yeviteh, Philadelphia p* POWER May ,wl. May 1948
