After passing through the vapor separator on its way to the second effect tube nest, the vapor generated in the first effect evaporator passes through the first effect vapor feed water heater, where part of the vapor is condensed giving up its latent heat of vaporization to the feed water passing through the tubes of the heater. Likewise the second effect vapor is partially condensed...

Página 576 - More extended experience is necessary before the range of 800 deg. and over is attempted in a commercial installation c With the completion of the Steam Table Research it will be possible to calculate accurately just where the possible limits of economy in pressure and temperatures may be located. At the present time the uncertainty of all values above 200 lb.

The deposit of scale on the tubes retarded the passage of the heat through the tubes making it necessary to increase the pressure and therefore the temperature of the steam in the tubes in order to maintain plant capacity. Therefore, whenever the designed limit of pressure was reached, the plant had to be shut down, the coils pulled out and the scale removed from the tubes. This scale was very difficult to remove, so that the operation of scaling was very tedious and frequently...

Página 561 - C, and aged thereupon at temperatures from o to 200° C, the hardness and, at least at lower aging temperatures, the ductility increase. The actual values of hardness and ductility thus obtained depend upon the quenching temperatures ; they increase with that temperature up to about 520° C, corresponding to the increase of CuAl2 in solid solution. At this temperature any free CuAl2 melts as a eutectic and the material is spoiled; this eutectic temperature therefore marks the upper limit of the useful...
Página 561 - CuAl, melts as a eutectic and the material is spoiled; this eutectic temperature therefore marks the upper limit of the useful quenching temperature range. In order to develop the best mechanical properties by heat treatment, a quenching temperature should be used as near this as is possible without running risk of burning the metal by the melting of this .eutectic. In practice it should...
