FOR STEAM ENGINES AND VACUUM PANS.
PARTICULAR MERITS.
I. No water is wasted or consumed, as the condensed water can be used for feeding the boiler, and the same quantity ordinarily employed for boiler feeding suffices for effecting condensation.
II. Hot distilled water is obtained, affording an absolute preventative against boiler incrustation.
III. Very active condensation is obtained with a comparatively small surface, this effect being brought about by the rapid absorption of the heat through evaporation.
IV. A high degree of vacuum is secured, resulting in a great saving of fuel.
V. Hot and impure water can be used for cooling.
VI. The apparatus can be executed to suit the most exacting requirements.
VII. The cooling surfaces are automatically kept clean.
VIII. The condensing passages are easily accessible.
