Сторінка 10 - D in order to increase the useful section of this orifice, or, we should lessen the quantity of steam of the jet by diminishing the orifice A by the conical rod T. Thus the conditions of the proper working of the apparatus are: 1st. That all of the jet of steam A be condensed by affluent water; 2d. That the temperature of the mixture be lower than the temperature of corresponding saturation at the mean pressure of G. In case that the chamber G communicates with the atmosphere, the temperature of...
Сторінка 9 - The condition that the liquid jet, through the tube EE, is uninterrupted assumes that the jet is at too low a temperature to be transformed into steam at the atmospheric pressure in its passage through the chamber G G. Hence its temperature should be below 100°. Should the temperature exceed 100° the working of the apparatus is imperfect. We are warned by a production of steam which fills up the chamber GG and which escapes by the discharge pipe HH.
Сторінка 72 - The mixture of steam and air is introduced into a reservoir containing bits of coke crushed and washed by a current of cold water. The steam is condensed and the air escapes mostly free from steam. As a means of forcing currents of air for purposes of ventilation this method of M. Siemens is worthy of consideration.
