This is an OCR edition with typos. Excerpt from book: useful temperatures of fluids for particular elevations can only be ascertained by experience and attention. The boiler should have a recess in its side (Fig.... more » 7). to receive the end of the tube. This recess may project several inches, according to the size of the tube, from the body of the boiler, so as not to be immediately subject to the action of the fire. The fluid in this part will not be much agitated by ebullition in the boiler, but will ascend tranquilly into the machine, and take but few air or steam bubbles with it. An horizontal section of the boiler and recess may be of a form resembling Fig. 8. Or another vessel may be united to the boiler by a short connecting tube of large diameter; and the end of the Thermosiphon may be put into this vessel, instead of the boiler. The three vessels may stand triangular- wise, as in Fig. 9; or they may stand in a straight line, with the boiler A in the middle. In Figs. 9 Sf 10, A is the boiler ; B the vessel to receive the descending fluid; C the vessel to be supplied with hot fluid from A; H the connecting tube, through which the hot fluid runs from A to C; and D the tube, with a stop-cock, E, through which the fluid returns from B to A. In this, or in any other horizontal position of the vessels, if one end of the Thermosiphon be suspended in C, and the other end in B, and the vessels be filled, and also the Thermosiphon in the way already described, it chapter{Section 4may be necessary, when fire is lighted under A, to have recourse to some expedient to raise the temperature of the fluid in C a little; or the Thermo- siphon may not act, unless A and C are near each other. This may be done after the following manner:—First, let the fluid in A be heated; and if this should not cause the Thermosiphon to act, stop the coc...« less
