Product description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1915 edition. Excerpt: ...in the boiler, the vapor commences to rise from the water in it and to flow through the main supply pipe into the radiators. As the vapor enters the piping the air is forced ahead of it and discharged from the radiators through the bafflers into the air and returp line. From there it is ejected from the system through the. controller, the controller at this time acting as a large air valve for the entire system. As soon as the heat enters the brass expansion tube of the controller it expands and closes the exhaust opening; this action closes the system against the pressure of the atmosphere. The system is now filled with vapor or steam and when the drafts of the boiler are closed the system is placed under a vacuum by reason of the action of the controlling device and all radiators will continue to give off heat as long as there is any vapor present in the system. Immediately more heat is provided at the boiler by opening the drafts, the vapor or steam generated flows uninterrupted through all the piping and radiating surfaces. The system is very simple in operation. The flow of vapor through a radiator is illustrated by Fig. 124. The vapor enters at the top of one end of the radiator, passes to the opposite end and condenses as it settles toward the bottom of each loop. Fig. 125 illustrates the-manner of piping and general method of installing the Kriebel system. ATMOSPHERIC AND MODULATED SYSTEMS. i. Q. What system is known as the "Atmospheric system"? A. The Adsco system of the American District Steam Co. 2. Q. Describe this system and its method of operation. A. This system is adapted for use with the one-pipe circuit or regular one-pipe gravity method of piping. It is not a vacuum system as no vacuum principles are applied. It is...
