Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1910 edition. Excerpt: ...the new vertical centrifugal washer of Messrs. Kirkham. Hulett, and Chandler. The last named is very similar in its action to the Feld washer. Gas Governors: In the works the retort-house governor is coming into general favor. It ensures greater uniformity of gas. The use of district governors to regulate the pressure to consumers' meters is also being extended with beneficial results. Gas Calorimeters: The "Boys" calorimeter was introduced by the Metropolitan Gas referees in 1905. It agrees closely in results with the Junkers and Simmance-Abady instruments and possesses peculiar advantages of its own. Pyrometers: Of new instruments the Wanner electrical pyrometer is largely used in Germany. The Fery radiation pyrometer is in greater favor in England and France. The latest modification is the Fery radiation--piral pyrometer--a very simple and compact mechanic! capable of taking temperatures of combustion chambers and retorts with the greatest convenience and celerity. Recorders: Pressure. In a gas works it is highly desirable to have a record of pressure or vacuum at inlet of retort-house governor, inlet of exhauster, inlet of purifiers and outlet of holder. Every well-equipped works takes daily records of this kind. Carbon Dioxide: Daily records of carbon dioxide in the waste gases from boiler furnaces, in crude carburetter! water gas, or even in waste gases from retort settings, are of great assistance in controlling manufacture. Several ingenious contrivances for this purpose are now supplied. Calorimetry: One of the latest advances is the recording calorimeter. Junkers' firm supply an elaborate and accurate calorimeter recording gross value. Messrs. Parkinson and Cowan supply a very simple mechanism which records net value....show more
