The Gas Age Volume 42 (Paperback)


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. 1921 Excerpt: ...Gas set with two 6 ft. 6 in. sets to help out when necessary. Avoiding Back Pressure on Machines The installation of an additional and larger machine required several changes in equipment at the Plant. The relief holder is about 250 feet from the generator house and the gas was delivered from the water gas machines to the relief holder through a 16 in. underground pipe. Operating the 8 ft 6 in. set to capacity under these conditions, put a very appreciable back pressure on the machine. Increasing the amount of gas delivered through this pipe line would have caused excessive back pressure. This problem was solved by the installation of an overhead, welded steel pipe from the machines to the relief holder extending directly downward at the relief holder to connect with the underground inlet pipe to the holder. The over head pipe is 30 in. in diameter and made of J4m-material. To further reduce the possibility of excessive back pressure a connection was made between the inlet and outlet pipes of the relief holder. This connecting pipe line was equipped with a valve so that it could be shut off if desired. The overhead pipe has so much condenser effect that it has so far not been necessary to open the connecting line during normal operation. It may, however, he used advantageously if the inlet pipe to the relief holder should happen to be stopped up. The back pressure on the seal of the largest water gas set has so far not exceeded 13 in. of water column. Condensation in Works Main On account of the great distance between the generator house and relief holder, there is a possibility of the accumulation of large quantities of condensation in the connecting pipe line. In order to eliminate difficulties from this source the overhead pipe was so installed that one-...
