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. 1914 edition. Excerpt: ...operation, as will be shown later. Types of Tubular Boilers. Tubular waste heat boilers as applied to water gas sets are of either vertical or horizontal type. These are neither strictly vertical nor horizontal--the so-called "vertical" boiler having its tubes set at an angle of about 10 degrees to the vertical, and the tubes of the "horizontal" boiler being inclined at an angle of about 10 degrees to the horizontal. In the case of the vertical boiler, this is done to get better circulation of the water, and to prevent the formation of steam pockets on the top crown sheet where the hottest gases enter. In the case of the horizontal boiler, the tubes are inclined to give better circulation of water, and to allow any liquid matter, which may be condensed from the gases, to run down toward the lower end of the boiler tubes and out of the tubes if possible. The Vertical Boilers are used to recover heat from blast gases only. The Horizontal boilers may be arranged to recover heat from both blast and illuminating gases of a single set in the same boiler or in two boilers, one for blast and one for illuminating gases, or for recovery of heat from blast gases only. Operation of Single Waste Heat Boiler for Both Gases. This is the earliest successful type of waste heat boiler as applied to water gas sets. A single boiler is connected to a single set as described above. The superheater stack valve, wash box and superheater wash box connection of the set are installed as usual. The boiler is connected to a second wash box, which is in turn connected to the foul gas main via the regular scrubber. This is made exactly like an ordinary wash box and comes into action when illuminating gas is being made and passed through the boiler....show more
