Fig. 383. Fig. 383 shows a locomotive boiler in section, with some of the detail of steam supply and exhaust tubes, safety valves, tc. This, however, differs from Fig. 358 in having a domed steam chamber on the top of the boiler, about the middle, from whence the supply-pipe to the cylinders is taken, and to which the safety-valve is fixed. An auxiliary safety-valve is shown over the fire-box similar to Fig. 369. The majority of engineers favour the use of this domed chamber, as will be seen from the following: examples, but it is not of absolute necessity for the engine's actual efficiency. No locomotive boilers are arranged to quite fill with water, although it is very necessary that the level be kept above the internal tubes. This admits of a sufficient steam generating chamber, but as from ebullition and other causes the water is agitated violently, the dome allows of the ent...
