The boiler barrel is composed of threerings, the first of which is tapered. Thisincreases the diameter from 76 ins. at thefront end, to 85j4 ins. at the dome ringThe longitudinal seams are on the topcenter line. They are sextuple rivetedand welded at the ends, in accordancewith the regular practice of the feed enters the boiler on the topcenter line, 20 ins. back of the front tubesheet.
