FRONTS--Ornamental fronts are fitted to the front supporting frame. These have large doors for access to the front headers and panels above the fire fronts. The fire fronts where furnished have independent frames for fire doors which are bolted on, and ashpit doors fitted with blast catches. The lugs on door frames and on doors are cast solid. The faces of doors and of frames are planed and the lugs milled. The doors and frames are placed in their final relative position, clamped, and the holes for hinge pins drilled while thus held. A perfect alignment of door and frame is thus assured and the method is representative of the care taken in small details of manufacture. The front as a whole is so arranged that any stoker may be applied with but slight modification wherever boilers are set with sufficient furnace height. [Illustration: Cross Drum Boiler Front] In the vertical header boilers large wrought-iron doors, which give access to the rear headers, are attached to the rear supporting frame. [Illustration: Wrought-steel Inclined Header Longitudinal Drum Babcock & Wilcox Boiler, Equipped with Babcock & Wilcox Superheater] [Illustration: Automatic Drumhead Stop and Check Valve] FITTINGS--Each boiler is provided with the following fittings as part of the standard equipment: Blow-off connections and valves attached to the mud drum. Safety valves placed on nozzles on the steam drums. A water column connected to the front of the drum. A steam gauge attached to the boiler front. Feed water connection and valves. A flanged stop and check valve of heavy pattern is attached directly to each drumhead, closing automatically in case of a rupture in the feed line. All valves and fittings are substantially built and are of designs which by their successful service for many years have become standard with The Babcock & Wilcox Co. The fixtures that are supplied with the boilers consist of: Dead plates and supports, the plates arranged for a fire brick lining. A full set of grate bars and bearers, the latter fitted with expansion sockets for side walls. Flame bridge plates with necessary fastenings, and special fire brick for lining same. Bridge wall girder for hanging bridge wall with expansion sockets for side walls. A full set of access and cleaning doors through which all portions of the pressure parts may be reached. A swing damper and frame with damper operating rig. There are also supplied with each boiler a wrench for handhole nuts, a water-driven turbine tube cleaner, a set of fire tools and a metal steam hose and cleaning pipe equipped with a special nozzle for blowing dust and soot from the tubes. Aside from the details of design and construction as covered in the foregoing description, a study of the illustrations will make clear the features of the boiler as a whole which have led to its success.
