Boilers, Babcock Wilcox types

Types and Features.—Boilers may be classed as horizontal (Heine, loc6-motive) or vertical (Wickes, Manning) fire-tube (horizontal-tubular. Manning, locomotive) or water-tube (Babcock Wilcox, Wickes, Stirling, Heine) exter-... 

All of these boilers lend themselves to flexibility of arrangement. The length of tubes, numbers in a row (horizontally and vertically), etc., may be varied to suit economical or other conditions. Boilers of this type are generally supported independently of brickwork. Standard methods of cleaning have been developed, but a large number of joints must be made after Babcock Wilcox or Heine boilers have been completely opened for cleaning.

Upper drum is for steam disengagement the lower one for accumulation and eventual blowdown of sediment, (b) A two-drum boiler. Preheat tubes along the Roor and walls are cormected to heaters that feed into the upper drum, (c) Cross section of a Stirling-type steam boiler with provisions for superheating, air preheating, and flue gas economizing for maximum production of 550,000 Ib/hr of steam at 1575 psia and 900°F.
