Babcock and Wilcox Boiler Model

This is a half-size model of the boiler that won the award for sectional steam generators at the Centennial Exposition in Philadelphia in 1876. It was in service until recent years and is now preserved by the Babcock and Wilcox Co., the makers.
The boiler represented is a hand-fired, inclined-tube boiler, with two parallel longitudinal drums connected by a cross steam drum. The headers are of the earliest type of cast-steel sinuous header and are seven tubes high. The boiler is suspended from two cast-iron arched beams that rest upon the side walls of the brickwork. The highly ornamental cast-iron front is trimmed in gold paint. The boiler is equipped with a ball-and-lever safety valve, three water-level sight gauges, and a pressure gauge.
The Centennial boiler was sold to the De Castro and Donner Sugar Refinery in Brooklyn, New York, after the exposition and was continued in service through the early 20th century.
This description comes from the 1939 Catalog of the Mechanical Collections of the Division of Engineering United States Museum Bulletin 173 by Frank A. Taylor.
