Built by the Skinner Engine Company, most Unaflow engines are single expansion. These feature tandem high- and low-pressure cylinders separated by a common head. The Badger's four Foster-Wheeler Type D marine boilers, which supply 470-psig steam to the engines, are among the last coal-fired marine boilers built.

Among the fastest coal-fired merchant ships was the four-funnelled 240-metre Mauretania that was completed in 1907. She had steam turbines that drove four propellers (sometimes expressed as quadruple screws) and she could achieve 26 knots. Note the smoke from the coal-fired furnaces. In 1921, her boilers were converted to oil-firing.

The use of tubes for marine boilers was urged by Thomas Cochrane, tenth Earl of Dundonald, who was born in 1775 and died in 1866. The Earl of Dundonald did much to assist the introduction of steam power in the Navy, and he designed HMS Janus, launched in 1844. This warship was equipped with four boilers, each containing three furnaces.
