The Belleville boiler is a type of steam boiler developed in 1850 by the French engineer Julien Belleville . This type of boiler was widely used in the late 19th and early 20th centuries, first by the French navy and later in other countries, to drive steam ships and stationary steam engines.

The automobile manufacturer Delaunay-Belleville later emerged from the inventor's boiler construction company .

Structure and functionality

It is a water-tube boiler in which the evaporator tubes (initially cast iron, later drawn steel) run almost horizontally (approx. 3 ° inclined) through the combustion chamber above the grate . Two pairs of tubes, one on top of the other, are connected laterally outside the combustion chamber via a small water chamber, so that the levels are connected in series in a zigzag arrangement. On the side of the evaporator section is the drum , above which, in later models, a feed water preheater (economiser) with horizontal pipes is attached.

As a water tube boiler, the boiler had over the at that time very common shell boilers that upon failure of the great advantage of the pressure shell only a single pipe was affected, so it is not a boiler explosion came, which was a major step forward for the safety of the boiler operation.
