Object number: NG-MC-533

Model of a tubular boiler with a telescopic funnel, painted brown and black.

At the front, two doors are indicated at the sides for the smoke box and three doors in the middle for the furnaces, with openings for the ash pans underneath; the rear is open. The model has 176 tubes. On top of the boiler the telescopic funnel is positioned, operated with a tackle with two worm screws. The fixed part of the funnel has an outer and an inner wall, the moving section being the inner one. The outer funnel wall can be removed. The conduit from smoke box to funnel can be closed with a valve at the base of the funnel. No points of junction for the steam pipe or other pipes are indicated on the model.

This model was made at the Koninklijke Fabriek P. van Vlissingen & Dudok van Heel in 1855.¹¹J.M. Obreen, Catalogus der verzameling modellen van het Departement van Marine, The Hague 1858, no. 534. The use of tubes in this kind of boiler, in which the steam was heated, diminished the volume of the boiler, which enabled it to be placed below the waterline. When sailing, the funnel was retracted to reduce drag.

The 19-gun sloop of war Borneo, 51 metres long, designed by Lambertus Katharinus Turk (1811-1873), was laid down in Rotterdam in 1845. Because of the closure of the Navy dockyard in Rotterdam, the sloop was taken apart and finished by P.A. Bruin in Flushing from 1850 to 1855, where it was renamed Prinses Amalia and equipped with auxiliary steam propulsion. The engines were made by the Koninklijke Fabriek P. van Vlissingen & Dudok van Heel in Amsterdam. Borneo was decommissioned in the Dutch East Indies in 1875.²²A.J.
