Launch-type boiler

A launch-type, gunboat or horizontal multitubular boiler is a form of small steam boiler. It consists of a cylindrical horizontal shell with a cylindrical furnace and fire-tubes within this. Their name derives from the boiler's popular use at one time for small steam yachts and launches. They have also been used in some early Naval torpedo boat destroyers.
