Design

A nice compact Marine type centre flue boiler. The small design means that only a small amount of water is held requiring some form of automatic water feed pump being fitted to the engine.Water is fed into the boiler via the valve mounter on the side towards the chimney end. To ensure dry steam a large dome is fitted with mounting points for 3 steam connections. A seperate safety valve connection is fitted halfway along the boiler. The dome also mounts the top end of the water gauge, impportant because the boiler is such a small diameter there is no room to mount a water gauge on the end of the boiler. The central flue is mounted towards the bottom of the cylinder and has 16 cross pipes for increased heating sureface, mounted directly in the flame provided by the brass burner. The flue is extended beyond the end of the boiler and a short pipe is braised onto the top for attachment of a chimney. This type of boiler uses a small amount of water and boilers it very quickly, the water needs to be replaced continuously. This boiler is ideal for smaller steam powered launches having a low centre of gravity.
