Vertical Cross Tube Boiler Diagram - the Sugar Loaf Inn

Circulation in boilers is largely due to the thermosyphon effect, which is encouraged by the vertical rise of the water-tubes. As the simple cross-tube boiler has near-horizontal tubes, circulation is poor. To improve this, designs such as the Clarke Chapman 'Tyne' boiler used steeply angled main tubes and small vertical tubes at the sides. This improved circulation, although it made washout difficult.
