Abstract

Boiler has a small water tank with inlet at the bottom. Small bore water tubes connect to large water tubes arranged in a circle near the insulated wall round the main combustion area, going upwards to end in a steam collecting drum with a hot water outflow. On top of the boiler is an oil burner, and waste gas exhaust. The top of the large tubes, may have valves. The burner points downwards heating the main combustion area, pre-heating the water tank, and the hot gas is directed upwards through riser tubes, within the large tubes. Heat output can be controlled by shutting down some of the top mounted valves. A variation of the boiler can have the burner at the bottom using solid fuel. Special covering for the combustion area is unnecessary as the water tubes surround it. The outside cover keeps cool, and has low condensation at low output.
