<p>The water boiler with an upright water cylinder (1) and a cylindrical combustion chamber (2) underneath, matching it in shape, has a distance tube (5) between the, supporting the cylinder. A small diameter lower extension (6) of the cylinder is positioned in the centre of this ring, so that it is surrounded by the exhaust gases from the evaporator burner (3) below. A cleaning door is incorporated in the distance tube, and the exhaust pipe (7) is nearly opposite. Between them, in the annular space between the extension (6) and the exhaust pipe (7) is a curved baffle plate (10) which can be slid to one side to simplify cleaning. The small diameter extension allows a small body of water to be subjected to maximum heat for rapid heating up.</p> |
