ATTENTION!
Boiler – is a steel cylinder, enveloped in a larger diameter steel cylinder, which provides
thermal insulation. Heated water resides between these two cylinders. There is a draft
regulator on the front side of the boiler (2) (see 7.3). The construction has fuel loading (8),
ash removal (11 openings and a smoke outlet (5), as well as water supply (14 - 15),
thermometer (16) and pressure relief valve (17) openings. An air heating chamber is
installed in the upper part of the combustion chamber to improve the combustion quality and
heat transfer (4). The chamber holds a telescopic air supply pipe (7), at the end of which an
air distributor is attached (9).
"U'' boiler, is designed to burn peat briquettes or coal, has a switch valve (6),
complemented with fire grate (19) and air injection collector (21).
