Steam generator, horizontal semifixed
type to tubes from smoke to three turns, suit of dome, pressurized,
type STF 0
Tubes slabs broadsides are towards the hearth
that towards the plating, reached or joints of expansion on the
hearth; with these constructive characteristics the various
expansions of the hearth and the plating come absorbed from the
parts curves and they do not weigh on on the weldings or the flat
parts of slabs to tubiere with consequent crack of fatigue of the
Bordered tubes, weldings are avoided therefore on
slabs and therefore a hardening of the material; the possibility of
an easy extraction of the tubes bundle is had moreover, if this
became necessary after several operation years
Wide combustion chamber and low thermal cargos
(1.000.000 - 1.200.000 Kcal/m³h) so as to not to subject the body
boiler to temperature stresses that limit the duration of the same
Combustion pressurized with values in combustion
chamber that vary from a minimum of 30 milimeter of 100 H²O
to one max of milimeter of H²O to second of the types of
boiler, fuel and cargo.
Combustion efficiency 90÷92%.
Losses for lessened radiation reduced (2-3%) for
the use of non-conductor materials are on the plating that on
smokeboxes (the fiber glass, refractory ceramic fiber, pastes,
insulators briks) of remarkable effectiveness.
Possibility of several fuel employment: gas
methane and others, diesel oil, fuel oil.
Contained specific production (35 Kg/h), width
room and vapor dome avoid tumultuous vaporizations and allow one
vapor production much dry ground (title it of vapor 0,97);
remarkable a specific ability (approximately 2 lt/Kg vapor) concurs
accumulates of such vapor to avoid lowerings of pressure during the
demands for tip.
The generator comes supplied in the version
monoblock, suit of taps of best houses (KSB, BONT, KLINGER) electric
pump of feeding-injector-regolator of level to floater (attack and
detaches electic pump of feeding, block burner to level minimal) -
probe block burner to the minimal level with manual rearmament
pressure switch of block with rearmament operation-picture
handbook-pressure switches electrical worker control with
connections to the several equipment.

In the generating saying planning it has been
attempted to render elementary is the use that the maintenance,
equipping it of simple but at the same time reliable equipment.
Smokeboxes are easy removable and they are
equipped of revolving arms, for being able to render the hearth and
the tubes bundle for cleaning, the tests and eventual extraordinary
reviews after operation years visible.
