(USER/INSTALLER)
The water tank’s body is made as a structure welded from certified P265GH steel sheet of a
thickness of 6mm (for elements of the furnace) and S235JR steel sheet 4mm thick (for elements of
the water jacket).
The automatic feeder supplies fuel to the retort burner situated on one side of the boiler, in the
furnace chamber. A ceramic plate is situated above the burner, and steel shields line the remaining
part of the furnace chamber.
The boiler’s convective part is made up of horizontal water channels in which air swirlers have
been placed. The boiler’s exchanger is insulated with mineral wool shielded by a thin-walled sheet.
The boiler's insulated bottom is not cooled by water.
The flue, with a diameter of
ɸ
ext = 160mm (for powers 15, 20, 25kW) (SMART ECO-CARBON 30
=180mm), does not have a damper.
The ash pan for waste material from the furnace is situated under the burner. The steel door is
lined with insulating panels from the inside.
The boiler is equipped with connector pipes: feed and return for boiler water with diameter G 1
½”, water drain pipe with diameter G ¾”, connector tube of regulator sensor and STB. A
microprocessor-based regulator controls the boiler’s work and the combustion process. Schematic 6.1 Basic elements of the boiler SMART EKO-CARBON
