Basic elements of boiler construction
(User | Installer)
The water body is made as a welded structure from approved steel sheets P265GH with a thickness of 5mm (for
furnace elements) and S235JR with a thickness of 4mm (for water jacket elements)
The automatic feeder delivers fuel (pellets) to a pellet burner located in the combustion chamber at the side of
the boiler. A ceramic plate is placed in front of the burner, steel screens are placed in the rest of the combustion
chamber.
The convection part of the boiler consists of horizontal water channels with flue gas swirlers. The boiler
exchanger is insulated with mineral wool covered with a thin-walled sheet. The insulated bottom of the boiler is
not water cooled.
The flue gas flue with diameter
ɸ
zew = 180mm (in 15, 20, 25, 30 kW outputs) does not have a damper.
The ash pan for combustion waste is located under the burner. The steel door is lined with insulating panels on
the inside.
The boiler is equipped with boiler water supply and return connections of diameter
G 1 ½", water drain connection diameter G ¾", connection for boiler temperature sensor and STB. The boiler
operation and combustion process is controlled by a microprocessor controller.
