Function principle
2.2.1.
Boiler
The function of the BIOPLEX boiler is
based on natural gas evacuation through
the chimney. The fuel is positioned on the
grate. The combustion takes place in the
fire chamber. During the combustion the
flame comes in contact with the side
walls of the fire chamber, which are
surrounded by water. The fire chamber is
of big volume in order to receive big
dimension logs and to ensure a long
autonomy.
The combustion air is supplied by the fan
and distributed through an air distributor,
positioned below the fuel grate. The
combustion is regulated through the fan,
controlled by the control panel.

Boiler function
The exhaust gases are guided through the heat exchanger to the smoke box, and afterwards
evacuated to the chimney. The smoke box is equipped with an inspection and cleaning door,
which also actions as an explosion relief.
The doors have an insulation cord to ensure air-tight closing. Each door is equipped with a
screwed handle, which must always be well tightened during the combustion. The flange on
the middle door has a rotating clamp, for secondary air adjustment and flame inspection. If
necessary, this flange can be removed, and a burner can be placed in its position.
2.2.2.
Furnace
The BIOPLEX boiler is equipped with the innovative biomass furnace BIOFIRE. The system is
consisted of two axes (BI-AX): The lower axis is the main one, feeding fuel to the furnace,
while the upper is the secondary, transporting the fuel from the silo to the main axis. Between
the two axes there is a safety DROPBOX device. This device has a metal flap that automatically
closes with a spring when the feeding stops. This way the danger of blockage and backfire is
eliminated. The motoreducer is mounted on the lower axis, and the transmission is realized
through chain wheels. A metal protection cover is places around the transmission system.
The combustion air is supplied by the fan mounted on the furnace. In case the optional ignition
system is installed, there is a 500W ignition element
mounted in the air pipe, close to the furnace plate.
