5.2 Boiler
BioFire 500 - 1500
1 Combustion chamber module
2 Heat exchanger module
3 Integrated control
The system is controlled and operated centrally via a user-friendly touch display on the BioFire boiler.
4
Intermediate hopper
The intermediate hopper with fall shaft, double stoker, insertion channel and level sensor.
5
Automatic ignition using hot air fans
6 Burning chamber
It is made of SiC fireproof concrete (Temperature resistance up to 1550°C) with step grate (2 zones) made of solid
cast chromium steel. The fuel-pusher grate intervals and 2 primary air zones are separately controllable. The grate
bars can be changed individually. Furthermore, the combustion chambers have 2 secondary air zones.
7 Standing pipe heat exchanger with integrated turbulators and cleaning mechanism
The heat exchanger surface gets cleaned automatically via the integrated turbulators, even during heating
operation, no manual cleaning necessary.
8 Automatic flue gas and combustion monitoring via lambda probe control
A built in lambda probe, which monitors continuously the flue gas content values, detects fuel quality changes and
ensures optimum combustion and low emission values.
The lambda probe adjusts the necessary fuel amount as well as the primary and secondary air input and ensures
the cleanest combustion, even in part load operation.
9 Frequency converter controlled ID-fan (at cyclone)
with under pressure control in the combustion chamber
10 Ash discharge screw
from the combustion chamber including push rod floor conveyor
11 Ash discharge screw
from the heat exchanger module
12 Ash container with wheels
Enable simple and convenient emptying of the ash. (Central ash discharge is optional)
13 Advance flow connection
on either side
14 Back flow connection
on either side
Opposite the advance flow and back flow connection is the hydraulic connection between the combustion chamber
and the heat exchanger module
15 Efficient heat insulation
for the lowest radiated heat loss
