1) Automatic control of the boiler can adjust:
ź
boiler temperature
ź
central heating circulation temperature
ź
hot water temperature
ź
room temperature
ź
temperature of return water from central heating (boiler exchanger
protective feature)
ź
ignition time (depending on type of fuel)
ź
fuel feeder operation time
ź
feeder and vent manual control time
ź
automatic burner power modulation (fuzzy logic)
ź
automatic air feed (lambda sensor module)
2) Temperature sensor
T he STB mechanical protection is situated inside the boiler and prevent
o
the heating system from overheating. it is set by default at 95 C.
if temperature exceeds 95, the vent is turned off. at the same time central
heating hot water pumps come on and the mixer valve opens.
3)Fuzzy Logic control (advantages)
:
ź
advanced algorithm
ź
reduces fuel consuption and lowers the amount of sooth
and contamination in the boiler
ź
enhanced boiler working temperature stability- eliminates
condensation in the boiler (sweating of the boiler)
ź
combustion chamber temperature is high and stable which lowers
carbon oxides emission.
4) Lambda sensor
T he sensor continiously adjusts the amount of air in order to provide
the most efficient operation of the boiler and minimise the carbon oxide
emission under the given boiler load, fuel type and weather conditions.
5) Fumes temperature sensor
T he sensor is situated in the boiler flue. it allows to control the fumes
o
temperature. if the temperature exceeds 250 C, the vent automatically
shuts down until the combustion temperature drops.
6) Mixing valve acutator
With this device you can adjust the set heating circle temperature
in the central heating system, keeping the constant boiler temperature.
The temperature is calculated from the heating curve in relation to
the outside temperature.
The default fuel of boilers equipped with a screw feeder or retort or BIO
burner is hard coal conforming to the parameters outlined in norm 82/G
97001 – 3:
• coal type: 31 or 31.1
• calorific value: 26MJ/kg
• humidity: ≤ 15 %
• ash content: ≤ 10 %
• volatile matter content: ≤ 28-48 %
• sulfur content: ≤0.6%
• softening point of ash: ≥ 1150 ºC
• agglomerating capacity: <10
• granulation 5-32 mm
• dust content <10%
2) Pellets conforming to the parameters outlined in norm EN 14961-2
(C1)/ EN 14961-3(C2) :
ź
calorific value:16,5- 19 MJ/kg
ź
ash content: 0,7 %
ź
density ≥ 60
ź
diameter: 6 ± 1 mm; 8 ± 1mm
ź
length: 3,15 ≤ L ≤ 40
ź
humidity: 10 %
The fuel should be clean and not contain rocks, pieces of wood etc.
With manual stoking, the fuel is deciduous under 20 % humindity and coal
of OI sort. it is not advised to use coniferous logs as they produce a lot of
soot in the boiler, requiring it to be cleaned often.
