All
multi fuels burner operate on a simple principle known as fire triangle.
Air
for burning supplied by the onboard fan that controlled by computer.
Once
the desired temperature achieved, fans turn off and close the air vents
As
the result, air supply becomes very limited and the burning stops.
If we eliminate one side of the triangle, the burning will stop.
Once
again, if the temperature in the system drops fan will activate and burning
will resume.
This
prose is very efficient on the fuel and one bucket of coal can last up to 8
hours.
All
the burning controlled by on board programmable computer.
That
is why the burner have very high efficiency.
In
addition, several tunnels in the burner prevent heat from escaping directly in
to the chimney.
Start Up Fuel Consumption
It is important to understand that in
order initially to heat up the system a lot of energy is required therefore
there will be much greeter fuel consumption at the begin.
Maintaining Fuel Consumption
Let us presume that the temperature in
the system is 17 °C in the system and desired temperature
is 60 °C +/-5 °C. At the begging
burner will use up much more fuel initially to heat up water to 65 °C from 17 °C there is almost 50
°C interval. It takes much less energy to maintain 10
°C interval. Alternatively,
the user may choose different interval.
Calculations
The
multi fuel burner 23 kW burned 35 bags of ruff slack coal in one winter.
Price
of one bag is 7 euro per 40 kg
35*7
we get €245 per one winter
The
average temperature of the house was above 21.5 degrees Celsius.
The
burner was running 8-12 hours daily on a low temperature in the system the optimum
temperature to be around 55-65 degrees Celsius (In the system).
Disclaimer
Every house is diffident
and every house have different quality of insulation. Number of factors effect
efficiency and fuel consumption from number of radiators and temperature
outside. In general, the average cost for the burner to operate is around 24 - 60
cents per hour. It all depended on the quality of fuel type of fuel.
Calculations based on the 23 kW Biodala in semi-detached house fully insulated with Double glazed windows.
