BioPower and Nokia N900 estimates your solid bio fuel burner power!
BioPower for Nokia N900 is tool to estimate solid bio fuel burner
current input power. It listens
and
visualizes the sound of conveyor detecting the on / off period times
from
the conveyor sound. From conveyor on / off period times the current
input power of the
burner can be estimated. BioPower utilizes the capabilities of N900 in
a clever way to accomplish this task.
Try out BioPower - it's easy!
You may try out BioPower on your N900 even if you don't happen to have
solid bio fuel burner at hand - first download
and install BioPower on your N900, then play sound sample files
from the menu on the left
and let BioPower
listen it right from your N900 device or from your computer speakers!
BioPower screenshots
This is the main screen of BioPower. The conveyor sound is high lighted
with
bright colours. During the high lighted areas in graph, the conveyor is
on.
The lower black area is the background noise.
When the high bars turn to green, the current power of the burner is
displayed as kilowatts on the bottom of the screen along with the
conveyor feed
percentage and on / off period time as milli seconds.
The thin blue line indicates threshold level, that will adapt
automatically to the environment and conveyor noise levels. Threshold
level is used to decide when the conveyor is on or off.
This is the settings screen of BioPower. To get good estimates, the
settings must suit your
conveyor as well as your fuel.
Conveyor production defines
how much fuel your conveyor products during
60 seconds of time. You really need to measure it!
Fuel energy defines the energy
contents of your fuel. For wood
pellets good estimate is 4750 Wh/kg.
Typical period time is the
normal length of conveyor on / off period as milli
seconds.
Filtered display data smooths
the main display graph.
Biopower constraints and some tips
Biopower may be used with burners that feed solid bio fuel directly
from
conveyor to the furnace bed, e.g. there is no small storage for fuel
inside the burner from where the fuel is delivered by secondary screw
conveyor into the combustion.
While using BioPower, try to hold the device so that there is no big
changes in background noise. Also for example speaking may disturb
estimation process.
