VIDEOS ABOUT Q-ROBOT
BENEFITS OF THE Q-ROBOT
✓ Representative samples randomly from
each truck / train wagon load
✓ Transparent sampling procedure – Total
impartiality
✓ Cost savings from biomass
✓ Fuel receiving open 24/7
✓ Q-Robot can handle several types of solid
biomass
✓ Fast sampling sequence
✓ Automated sampling and sample handling
brings cost savings from labor
✓ High quality products made in Finland
QUALITY CONTROL CURRENTLY
• Manually from the top of the
load or during/after unloading
• Hard to get representative
samples from each load.
SAMPLING QUALITY INFORMATION INFORMATION UTILIZING• Error in caloric value because of manual
sampling (Energy balance error)
• Unreliable moisture information for the logistic
and process management or for the supply
chain
• Truck -specific moisture and
energy content information or
information from the combined
samples after 1-2 days
THE PROBLEM
The biggest problem in solid biofuel quality
management is sampling*
80%15% of error caused by sample handling
5% of error is caused by measurement
of error is caused
by wrongly taken samples

• Representative samples taken
automatically from each arriving
truck / wagon before unloading
Q-ROBOT• Automatically Pre-handled samples ready for laboratory
analysis
• Real-time calculated moisture information and volume
information available
• Integrated online moisture and particle size analyzer to Q-
Robot (future plan)
QUALITY INFORMATION• Payment based on actual delivered fuel energy content
• Logistical and combustion optimizing possible
• Calculated moisture information available in real-time for the
whole supply chain available
INFORMATION UTILIZING
Q-LINKTM concept
Q-ROBOT TM
✓ Fully automated sampling
✓ Q-Robot can form a tuck –specific or daily
sample automatically
✓ Patented solution
✓ Q-Robot can be placed where ever it is
logistically rational
✓ Representative samples from the each
arriving truck / wagon before unloading
✓ Sampling sequence under 10 minutes with 6
samples
✓ Sampling follows closely standards EN ISO
18135 and EN ISO 14780
✓ Q-Robot works with biomass, coal,
concentrate and any granular material which particle size in under 100mm
Q-ROBOTS IN OPERATION
✓ At Kuopion Energia power plant over 100 trucks per
day are being sampled (1600 GWh/a)
• Proven to bring a major cost savings
• Fuel energy balance error is ~0%
• All biomass trucks goes through the sampler
(Wood chips, forest residue, peat, saw dust and
peat)
✓ At Napapiirin energia ja Vesi power plant in Rovaniemi
about 40 trucks per day are being sampled (900
GWh/a)
• Reliability: Extreme conditions -25 degrees
Celsius
✓ At Fortum Joensuu power plant all trucks delivering
biomass are sampled daily 20 – 60 trucks (800
GWh/a)
• New innovations: sampling hall and operational
container
✓ 4th Q-Robot will be installed to Kajaani in April 2019
(800 GWh/a)
✓ 5th Q-Robot will be installed to Stockhom in
Commercial use
Ongoing project
RESULTS Q-ROBOTIn the chart below there is a comparison from 50 samples taken by Q-Robot and by truck
driver.
The moisture level in samples taken by Q-Robot is 3,5 percentage point higher compared
to samples taken by drivers. The differences are the biggest in wood chips. Samples have
been taken from Kuopion Energia Oy, Finland

RESULTS Q-ROBOTComparison study from 21 samples taken by Q-Robot and by Prometec employee.
The moisture level in samples taken by Q-Robot is 5,8 percentage point higher compared
to samples taken from the top of the load by Prometec. This study was made at Napapiirin
Energia ja Vesi power plant in January 2018. The site is located in Northern Finland.
