THERMAL IMAGING MONITORING OF BURNING AND FIRES STARTING 24

ON DEPOTS AND IN WASTE INCINERATION PLANTS

The amount of waste produced worldwide is continuously increasing. The Czech Republic produces annually ap-
proximately 3.5 to 5.5 million tons of communal waste. At present approximately 75% of communal waste in the
Czech Republic is stored on depots. About 400,000 tons of this waste is consequently thermally processed in waste
incineration plants in Prague, Brno and Liberec which produces about 2.3 million gigajoules of heat and about
18,000 megawatt hours gross production of electricity. For various types of waste products, thermal proceeding is
practically the only suitable way of processing.

TASK SPECIFICATION
ZEVO Malešice combusts waste for conversion to thermal and electric energy. This energy is used for heating
utility water and for heating residential houses. Waste fires when combusting waste is a real threat and this also
applies to ZEVO Malešice. The most frequent reason for fire when combusting waste is spontaneous ignition
during a reaction of chemical molecules and hot particles produced by vehicles transporting communal waste.
A factor that increases the probability of self-ignition is the high concentration of methane which is released

from the waste. To decrease the risk of fire, ZEVO Malešice decided to invest in a waste monitoring system from
Workswell. The main objective of the system is to monitor waste placement and eliminate any threatening fires.

SOLUTION

To solve this application, the SAFE-
TIS thermal imaging cameras sys-
tem was used with special software
primarily for monitoring the envi-
ronment to detect any burning, ig-
nition and significant temperature
increases. Up to 16 SAFETIS cam-
eras can be connected at the same
time which can monitor wide areas.
The stored waste in ZEVO Malešice
can be monitored continuously
24/7, i.e. all the time the workplace
is operating. For this specific ap-
plication Worskwell delivered two
