We have applied rapeseed oil to improve
the industrial fuels based
on waste-derived coal water slurry. This unifies the two modern trends
of creation of the renewable and waste-derived fuels decreasing the
consumption of combustible fossils. The fuel consisting of the filter
cake of fiery coal (90 wt %) and rapeseed oil shows an optimal
ignition delay times (∼4 s) at 970 K, which is evidently better
than that for coal water slurry doped by fuel oil. Simultaneously,
it shows a stable combustion temperature exceeding that observed for
composition with fuel oil. These results were compared with properties
of the biofuel consisting of the rapeseed oil (65–70 wt %)
and biofiller made from dry straw. This composition shows good combustion
properties at low temperatures. An optimal ignition delay (∼2
s) appears at T ≈ 825 K. The rapeseed oil
itself shows the high fire safety during storage and less of the harmful
exhaust gases than oil-processing wastes usually used within the waste-derived
fuels.
