Abstract
The composite quasi-liquid fuels made of different industrial waste become more and more attractive for scientists during last years. Coal-water slurry is one of the popular types of such compositions. Addition of the waste petrochemicals into the slurry allows decrease of the ignition delays of such composite for up to 27%. However, it has a non-trivial effect onto the atomization dynamics of the slurry making the size and velocity distributions of the aerosol more stable during propagation of the aerosol cloud. This, in turn, leads to more predictable ignition and combustion of the aerosol.
Highlights
The modern strategy accepted in the most of industrial countries is switching to the green energy when production of the wastes per arbitrary unit of produced energy have to go down
The effect of the addition of waste petrochemicals to the coal-water slurry has two branches:. It introduce much more uniform size and velocity distribution of fuel aerosol during the first meter of its propagation when main changes of parameters of aerosol occurs
The used nozzle produces in average 0.5 mm droplets that keep size very stable; petrochemicals allows up to 27% faster ignition of the CWSP aerosol particles relatively to coal-water slurry (CWS)
Summary
The modern strategy accepted in the most of industrial countries is switching to the green energy when production of the wastes per arbitrary unit of produced energy have to go down. This way requires the essential changes in technological chains and the first of all is a more effective usage of basic resources. An application of different combustible wastes as components of the composite fuels is a very attractive way to satisfaction of the increasing appetites of modern energetics [1,2] It allows solving both global problems of waste utilization and primary energy production simultaneously. Mixing of the different types of waste allows an effective synthesis of the properties of composition due to the combination of strong features of components with compensation of the weak points
