After silage of ash captured by the electrostatic
precipitator, we installed the cyclone of NIIOGAZ
CN-15-500 for exhaust gas pre-treatment of the ash
resulting from the process of burning solid fuels (coal
of Donetsk) in boilers of Novocherkassk hydro power
plant. The plant cyclone examination was performed in
a production environment of Novocherkassk hydro
power station comprising 4 cylindrical cyclone
element diameters of 500 mm, and is defined by its
real effectiveness, which amounted to 91%. After the
cyclone, the gas enters the two-bag filter FRKI-90KP3-2-2
designed to trap solid ash residues and installed
over the silo dry ash. Filters are manufactured in
climatic design for temperate and cold climate with the
accommodation category 4. The article shows the
characteristic of the test results and bag filters FRKI-
90K-P3-2-2 before and after the cyclone in the
cleaning system. The work presents the analysis of the
composition of the ash and compares it with published
data. It is experimentally proved that the inclusion of
Cyclone CN-15-500 in the process diverting gas
purification scheme allowed more efficient operation
of fabric filters, reducing the dust significantly for the
input gases
The flowsheet purification of exhaust gases in the
Novocherkassk SDPP after the electrostatic
precipitator on I-th stage of purification set group
cyclone, on the II-nd stage of purification - baghouse.
To determine the particle size distribution of fly ash,
we selected ash from the transport network to the
group cyclone, and the in a group cyclone, and in a
baghouse. With the help of the microscope "Biomed-
3" we produced pictures of ash particles with different
magnification. Granulometric composition of three
selected ash samples were determined according to the
mass content of particles of different grain size,
expressed in percent relative to the weight of dry ash
sample taken for analysis. For size fractions from 10
mm to 0.5 mm sieve method is applied without rinsing
with water, for size fractions less than 0.5 mm sieve
method is applied with water washing. The particle
size of the ash mixture, taken up before the cyclone,
Physical and chemical characteristics of the Stavropol
oil are provided. The found value of density of 853,6
kg/m3
is low and shows that oil mainly contains light
paraffin hydrocarbons. Distillation of test of oil is
carried out on the device of rectification of ARN-2 oil
to laboratories of the Tuapse oil refinery. On the basis
of experimental data, the curve of oil ITK is
constructed. The chromotographic analysis determined
a mass fraction of C1-C6 hydrocarbons in a model of
test of oil. The conclusion is drawn that according to
GOST 31378-2009 regulations the sample of oil can
be carried depending on a mass fraction of sulfur to the
2nd class ("sulphurous"); on density – to the 2nd type
("averages"); on content of chloride salts, waters,
mechanical impurity – to the 1st group; on a mass
fraction of hydrogen sulfide, marked - and
etilmerkaptan in the amount – to the 1st type. The
sample of oil is characterized by the low temperature
of hardening (minus 15 °C)
