When combustion of fuel in thermal power plants,
combustion products are formed, which contain: fly
ash, particles of unburnt pulverized fuel, sulfuric and
sulfur dioxide, nitrogen oxide, gaseous products of
incomplete combustion, sodium salts, soot particles,
calcium dioxide, etc. Getting into the atmosphere, they
cause great harm to the components of the biosphere.
The article presents a laboratory analysis of industrial
emissions into the atmosphere of 1-7 power units for
2015 and 2016 at Novocherkassk State District Power
Plant. The components NO2, NO, CO, SO2, C (soot)
have been determined. It is established that for the
whole observed period of excess of maximum
permissible emissions was not revealed. Emissions of
each of the components are within the same level and
are stable
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)
