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 content of metals in raw rice is determined.
Inversion voltammetry (IVA) was carried out in an
accredited laboratory on the "Ta-Lab" device of the
company "Tom-Analit" LLC according to the
approved method of ERD F 16.1: 2: 2.2: 2.3.46-06.
Silicon dioxide is determined according to ERD F
16.1: 2: 2.2: 3.65-10 and humidity according to GOST
5180-2015. Preparation for the IVA is illustrated.
Voltammograms of the potential difference of the
chloride-silver reference electrode are compared with
the current strength of the indicator mercury-film
electrode of electrochemical cells. It has been
established that the main metals of the raw rice called
Regul grown in the Krasnodar region are: copper 1.6 ±
0.4 mg/kg, plumbum 1.4 ± 0.4 mg/kg, zinc 1.9 ± 0.5
mg/kg, iron 95 mg/kg, manganese 5.2 ± 1.3 mg/kg and
silicon dioxide 6.5 mg/kg. The presence of iron is
associated with the wear of gravity. The content of
zinc, manganese and silicon dioxide corresponds to
this type of grain. The presence of copper and lead is
associated with the absorption of heavy metals from
the soil
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 electric method of gas dedusting is the most
effective, since it allows capturing solid particles with
a size from 0.01 µm to tens of microns. The efficiency
of dust and gas cleaning equipment of Novocherkassk
SDPP for cleaning flue gases from ash at power units
1-7 in the period from February 2015 to February 2017
is considered. The main equipment is electrostatic
precipitators. As a solid fuel, Donetsk culm is used. It
is established that the efficiency of waste gas
purification at power units 5-7 was about 99 %, while
at power units from the 1st to the 4th this value was
within 95-96 %. The data obtained correspond to the
design data, but it is recommended that the cleaning
devices be improved to improve their efficiency. The
most acceptable is a combined electrofilter-bag filter
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,
The power plant being investigated is Novocherkassk
State District Power Plant located in the settlement of
Donskoy, Rostov region. The power object is included
in the list of objects of the fuel and energy complex
subject to categorization and is defined as critically
important. The analyzed site is the "subsidiary farm",
which includes a chemical reagent warehouse and a
site for chemical water purification, where hazardous
substances are treated: sulfuric acid and technical
sodium hydroxide. The analysis of the main causes of
accidents at thermal power stations occurred during
processing, storage and transportation of hazardous
substances, and typical scenarios of possible accidents
at the chemical water treatment plant of thermal power
plants were considered
The object of the study was the sweet pomace of red
varieties of grapes grown in village Taman Temryuk
district of the Krasnodar region. By grinding in a
laboratory mill and drying in a drying oven at a
temperature of not above 60 ºC, a powder is obtained
from the mash. Its quantitative chemical analysis has
been carried out. The mobile forms of metals and the
total content of metals are determined. The content of
mercury, lead, arsenic does not exceed the permissible
levels of the maximum content of toxic elements in
flour confectionery products. The influence of powder
from grape pomace on the quality of the finished
product and on the properties of the pastry test was
studied, as the control sample was chosen the recipe
for the sugar cookies "Carrot". A part of the flour was
replaced with grape-dried powder in amounts of 1 %, 2
%, 5 % of the mass of wheat flour of the highest grade
in the test. The recipe of sugar cookies with the
addition of powder from grape pomace and without,
calculated on 200 g of finished product, and
organoleptic parameters of the finished biscuit is
given. It is established that the use of grape-dried
powder allows to increase the mass fraction of dry substances and to reduce the mass fraction of sugar in
confectionery products, as well as to enrich them with
mineral substances, microelements, which are
necessary for normal functioning of the organism.
Biscuits with the addition of powder from grape
pomace are a good source of ballast substances
reducing caloric content, which contributes to the
removal of harmful substances from the body:
cholesterol, heavy metal salts, etc
