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 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 article presents results of research on drying a
slurry consisting of distilled water and finely chopped
cooked chicken protein of table eggs. The suspension
is placed in a Memmert oven, which has temperature
of 60 °C. In the process of removing moisture when
drying the slurry of water - boiled protein we
examined kinetics of its drying and performed
chronological photographing of conformation of the
system of water - boiled protein. The final weight of
the protein remaining after evaporation, was 0.06 g
corresponding to 26% by weight of cooked protein
source in an amount of 0.23 g. The analysis of the
system appearance including the evaporation of the
water showed that the protein was originally white,
and this color does not undergo any changes until 35
minutes of drying, i.e. when the main base is water.
Upon further drying of the suspension, starting with 40
minutes, boiled protein literally "melts" in the
surrounding water residues; and as it is disappearing,
becoming more and more transparent. Meanwhile, the
forms of the protein are becoming round and
transforming into the form of liquid crystals. The final
phase of the protein is a solid transparent film
The article gives a review and the experimental data on
the nutritional value of eggs protein comprising
protein, carbohydrates, minerals and amino acids.
Metabolism, the structure and function of each cell, as
well as external and internal protective functions are
defined by proteins. We consider the study of
functions of trace elements found in significant
numbers in the eggs, which contribute to health:
vitamin D, vitamin B12, choline, folic acid, selenium,
lutein and zeaxanthin. The high content of egg protein
contributes to greater satiety, weight loss and eye
health. We present experimental data on the amino
acid composition of the protein and experiments of
drying a cooked egg white, placed in a Petri dish.
After 10 minutes of drying, the weight of the protein
did not change and amounted to 0.1 g, which is 16% of
the weight of the original white protein. The photo
shows that the protein is lost during drying white and
became transparent, and protein grains look like
"melted" and partially connected with each other. The
data obtained can be used for understanding the
operation of the biological process of protein in vivo
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
We have performed an experimental study of the
evaporation process at a temperature of 105 ° C for the
egg white model solution in distilled water to evaluate
the ratio of the heat transfer coefficient from air to
water ratio mass transfer to the water surface into the
air by evaporation from the free surface in a forced
convection. Evaporation of the solution was carried
out in a Memmert oven of class Basic (Germany)
equipped with forced air circulation, the control panel
with a display and a temperature control device. To
determine the surface temperature at which the main
evaporation of water from the process solution, the
experiment conducted under the same conditions by
measuring the average temperature of the layer of
water sample, placed in a Petri dish in an oven with a
sensor - DMM Mastech M838 series. It is found that
the coefficient of heat transfer from air to water almost
a thousand times greater than the coefficient mass
transfer from the water surface into the air
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
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 article describes the sources of noise Yeisk
thermal power plant (TPP) in excess of the permissible
sound pressure levels in homes on the street. Gorky,
25. Eisk TPP is located near the residential area, where
the permissible noise level standards adopted much
more stringent than in the power plants. Prolonged
exposure to noise leads to human disease noise
disease. The scheme of movement of exhaust gases
from the thermal power plant generating units Yeisk.
Analysis of measurements of noise characteristics of
main and auxiliary equipment showed that one of the
main sources are sectioned estuaries double-barrel pipe
height of 27 m and slices estuaries pipes emergency
explosive valves flues installed on the roof at a height
of 17 m. The previous Noise reduction nozzles that
emit noise uniformly in all directions are replaced by
advanced, whose index changed direction estuaries
sections double-barrel tubes. This will change the level
of radiated noise in residential development. If you
change the angle of orientation of 135°-180°, the noise
level in residential construction decreased by 7-10 dB.
