The volume of investment in renewable energy sources, in particular solar energy, is increasing
and occupying one of the leading positions in the scale of its use. Globally, the depletion of
traditional fuel resources will necessitate the introduction of solar energy installations.
In particular, due to the use of solar energy-based devices in hot water supply systems, it is
possible to save up to 60% of primary energy resources consumed in this system, and due to the
use of solar devices with high efficiency in the system, this indicator can be further increased.
In this regard, the use of systems based on high-efficiency solar energy installations, from an
energy and environmental point of view, is of political importance in the world, and their use to
solve the problems of eliminating climate change is of relevant and necessary importance.
Research activities aimed at increasing the use and efficiency of collectors of flat solar water
heaters in world renewable energy sources in hot water supply systems are being carried out.

Today, new methods to increase the efficiency of thermal energy generation are widely used by
thermal power structures.
The tasks of using metals, heat, natural resources (coal, oil, natural gas), that is, economical and
rational combustion of fuel, energy saving from them, protecting the environment, extending
the life of thermal power facilities, are the tasks facing energy technology professionals.
The inner walls of boilers, steam boilers and heat exchanger pipes are exposed to salts in the
water used over time. The appearance of smudges can be prevented by cleaning the water
entering the heat exchangers in several ways. Slime formed in heat exchangers is extracted by
hydromechanical, hydrodynamic, hydrochemical, electrohydropules and ultrasonic methods.
Several methods are used to clean the equipment. However, viewed from this perspective, the
invention and development of an environmentally friendly, cost-effective, highly efficient
method that does not affect metal is one of the top priorities.
In agriculture, any technological process takes place through the use of thermal energy, most of
which is produced by steam and hot water boilers.
The decentralized location of agricultural facilities over the entire farm area does not allow the
accumulation of steam and hot water production in powerful boilers, where it is recommended
to use chemical treatment of water to prevent scale-up. In agriculture, mainly low-capacity
boilers are used for steam output up to 1 t/h and a capacity of 1.15 m3. The use of chemical
water treatment is not economically viable, since the cost of the equipment exceeds the cost of
the boiler, in addition, additional on-duty personnel - highly qualified laboratory assistants are
required. As a result, in the boiler rooms of agricultural enterprises the water is practically not
cleaned, which leads to the formation of scraps on the heating surfaces of boilers.
Due to the fact that the dash has a weak thermal conductivity, overheating of the metal of heat-
conducting surfaces occurs, and if its thickness is large, the water circulation is disturbed, the
metal burns out, and the service life of the boiler is reduced. In addition, fuel combustion
increases. A multitude of estimates indicate that every millimeter of emissions leads to fuel
overconsumption by up to 2% or more.
Currently, there are many methods and devices for cleaning boilers. But the most common, and
in some cases irreplaceable, is the dissolution of sediments formed on heat-conducting surfaces
with the help of special devices with various reagents. Specialized devices known for cleaning
boilers are of sizes that do not allow them to be brought into the boiler room, which can cause
the equipment to defrost when used during the fall-winter period. For these reasons and because
of their high cost, they are not widely used in agricultural enterprises. In addition, there are
currently no engineering calculation methods available, and installations for this are not
commercially produced. Further, there are no science-based recommendations on optimal
cleaning regimes. Therefore, it is necessary to establish a justification of modes and design
parameters of the small-sized installation to enhance the process of decarbonization of boilers,
to make them downtime.
Various methods and means are known to clean and protect heat exchangers from the blast. All
methods are divided into two types: disassembled and disassembled. The method of cleaning
the heat exchanger is selected individually in each individual case, taking into account its
degree of contamination, design, properties and content of substances constituting the surface.
Development and implementation of energy-saving technologies is necessary to improve the
non-reagent methods to reduce the rate of rock formation in heat exchangers. The high costs of
cleaning and repair of equipment at oil refineries also determines the relevance of the chosen
topic.

Thermal exchanger protection and cleaning methods consist of ultrasound, electromagnetic, etc.
All of them contribute to the crystallization of solid salts in the water column and do not allow
the crystals to reach the size required for sediment formation.
The ultrasonic method differs in that it affects the formation and subsidence of the blast in
several ways at once. First, water by means of ultrasound helps the crystals of solid salt formed
by ultrasonically heated water are destroyed and separated. A dash is formed in a solid when a
solid div comes into contact with a liquid. Under the influence of ultrasound, calcium
carbonate crystals in water, their average size decreases to about 10 to 1 micron, increasing
their number and total surface area. With the action of ultrasound in water, the number of
crystallization centers increases dramatically (approx. 1000 times). This leads to the formation
of debris on the surface of the water column due to heat exchange.
Secondly, ultrasound can propagate over the surface and prevent rashes from forming on it.
And if there is already a layer of dash on the surface of heat exchange, ultrasound removes it,
which is performed in combination with cleaning and breaking off the dash fragments.
With a significant thickness of the previously formed dash layer, there is a risk of clogging of
the canals. Therefore, one of the main requirements for the successful use of the ultrasonic
technology is the pre-cleaning of the old layer of rock deposits.
Structurally, the ultrasonic setup is a pulse generator loaded with two magnetic transducers. The
transducers are attached to the outer surfaces of the heat exchanger at certain points by electric
welding and the generator is powered from 220 V mains.
The electromagnetic method shows that the mechanism of action of the magnetic field on
water and its compounds is not fully determined and is explained by polar phenomena and
deformation of salt ions. During processing, the hydration of ions decreases, ions converge on
each other and form a crystalline form of salt.
One theory is based on the effect of the magnetic field on colloidal mixtures of water, according
to the other, the structure of water changes.
When a magnetic field is applied, crystallization centers are formed, due to the release of solid
salts that are insoluble in a water volume. Thus, instead of solid mash, a finely dispersed clay is
observed that is migrating in water, which is easily removed from the surface.
It has been produced at the present time, devices of permanent magnetic and electromagnetic
types. The terms of use of magnetic water purifier devices are:
1.
water heating should be carried out at a temperature not higher than 95 ° C;
2.
carbonate hardness - not higher than 9 mEq/l;
3.
The content of dissolved oxygen does not exceed 3 mg / l, and the sum of chlorides and
sulfates - not more than 50 mg / l.
