“…As of today, a large number of various devices with high efficiency of dedusting the gas flows were developed, for example, various modifications of inertial dust collectors, such as dust-collecting chambers, cyclones, etc. [9][10][11][12][13][14][15][16][17][18]. Easy operation, high reliability and ability to operate at high temperatures and pressures are important advantages of these devices.…”

The article deals with the problem of increasing the efficiency of dedusting the gas flow from the finely dispersed particles smaller than 10 μm. In order to solve this problem, a design of centrifugal separator with coaxially arranged pipes is proposed. The described principle of operation includes the large values of centrifugal forces, which take place inside the device when the flow is swirled, and these forces throw the finely dispersed particles to the walls of device. This scientific paper shows a numerical simulation of gas flow dedusting process by means of ANSYS Fluent software package. The efficiency of dedusting the gas from the finely dispersed particles of up to 10 μm in the device is on average within the range of 53.8–76.7%. The exponential function, describing the changes in the pressure loss from the input gas rate, is obtained. In the course of studies, it was found that the pressure loss in the device is not more than 800 Pa at the input gas rate from 3 to 19 m/s.

Highways are one of the main elements of the infrastructure and economy of any state. It is well known that the state and level of development of the country's highways directly affect the main economic indicators – the gross national product, the price level, budget revenues, the level of employment, and others. When developing multicomponent binders, as a rule, a systematic approach is used. New binders are considered complex systems consisting of subsystems or elements, each performing its functions. The elements in the system are not isolated from each other but grouped in such a way as to ensure the practicality of the entire system. It should be noted that any changes in a single element or replacing one element with another usually lead to a change in the properties of the entire system. The elements of the system are interconnected, and the more versatile the connections, the more effective the system is. The researcher's task is to correctly select the elements of the system, considering their properties and contribution to the system's overall structure. Of all types of metallurgical slags, blast furnace slags are the most widely used in the production of building materials due to their leading position in the overall balance, their ability to acquire hydraulic properties during rapid cooling, and others.
