Abstract:



Purpose.
Improving the energy efficiency of heat generation processes in vortex combustion systems of uncertified fuel by streamlining the dosing regimes of fuel mixture components using an automated control system.


Methodology.
The research process is based on mathematical modeling of the vortex combustion control system of uncertified fuel. A peculiarity of the study is the three-circuit interconnected proportional-integral-differential (PID) control of fuel and air dispensers taking into account their humidity and ambient temperature, as well as the implementation of correction of performance control devices (dispensers) on the basis of these data.


Findings.
To determine the rational dosing regimes of the fuel mixture components, experimental studies on energy-efficient heat generation processes in vortex combustion systems of uncertified fuel are carried out. The research results will be used in the process of setting up a technology management system based on fuzzy logic. For the first time, a comprehensive simulation model of the thermal energy generation system with an integrated control system is developed, which allows investigating the parameters of the heat generator by using different types of crushed fuel, as well as testing the system in normal and critical modes. This confirms the need to use artificial intelligence to optimize energy-efficient heat generation processes in vortex combustion systems of uncertified fuel.


Originality.
Based on the analysis of the characteristics of humidity, physicochemical and particle size distribution of uncertified solid fuel, temperature and humidity, as well as the percentage of oxygen in the flue gases, the effectiveness of rational dosing of combustion components is substantiated using controlled modes of fuel supply dispensers and pressure blowers to provide the required amount of air in the process of vortex combustion, which can be achieved through the use of intelligent control system.


Practical value.
The application of the declared developments will allow solving the economic, energy, ecological and social problems in Ukraine to a large extent at the same time, namely: 1) reduction in natural gas consumption; 2) new jobs; 3) reduction in harmful emissions into the atmosphere. As a result of the study, an automated heat generation system based on vortex combustion of uncertified fuel is developed. There are no analogues of such development, as the main fuel used in the drying process is elevator waste, grain cleaning waste and biofuels, shredded waste.
