Kravchenko O. Improving the productivity of draft-blowing ducts of boilers based on the improvement of the models of the aerodynamic systems.

The dissertation work contains previously unprotected scientific positions, which consist in the development of models and methods for presenting the parameters of aerodynamic systems to increase the productivity of the traction ducts of boilers. Replacing superchargers with more powerful ones increases the supply, but the power consumption for the operation of superchargers increases disproportionately. In the dissertation work the contradictions between the need to increase the productivity of the boiler ducts with the providing of energy saving requirements in the operation of aerodynamic systems are identified and analyzed. A model of energy representation in the form of two components is created: potential P and dynamics D, which allows to formulate energy saving problems with improving the representation of energy parameters of aerodynamic systems. Improving the geometry of the flowing ducts of the electrostatic precipitators of 300 MW power units in Kryvyi Rih provides an increase in the efficiency of dynamic processes. System analysis of changes in the parameters of the tract allows you to correctly justify the improvement of energy performance of the aerodynamic system as well as individual elements - the input sections of electrostatic precipitators.
