Makarov V. The promotion of improvement of the work of draught equipment of aggregate's boilers basis on a new criteria of design

The dissertation is devoted to solving one of the problems of heat complex of Ukraine, i.e. the limitation of thermal power boilers because of the lack of productivity of draft machines. Based on the new projection figures of forced-draft system, the expedience by improving the geometry of the flow parts. To improve the knee 90° and the inlet pipe of the flowing back fan, the mathematical method of determining the profile inserts was developed. In the course of the research, the experimental substantiation for the improvement of aerodynamic fans testing methodology was given, as well as the optimization of the methods of determination of the parameters of the forced-draft system.
