Abstract

The mathematical modeling of the work of convection surfaces of boiler TPP 312 of Ladyzhinskaya TPP was carried out. The areas of high erosion for the main modes of boiler load are determined. The method of aerodynamics control in the volume of boiler firebox TPP-312 is proposed in order to reduce the erosion of heat exchange surfaces. While maintaining the capacity of the Ladyzhinskaya power plant at the current level during the remaining block life, the application of the control method will allow the resource of the convection surfaces of the block to be extended by 1 year.
