The paper presents a technical solution for modernization with the aim of increasing the efficiency of the steam boiler of TPP Ugljevik, which implies the reorganization of the combustion system. More efficient operation of the furnace
can be achieved by replacing the existing burners, reducing the number of burner
levels as well as the organization of tangential combustion. The flame formed in
the shape of a tube around the two central combustion vortices provides a larger
amount of heat transferred to the combustion furnace, less fouling of its screen
walls and thus a lower average temperature of the combustion products at its
outlet. As the chosen reorganization affects the increase of the temperature of the
superheated steam and the decrease of the temperature of the reheated steam, it
has been proposed to reduce the area of the semi-irradiated superheater and increase the area of the second reheater. Taking into consideration that the reorganization of the combustion syste...m may lead to the change of the thermal load
of the evaporator located in the furnace, the paper presents the work of the steam
boiler operation under new operating conditions. Used calculation system enables reliable prediction of operating characteristics of the steam boiler in new
operating conditions of combustion, and its application helps assess the quality
of the boiler in terms of how effective, efficient, safe and environmentally friendly
its operating mode is. In this way, it is possible to form a comprehensive description of the operating mode of the steam boiler.
