Optimisation of combustion process in furnace of coal-fired boiler PK-38 using Computational Fluid Dynamics

Abstract

In 2016 and 2017, AO Machine Building Factory of Podolsk jointly with OOO ZiO-COTES realised the projects for the retrofit of boilers PK-38 Nos.3A, 4B at the Nazarovo GRES power plant. A range of implemented technical solutions [1] allowed reach stable continuous operation of boiler PK-38 at the Nazarovo GRES at loads as high as 270 t/h and significantly reduced nitrogen oxide emissions. Development of the burners system and combustion modes, as well as estimation of nitrogen oxides emissions has been performed using three-dimensional computational fluid dynamics modelling.

Selected Aspects of Combustion Optimization of Coal in Power Plants

“…Emissions of dusts and fumes return to levels accepted by modern energy law, so that power plants are not obliged to pay fines for too high harmful emissions [38,39]. The design and modernization principles provide for maintaining the original dimensions of the device, making intervention in the building structure of the power plant unnecessary [33,40].…”
