Large eddy simulation LES has become a promising tool for pulverized coal combustion with the development of computational fluid dynamics CFD technologies in recent years. The coal-fired power plants in China are now required to be operated in a wide load range and quickly respond to the electric grid. The boiler performance of variable loads should be evaluated in terms of flow, heat transfer, and combustion processes.

The predicted gas velocities agree well with the thermal calculation and the temperature error is less than K. The simulation results show that the operation load has significant effects on the boiler performance. It is also proved that LES can provide guidance for the design and operation of advanced coal-fired boilers. This is a preview of subscription content, log in to check access.
