CFD based investigations into optimization of coal pulveriser
In coal-fired power plant, pulveriser is the first major component, whose performance dictates the total power plant efficiency. Uniform flow rate and desired size fraction at outlet pipes along with higher classifier efficiency are three important The energy efficiency of a typical thermal power plant is about 35-40%. Thermal power plants have pulverized coal-fired boilers. The pulverizer is one of the Industrial Coal Pulverizer Model Simulation and Parametric

Numerical investigation of 660 MW pulverized coal-fired
The excellent performance of oxy-coal combustion power plant has been observed in term of its ability to capture carbon dioxide with 95 % purity and 96 % recovery rate. . The additional installations such as ASU and CPU units require higher auxiliary power, hence the net efficiency of the oxy-coal combustion power plant has been Unequal coal flow translates into unequal air-to-fuel ratio in the burner, deviating from the design value and thus increasing unburned carbon in fly ash, NO x and CO. Coarser particles at the mill outlet originate from poor separation and decrease the unit efficiency. In addition, coarser particles reduce burner stability at low load.CFD modeling of MPS coal mill with moisture evaporation
