Flow analysis of Eco Duct is my power plant process-case study using computational fluid dynamics. Economiser to APH duct is an important as well as critical duct segment in balanced draft system where the Flue has very high temperature and also very high content of fly ash.This segment of duct contains a baffle system (Deflector) and 4 no of Hoppers to collect the Fly Ash.2-5% of total fly ash is collected by the hoppers and transported to the pneumatic fly ash conveying system. In this case study Ansys Workbench and ICEM CFD are used for solid modelling and mesh generation and CFX and FLUENT are used for analysis. The following site measurements are used for boundary conditions...
- Total Mass Flow Rate = 1113 TPH
- Pressure At Eco Outlet = -31 mmwc
- Pressure At APH Inlet = -70 mmwc
- Temperature At Eco Inlet = 461 Deg C
- Density of Flue = .835 kg/m3
- Flue Gas Viscosity = .000022 kg/m-s

Animation of Particle Flow in 3D according velocity profiles
- Now keeping the Hopper Outlet Pressure = -195 mmwc
- The Other Boundary Conditions same as previous.
