Multiple Char Reactions for Coal Combustion

Simulation of Multiple Char Reactions for Coal Combustion

In this tutorial, we provide guidelines for modeling and simulation of coal combustion or gasification with multiple char reactions. We use finite-rate/eddy-dissipation model in our simulations.

You will also learn how to do the following through this tutorial:

  • Solving multiple char reactions for coal combustion employing discrete phase model
  • Modeling reactions occurring during combustion by activating the finite-rate/eddy-dissipation model
  • Setting up the solver and solving the problem
  • Also, Post-process the resulting data
  • Adding the radiation model and investigate its effect on the reaction temperature.

Problem Description of Coal Combustion

We consider a simple 10 m *1 m 2D duct as a coal combustion system. In our simulation, we only need to model half of the domain width due to the symmetry. Also, we have two inlet streams. The first one is a high-speed stream near the center of the duct with the velocity of 50 m/s and span of 0.125 m. The other stream enters at 15 m/s and spans 0.375 m. The temperature of both streams is 1500K. The mass flow rate of coal particles is 0.1 kg/s. Coal particles enter the combustor near the center of the high-speed stream. The temperature of the wall is 1200K. Based on the inlet dimension and the average inlet velocity, the Reynolds number is approximately 100,000. Therefore, the flow is turbulent.
