GLACIER is intended for modeling three dimensional reacting and non-reacting two-phase flow of gases and particles or droplets in complex geometries. Typical applications include coal-fired utility boilers, metallurgical processing furnaces, rotary kilns, and decoking process heaters. Particular emphasis is placed on combustion and gasification of pulverized coal and on pollutant formation and destruction.

- Multiple reaction rate processes for liquid vaporization, coal devolatization and heterogeneous particle reactions
- Steady state, laminar or turbulent flows
- Mixing and reaction of multiple fuels
- Full coupling between turbulent fluid mechanics, radiative and convective heat transfer, and chemical reactions
- Radiative heat transfer for scattering-absorbing-emitting, turbulent, sooting media
- NOx/SOx formation and destruction
- Variable thermal boundary conditions including adiabatic, thermal resistance, “heat exchanger”
- Prediction of particle trajectories, concentrations and dispersion
