Changes in slag mobility can affect the position and shape of the fluid and cohesive zones. A high viscosity slag around the tuyeres leads to serious gas flow problems. Slag viscosity is a complex function of slag composition, temperature and partial pressure of O2. Also unburnt char, coke, and unburnt ash from the coal can interact with the slag.
