Abstract

ABSTRACT: A numerical simulation coupled with the user-defined function (UDF) is conducted on a cyclone-fired boiler. The thermal boundary condition is established for the cyclone barrel. The effects of the temperature of critical viscosity and the refractory material thickness on slag behavior are investigated. The results show that the temperature of critical viscosity is closely related to the location where the slag begins to form in the cyclone barrel. The refractory material thickness remarkably influences the surface temperature of the refractory material, and the solid slag thickness adapts to the variation of the refractory material thickness.
