Abstract The research method of computational fluid dynamics (CFD) is used to study the technology of burning sludge in cement precalciner. The simulation results show that the flow field in the TTF precalciner is stable, the spray effect is good, and no raw meal collapse occurs. The special structure of the TTF (Trinal-sprayed) precalciner allows the pulverized coal and sludge to fully exchange heat with the flue gas and burn. When there is no sludge burning in the furnace, the decomposition rate can reach 92.1%, and the maximum temperature of the precalciner can reach 1600 K.… More >
