Abstract: The heat transfer mechanism between cement clinker and air in a grate cooler was studied, and based on the actual operating parameters of a 5 000t/d cement clinker production line in China, the heat transfer process inside the grate cooler was numerically simulated using porous media theory. A physical and mathematical model of the grate cooler was established, and the temperature field, pressure distribution, and flow field distribution inside the grate cooler were numerically simulated using Fluent fluid calculation software. The relationship between the temperature of the middle air intake of the grate cooler and the thickness of the clinker layer was analyzed in detail. Based on the simulation analysis results, the positions of each air intake of the grate cooler and the distribution of air volume were reasonably arranged.

Key words: grate cooler air intake numerical simulation waste heat power generation energy conservation and emission reduction
