Abstract This paper introduces a radiant heat recovery heating system that the heat is obtained from a 2 500 t/d cement rotary kiln in Shandong Province. According to the load of heating system, the author calculated the amount of heat required from the surface of rotary kiln, and designed the heating device, heat storage and transportation system and control system of heating system. According to the actual operation of cement kiln for 300 days a year, 1 368 000kWh of heat can be obtained from the surface of rotary kiln, which is approximately equal to 168 000kg of standard coal. The system achieves the goal of energy saving, emission reduction and comprehensive utilization of resources.
