Clinker rotary kiln heat recovery

Jun 01, 2010 In the rotary kilns, the balance in the surface temperature is an important parameter for the clinker quality. For this reason, the temperature required should be maintained and heat loss in the rotary kiln should be kept steady. As a result of these findings, a heat recovery exchanger has been modeled in order to make use of the energy
