Optimization of TSR in cement kilns can be achieved by using a high quality and consistent alternative fuel product. This case study indicates how a rigorous QC based approach to the production of solid alternative fuels in cement kilns was developed that contributes to maximum TSR. PEF differs from conventional solid alternative fuels in that production begins with the best material possible as the...
The prototype and a new design of modular biochar torrefaction system were devised here, as a spin-off from "2010 Project on the Promotion of Green Community in Chiayi County" in Taiwan. Results from the batch tests using the prototype confirmed that the ratio of biochar to fuel in terms of CO2eq is greater than 1.0 for densely-packed materials such as camper wood (Cinnamomum camphora (L...
Co-processing of various alternative fuels in cement kilns has become meanwhile more or less state-of-the art in many areas of the world. It has become more established and accepted by the industry as prices for primary fuels are steadily increasing. Another reason is the global goal to reduce greenhouse gas emissions (CO2). To successfully fulfill individual production targets, process related influences...
This paper presents operating experience from different calciner solutions operating with high degrees of substitution for alternative fuels. Experience with fuels having very different combustion characteristics is presented. Data are presented for different emissions including CO and NOx. Two calciner solutions are considered in particular detail. A calciner solution including a disc reactor particularly...
Aimed at the low quality of the product and low recovery rate of coke calcinations in rotary kiln, an intelligent optimization operations system for coke calcinations rotary kiln is presented to stabilize the temperature in calcination zone in this paper. The key operation parameters in rotary kiln are optimized using improved case-based reasoning (CBR). The case searching and matching adopted the...
The important task to update production process by means of latest technological developments must be accomplished by both the equipment supplier and the cement producer. The equipment supplier, being the technological partner to the industry can thus help greatly to stay competitive in the changing face of the industry. Off late due to the rapid growth rate of Indian economy there has been a thrust...
Proven strengths in the areas of environmental emissions, maintenance, alternative fuel utilization and energy efficiency have resulted in long term solutions that offer significant operating benefits. Technical expertise combined with multi-disciplined engineering and deep project resources, such as dedicated training and safety staff, result in the best total value for the cement producers
