“…In cavity heat exchange, the largest difficulty lies in evaluating what portion of the total heat flux emitted by the kth surface reaches the jth surface. In the reported technique, the surfaceto-surface (S2S) model [11] of radiative heat exchange is employed to solve the equations (2) for the radiative fluxes. In the S2S model, the heat flux exchanged between the jth and kth surfaces is evaluated based on their mutual orientation in space using the configuration factor F j,k .…”

“…Several papers dedicated to the developed modeling technique, its implementation and modeling results are currently under preparation. The first paper has been recently included in the program of one of the most prestigious forums in microwave technologies -the 2012 IEEE MTT-S IMS [11]. The paper was peer reviewed -it was accepted as a result of a scrutinizing evaluation of the 2012 MTT-S IMS Technical Review Program Committee.…”

that a production size MAT rotary calciner was not feasible, and a different approach was adapted. The concept of a microwave post heat section located in the upper portion of the cooler was devised and well received by the industrial lime company and an industry expert. Commercialization of this technology will require 1) continued pilot scale calcining demonstrations, 2) involvement of lime kiln companies, and 3) involvement of an industrial microwave equipment provider. Ceralink identified two builders of lime kilns whom could be approached to partner with for continued technology and equipment development. Eventually, Ceralink would plan to license and transfer the technology to the kiln builders once the technical aspects are finalized. The lime company could then implement the MAT post heating sections in new builds and pursue retrofit of existing lime kilns in order to improve efficiency. Retrofits would likely be attractive to lime manufacturers, as the purchase of a new lime kiln is on the order of a $30 million dollar investment, where as a MAT retrofit might be on the order of $1 million. Ceralink would receive a royalty from the kiln builder. Current scale-up designs indicate that four 100kW microwave generators (915 MHz frequency) will be required to provide sufficient energy to a chute measuring 6ft in diameter and 4 ft. long to finish calcining the limestone before the limestone is cooled. This is scale for a production size rotary calciner with 600 ton/day output. Ceralink has identified a microwave equipment supplier who could supply the required microwave equipment and engineering work to assist with design and integration.
