Example savings are summarized in Table 1. Another potential application of the technology is to de-water nuclear plant waste. OHT has successfully demonstrated the feasibility of using microwave energy to de-water sludge contained in 3 m waste storage flasks at Bruce Nuclear Generating Station B. Test results are summarized in Table 2. No No Carbon reactivation is another application for Microwave Technology. High temperatures are used to regenerate carbon by driving out organic compounds and expanding the carbon pores.
Typical regeneration is carried out in kilns using electricity, natural gas or other fuel.
Microwave heating reduces not only energy consumption but also carbon losses due to breakage. Figure 2 gives operating cost comparisons. Microwaves are used to regenerate carbon so that it can be re-used in the refining process. This method reduces refining costs, and consumes less energy than conventional recovery methods. Operating cost comparison of conventional vs. microwave kilns for carbon re-activation.
