Energy efficiency calculations and an economical analysis has been conducted on two different carbon regeneration kiln types. The purpose was do determine what economical winnings there could be by replacing the carbon regeneration system using propane burner with one heated by electricity. This project was conducted on a carbon regeneration kiln that stands at the G1A processing plant in Boliden. The two different heating solutions were implemented in the multiphysics software Comsol to determine their energy efficiency’s, and then an economical analysis was conducted by comparing the annual consumption of energy per kiln type. The models were built to be as accurate as possible, but some simplifications had to be made to make the simulations possible. The results from the study showed that the electrical heating solution was over four times more energy efficient, which would lead to an annual saving of 745 714 SEK/year. The results of this simulation must however be considered somewhat inconclusive due to implementation difficulties, but it might serve as a good predictor as to why electrical heating panels could be economically feasible.
