Does anyone have any experience with electric calciners in the 24" diameter range vs gas fired? The problem with gas fired is that there are so many controls, balancing valves and burner parts, something is always not working or out of tune. It seems to me that an electric calciner has "one dial" to turn temperature up or down and greatly simplifies control. I would expect far fewer maintenance issues and significantly greater control with electric. I realize the heating elements go bad and the connections tend to wear out, but that could be managed by overhauling the calciner every few years. The other thing that people make a big deal about is fuel cost. My understanding is that gas is 35-40% efficient and electric about 70% efficient. For a 24" calciner, that works out to about ~$40k/year more for electric. Not really a big deal in the scheme of things, and can be far outweighed by costs of downtime, maintenance and product quality associated with gas.
