Gas fired Masonry or Mud oven - retained heat?
This may be completely ludicrous, just playing scenarios. It mostly applies to commercial needs as on a small home scale, I know, wood isn't as prohibitive.
The availability of wood is not constant - some places access is easier or less expensive than others. Additionally, though I hate to use it, it's arguable anymore which harms the environment and resources more - the use of wood to burn, or using some sort of a "flame engine," don't know what you call it, but something that fires from a nozzle live flame in huge amounts (technical description; awesome, I know), used not to direct fire a bake but to do the same thing wood firing does, heat the masonry or mud to get to the proper retained heat for bakes.
Some sort of jet firing apparatus to heat the oven surfaces, not to direct fire the chamber itself during a bake. Is there such a thing done? Is it a viable (efficient, cost-beneficial) as a small commercial bakery brick oven alternative?
