Masonry oven modular ovens, all these methods are still in use. In all cases, the ovens typically go under a roof or some kind of weather protection. Perhaps the most significant change in masonry oven construction practices is insulation. Since masonry loses heat as fast (or faster) than it absorbs it, early ovens extended bake times by increasing mass. Thicker walls held more heat to bake more bread — but only up to a point. Since heat moves from high to lower temp, the outside of the oven can’t get as hot as the inside — unless you wrap it in a
Ceramic heat cell Ceramic heat cell A ceramic heat cell, also known as Caloric Porous Structure Cell (CPSC), is a ceramic device to burn a fuel without flame, converting the thermal energy to mechanical work. In principle any fuel that can be vapourised and pre-mixed with air can be used. "Ultra vaporized steam" replaces the exploding air/fuel mixture as the work medium. The flameless combustion keeps emissions of hydrocarbons, carbon monoxide, and nitrous oxides extremely low. Exhaust gas can be recirculated, which further reduces emissions. A ceramic heat cell made by German firm Enginion is claimed to generate up to 30 megawatts of
