Physical Resources To the west of the park, a ridge of limestone rises above the coast line, ultimately intersecting the shore northwest of the Park to form the cliffs called Silver Bluff. Except for a large contribution from precipitation, most of the natural freshwater entering the Park originat ed in the Everglades to the west of the ridge.

The TE fate depends on complex and multifactorial processes for all technologies based on thermal conversion (e.g., incineration, pyro-gasification, and pyrolysis) (Edgar et al., 2021). Oxide-forming elements and refractory compounds are often found in ashes and tars. Capture of volatile Cd and As chemicals depends on the filter quality.

A thermal energy storage (TES) system was designed based on a packed bed of rocks as storing material and air as heat transfer fluid. A pilot-scale 6.5 MWhth TES unit was built and tested. A dynamic numerical heat transfer and fluid flow model was developed and experimentally validated with measurements obtained from the pilot-scale TES unit.
