To build a biomass steam generator using coco shells, it's essential to clarify whether the goal is simply to produce steam or to generate electricity. For basic steam production, burning coco shells to heat water in a pot is sufficient. However, generating electricity requires a more complex setup with pressure-resistant materials to handle steam pressure. Recycling water in the process can enhance efficiency and sustainability. Searching for designs of used wood-fired steam generators can provide a useful reference for adapting to coco shells.
