Description
Overview
This second‑hand biochar kiln offers a cost‑effective, durable solution for turning biomass into valuable biochar. Designed for farmers, agri‑brokers, and sustainable practitioners, it delivers reliable performance and comes with a full service history.
Key Features
Robust Construction – Built from heavy‑gauge insulated steel or refractory brick-lined enclosure, retaining high temperatures (approx. 450–500 °C) for efficient pyrolysis edenbiochar.co.za+13biochar.info+13Ritlee+13.
Self‑sustaining Flare‑Cap Design – After ignition, the kiln maintains internal heat by burning off‑gases, reducing fuel input and simplifying use .
Suitable Capacity – Ideal for small to medium batches (200–300‑litre drums), perfect for on‑farm production without needing cranes .
Emission‑Friendly Operation – With an afterburner or flare cap, it dramatically cuts smoke and VOCs, aligning with modern environmental standards .
Benefits On‑Farm
-
Soil Health Enhancement – Produces biochar that improves cation exchange, water retention and supports microbial life ScienceDirect+3biochar.info+3Ritlee+3.
-
Carbon Sequestration Opportunity – Lock in carbon and access potential carbon markets. Larger models (e.g., 1000–3000 L) can produce units for sale or offset credits .
-
Waste Management & Value‑add – Convert pruning branches, crop residues or invasive plants into a product you can apply or sell .
Ease of Use & Maintenance
-
Simple assembly – Fits 55–200 L retort drums with clamp-on lids. Load, ignite, run until gas self‑sustains, then quench.
-
Portable – Can be moved around the farm or between sites, even split into panels (portable models) BKI+4BKI+4biochar.info+4.
-
Minimal parts – Few moving parts beyond drum, lid, afterburner, and simple thermocouples; durable and low‑maintenance.
