Wood logs are a valuable biomass resource for charcoal production, but direct combustion can result in the loss of much of their carbon content and energy value. A horizontal carbonization furnace provides a dedicated solution for converting logs and other long-rod biomass materials into charcoal through controlled thermal carbonization. Horizontal furnace designs are commonly used for logs, hardwood, branches, bamboo and similar materials that are difficult to process in equipment designed for fine biomass particles.

The horizontal carbonization furnace is designed around the characteristics of large and elongated biomass materials. Logs can be loaded into the furnace and carbonized under oxygen-limited conditions. The process generally includes feeding and sealing, preheating and drying, anaerobic carbonization, cooling and charcoal discharge. This allows the original wood material to be gradually transformed into carbon-rich charcoal.

During carbonization, combustible gases generated from the biomass can be collected and reused as a heat source. This heat-recycling approach helps reduce the demand for external fuel after the initial heating stage and improves overall energy utilization. Dingli's horizontal carbonization furnace is specifically designed with a combustible-gas return combustion system for this purpose.

With its horizontal structure, controlled carbonization process and combustible-gas utilization system, the horizontal wood carbonization furnace offers a practical solution for turning logs and forestry biomass into valuable charcoal while making better use of available biomass resources.
