An activated carbon carbonization furnace<\/strong> is a high-temperature rotary furnace. It converts carbonized material into finished activated carbon. This is the core machine in physical activated carbon production.<\/p>\n\n\n

The furnace heats carbonized material to 880\u20131050\u00b0C. Steam is injected into the drum. The steam reacts with the carbon structure. This opens closed pores, creates micropores, and expands some into mesopores. The result is activated carbon with high iodine value and large surface area.<\/p>\n\n\n\n

Before this stage, raw biomass must pass through a continuous carbonization furnace. That pre-carbonization step removes moisture, tar, and volatile compounds at 500\u2013800\u00b0C. The output is carbonized material. This material then enters the activated carbon carbonization furnace to become finished product.<\/p>\n\n\n

Shuliy supplies two main types of activated carbon production furnaces: internal-heat rotary carbonization furnaces and external-heat gasification continuous carbonization furnaces. Each type matches different raw materials, product grades, and production budgets.<\/p>\n\n\n\n

Two Main Types of Activated Carbon Production Furnaces<\/h2>\n\n\n\n

Internal-Heat Carbonization Furnace<\/h3>\n\n\n\n

The internal-heat type is a direct-heating rotary carbonizer. Hot flue gas enters the rotating drum and contacts the material directly. Heat comes from external fuel combustion and from the combustion of volatile gases released during pyrolysis.<\/p>\n\n\n\n

This design offers high thermal efficiency. It is 30\u201340% more efficient than external-heat systems. However, flue gas directly contacts the material. This can increase ash content and cause oxidation losses if airflow is not controlled precisely.<\/p>\n\n\n

\n
\"Internal-Heat

External-Heat Gasification Continuous Carbonization Furnace<\/h3>\n\n\n\n

The external-heat type uses indirect heating. The combustion chamber sits outside the drum. Hot flue gas heats the drum wall. The material inside the drum never contacts the combustion gas. The system maintains an oxygen-free environment.<\/p>\n\n\n\n

Volatile gases released from the material are collected, purified, and burned in the external combustion chamber. This creates a self-sustaining heat source. External-heat systems produce lower-ash carbonized material with less burn loss. They are ideal for food-grade, pharmaceutical, and high-end adsorption activated carbon.<\/p>\n\n\n

Total power for one carbonization line: 64.8 kW<\/p>\n\n\n\n

A full activated carbon plant usually needs four carbonization lines, plus screening and packaging equipment. The total installed power for four lines with screening and packing reaches approximately 271.88 kW.<\/p>\n\n\n
