Drying stage from the start of ignition to the furnace temperature up to 160 °C, when the moisture contained rod mechanisms rely mainly on external heat and the heat generated by the combustion itself is evaporated. The chemical composition of rod mechanism hardly changed.
The initial stage of carbonization this phase depends mainly on the rod’s own combustion heat, the furnace temperature to rise to between 160 ~ 280 °C. In this case, a thermal decomposition reaction wood, the composition began to change. The composition is unstable, such as hemicelluloses decomposition of CO2, CO, and a small amount of acetic acid and other substances.
This phase full carbonization temperature is 300 ~ 650 °C. In this stage, the wood material is thermally decomposed rapidly, while generating a large number of acetic acid, methanol and wood tar and other liquid products. Methane, ethylene and other flammable gases, the combustion of combustible gas are also produced in the furnace. Thermal decomposition and combustion gases generated a lot of heat, the furnace temperature rises, and carbonized wood into carbon at high temperatures.
We design carbonization furnace by our own innovative ideas, innovate carbonization furnace, improve design process, greatly improved the production capacity, thus provide cost-effective carbonization furnace and professional technical guide to our customers. The carbonization furnace have been exported to Russia, Uzbekistan, Myanmar, Vietnam, Laos, Kazakhstan and many African countries.
