How much biochar can a continuous carbonization furnace produce in a day?

Continuous carbonization furnaces have become one of the preferred equipment for many companies to produce biochar due to their high efficiency and energy saving. So, how much biochar can a continuous carbonization furnace produce in a day? This depends on many factors, such as the model of the furnace, the type of raw materials, operating conditions, etc.

1. Models and specifications of furnaces

Continuous carbonization furnaces can be divided into various models and specifications according to different production capacities and design structures. The production capacity of furnaces of different specifications varies greatly. Generally, the output of small continuous carbonization furnaces is between 500 kg and 1 ton/day, while the output of large continuous carbonization furnaces can reach 5 tons to 10 tons/day. The continuous carbonization furnaces produced by Hengju Machinery have a high level of automation, which can ensure the process of continuous feeding and continuous carbonization, greatly improving production efficiency.

2. The impact of raw material type on output

The production of biochar mainly depends on biomass raw materials, and the carbonization efficiency of different raw materials varies. For example, wood, straw, rice husks, coconut shells, etc. are all common biomass raw materials. Generally speaking, the carbonization rate of woody biomass raw materials is relatively high, reaching 30-40%, while the carbonization rate of non-woody raw materials such as straw and rice husks is relatively low, usually 25-30%.

Taking a continuous carbonization furnace with a production capacity of 5 tons/day as an example, if the raw material is wood (carbonization rate is 35%), 1.75 tons of biochar can be produced every day; if rice husks (carbonization rate is 25%) are used, the daily biochar production is 1.25 tons. Therefore, the choice of raw materials has a direct impact on the final biochar production.

3. Operating conditions and production efficiency

In addition to the specifications of the furnace and the type of raw materials, operating conditions are also an important factor affecting the biochar production. Temperature, residence time, oxygen supply, etc. will affect the efficiency of the carbonization process. The continuous carbonization furnace produced by Hengju Machinery usually operates under high temperature conditions of 400-600°C. Within this temperature range, biomass raw materials will quickly carbonize to produce biochar. An efficient temperature control system can ensure a constant carbonization temperature in the furnace, thereby maximizing the carbonization rate of the raw materials.

At the same time, the design features of the continuous carbonization furnace enable the material to enter the carbonization zone evenly and stably, which avoids excessive or incomplete carbonization of the material during the carbonization process, further improving the yield and quality of biochar. In addition, modern carbonization furnaces are also equipped with exhaust gas treatment systems, which can convert the gas generated during the carbonization process into usable energy, thereby improving energy utilization and reducing production costs.

In summary, the daily biochar production of a continuous carbonization furnace depends on many factors, such as the model of the furnace, the type of raw materials, operating conditions, etc. Normally, the daily output of a continuous carbonization furnace can range from 500 kg to 10 tons.
