 The process of adjusting and controlling the temperature of the carbonization machine usually involves several key stages, and the temperature requirements and control methods of each stage are different. The following is a typical carbonization machine temperature adjustment and control process:

1. Drying stage: from ignition to the furnace temperature rising to about 160℃. This stage mainly relies on the heat generated by the external heat and the evaporation of the moisture contained in the raw materials themselves. The chemical composition of the machine-made sticks or logs will hardly change at this stage.

2. Initial stage of carbonization: The furnace temperature is between 160℃ and 280℃. This stage mainly relies on the combustion of the raw materials themselves to generate heat. The wood material begins to undergo thermal decomposition reaction, and its chemical composition begins to change.

3. Comprehensive carbonization stage: temperature range: 300℃ to 650℃. At this stage, the wood material undergoes rapid thermal decomposition, generating a large amount of liquid products such as acetic acid, methanol, wood tar, and combustible gases such as methane and ethylene. These combustible gases burn in the furnace, generating a large amount of heat, which further increases the furnace temperature.

4. High-temperature carbonization stage: temperature range: about 800℃ to 1000℃. If high-temperature charcoal needs to be burned, it is necessary to continue to increase the heat to make the temperature in the furnace continue to rise.

Temperature control technology and equipment include: temperature sensor, controller, heating equipment, fine-tuning mechanism. Use high-precision temperature sensors (such as PT1000 thermal resistor sensors) to monitor the temperature in the furnace in real time; use advanced controllers (such as STM32F103 microcontrollers) to accurately control the temperature; according to the type and specifications of the carbonization machine, select suitable heating equipment (such as thermal oil heaters, resistance heaters, etc.); adjust the fan angle and air volume, etc., to fine-tune the temperature in the tank to ensure the uniformity and stability of the temperature.

The temperature adjustment and control of the carbonization machine is a complex and delicate process that requires comprehensive consideration of raw materials, equipment, operation and safety. Through reasonable temperature control, the smooth progress of the carbonization process and the quality of the carbonized products can be ensured.
