Adjusting the carbonization depth is a key step in producing charcoal of different qualities, which is mainly achieved in the following ways:

1. Controlling the carbonization temperature

Low-temperature carbonization (300℃-400℃): produces low-quality charcoal with high volatile content, more smoke when burning, and low calorific value.

Medium-temperature carbonization (400℃-600℃): produces medium-quality charcoal with reduced volatiles, stable combustion, and moderate calorific value.

High-temperature carbonization (600℃-800℃): produces high-quality charcoal with very little volatiles, no smoke when burning, and high calorific value.

2. Adjusting the carbonization time

Short-time carbonization: incomplete carbonization, low-quality charcoal.

Long-term carbonization: sufficient carbonization, high-quality charcoal.

3. Controlling the oxygen supply

Anoxic environment: promotes carbonization, reduces combustion, and is suitable for producing high-quality charcoal.

Appropriate amount of oxygen: speeds up carbonization, but may reduce quality.

4. Selection and pretreatment of raw materials

Raw material types: Different raw materials have different carbonization characteristics, which affect the quality of charcoal.

Pretreatment: Pretreatment such as drying and crushing can improve carbonization efficiency and charcoal quality.

5. Equipment adjustment

Continuous carbonization machine: Control the carbonization depth by adjusting the feed rate, temperature and residence time.

Intermittent carbonization machine: Control the carbonization depth by adjusting the carbonization time and temperature of each batch.

By adjusting the carbonization temperature, time, oxygen supply, raw material selection and equipment parameters, the carbonization depth can be effectively controlled to produce charcoal of different qualities.
