What Are The Three Types Of Furnaces?

2025-08-18

Biomass charcoal is an important energy source. It has found widespread application. Selecting the appropriate carbonization furnace is a critical piece of equipment for producing high-quality biomass charcoal. Today, we will provide a detailed overview of the types of carbonization furnaces available.

 

Horizontal Carbonization Furnace

This furnace employs a dry distillation carbonization process. It offers advantages such as simple construction, low cost, and cost-effectiveness. Horizontal carbonization furnaces are primarily constructed from industrial-grade materials such as refractory bricks, steel plates, and steel. It is suitable for small-scale biomass carbonization production. The carbonization cycle takes 10–12 hours. It is commonly used for the carbonization of biomass raw materials such as coconut shells, logs, branches, tree trunks, wood charcoal sticks, etc. The generated gases can be filtered and dust-removed through a flue gas purification device. Combustible gases are transmitted through pipes to the bottom of the carbonization furnace for combustion, achieving the purpose of secondary heating and temperature increase.

Vertical Lifting Carbonization Furnace

It also employs the dry distillation carbonization process. The vertical lifting carbonization furnace features a mobile steel plate structure. Logs are heated and decomposed into combustible gases and solid charcoal under oxygen-deprived conditions. The exhaust pipes at the top of the furnace are connected to an exhaust fan. The crane-mounted carbonization furnace offers advantages such as rational structure, large effective volume, good environmental performance, and long service life. Environmental protection purification furnace: It can purify the tar and other flue gases generated during carbonization. This significantly reduces flue gas emissions into the air and prevents secondary pollution of the external environment.

Continuous Carbonization Furnace

It is a more advanced continuous carbonization device. The continuous carbonization furnace achieves continuous carbonization of biomass by rotating the furnace body. Not only does it have high carbonization efficiency and a significantly shortened production cycle, but it is also very suitable for large-scale production. The drum-type carbonization furnace also features high-temperature resistance, ensuring uniform quality and high efficiency of biomass charcoal.

Continuous Carbonization Furnace

When selecting a carbonization furnace, multiple factors must be considered comprehensively. First, the required production scale. Small-scale production is more suitable for simple carbonization furnaces. Large-scale production is recommended to choose continuous carbonization furnaces. Second, carbonization efficiency is also critical. High-efficiency carbonization furnaces can achieve high carbonization in a short time, improving production efficiency. Additionally, factors such as production output quality, equipment stability, durability, installation and commissioning, and after-sales service must be considered. All these are important factors to consider when selecting a carbonization furnace.

 

In summary, selecting the appropriate carbonization furnace is critical for biomass charcoal production. By thoroughly understanding the composition and characteristics of various carbonization furnaces and comprehensively evaluating them based on specific needs, the most suitable carbonization furnace can be selected. This not only enhances production efficiency and reduces production costs but also ensures the quality of biomass charcoal.
