The continuous carbonization furnace China is a type of carbonization equipment that is both high-efficiency and energy-saving. This equipment can convert various types of wooden materials, such as wood sawdust or peanut shell, into charcoal. This apparatus is capable of carbonizing in a continuous fashion for a full day, allowing for simultaneous feeding and discharging. Carbon monoxide, methane, and hydrogen are some of the combustible gases that will be produced by the materials while they are going through the carbonization process. Following its journey through the flue gas purification system, the combustible gas may then be subjected to secondary combustion in order to achieve the desired effects of carbonization and heating in reciprocal cycles. Not only does the recycling of combustible gas save energy, but it also gets rid of the issue of pollution in the surrounding environment. The continuous carbonization furnace China is the piece of machinery that excels above all others when it comes to the manufacturing of large quantities of charcoal.
Arrangement of the components that make up the rotary charcoal carbonization furnace
The gasifier, the carbonization furnace, the flue gas purification device, the conveying device, and the other various pieces of equipment make up the bulk of the entire set of machinery.
In the beginning stages of the process, the carbonization furnace gets its initial heat from the gasification furnace
Following an initial phase of preheating, the material is fed into the carbonization furnace via the screw conveyor, where it immediately begins to undergo the carbonization process as a result of the rotation of the furnace body
During the carbonization process, the raw materials will give off a number of different types of flue gases that can be burned
After the flue gas has been recovered, it is sprayed, cooled, purified, and separated before being sent to the combustion chamber by the induced draft fan
This is done in order to maintain a constant temperature in the carbonization furnace
At this point, the heating of the gasifier can be gradually turned off, and at this point, only the flue gas generated during the carbonization process is used for heating
After the carbonization process is complete, the finished product is finally added to the silo after the discharging machine is cooled down
Charcoal carbonization using a rotary furnace and its operating principle
The drying stage, the beginning stage of carbonization, the full carbonization stage, and the cooling stage are the primary stages that make up the carbonization process that occurs in the carbonization furnace when materials are being carbonized.
The temperature inside the gasification furnace increases to a certain level as a result of the ignition and heating of the furnace during the drying stage of the process. At this point, the chemical composition of the material does not change very much, and the evaporation of the moisture that is already present in the material is primarily dependent on the heat that is generated by combustion that is taking place outside of the material.
The first stage of carbonization, which consists of:At this point, the majority of the heat necessary to generate heat and bring the temperature in the furnace up to the level necessary for carbonization comes from the combustion of the material itself. At this point, the material goes through a reaction known as thermal decomposition, and as a result, its chemical composition is altered. Some unstable components decompose slowly.
Full carbonization stage:At this point, the wood material goes through a phase in which it experiences a rapid thermal decomposition reaction. Simultaneously, a significant quantity of liquid products such as acetic acid, methanol, and wood tar are produced as a byproduct of this reaction. In addition, combustible gases such as methane and ethylene are produced, and the furnace is used to burn these combustible gases. The thermal decomposition reaction and the combustion of gas both produce a lot of heat, which causes the temperature in the furnace to rise. At this high temperature, the wood material is converted into charcoal through a process known as dry distillation.
Phase three is the cooling process. Once the material has been carbonized, it must be cooled before it can be stored; otherwise, it is flammable when exposed to air.
The components that make up the carbonization furnace for the charcoal
Sawdust, peanut husks, corn stalks, branches, rice husks, and other biomass-containing materials are typically processed in a continuous carbonization furnace, which is the primary application for this type of furnace.
The benefit of utilizing a carbonization furnace that operates continuously
The rotary carbonization furnace offers the benefit of a high degree of automation, which allows for the possibility of continuous operation for twenty-four hours a day.
The devices for the recovery of flue gas, incineration of flue gas, and removal of dust all work together to ensure that the flue gas complies with the emission standards.
Augers that use water or coils to cool the material ensure that it is cooled quickly and have the advantages of requiring less floor space and saving space overall in comparison to other equipment that performs the same function.
In order to save both time and effort, the entire collection of machinery utilizes a bucket elevator.
It is simple for some types of sawdust with small particle sizes to accumulate in the standard carbonization furnace, which leads to an insufficient amount of thermal carbonization being achieved. In addition, the rotary carbonization furnace that we use ensures that the carbonization process is carried out perfectly.
The carbonization is consistent and fast throughout the drum-type continuous carbonization furnace manufacturer thanks to its uniform heating and rapid heat transfer. It has a production efficiency that is 10–20 times greater than that of a carbonization furnace that is static, meaning it can carbonize 3–5 tons of materials per hour on average.
