What is Carbonization?
Carbonization is a thermo-chemical process. It allows transforming structured molecules of wood, and cellulose products into coal and carbon. Carbonization is obtained through the elimination of water and volatile substances from the vegetal matter, due to the action of heat in charcoal pile. It is a process for gaining renewable sources.
Biomass-An Inexhaustible Supply of Resource Repository
We all know green plants utilize chlorophyll to transform carbon dioxide and water into glucose by photosynthesis and store light energy in it. Then group glucose with starch, cellulose, hemicelluloses and lignin to form into the substance of plants. We can comprehend that so called biomass is the general name of all the organism generated by photosynthesis, including plants, crops, forest products, marine products(various seaweed) and municipal waste(paper, natural fibers) and so on. Therefore, biomass is the important renewable resource featured with huge amount and wide distribution.
Introduction of Biomass Carbonization Plant/ Agro Waste Carbonization Furnace
Biomass carbonization plant which is produced by Kingtiger GT is all equipped with high-efficient and energy-saving environmental-friendly equipment. This variety of environment machines is applicable to the carbonization of sawdust, rice husk and other small biomass and applies advanced technology to avoid bringing in harmful gases and polluting environment. The final product is artificial carbon, which owns fixed higher carbon content (about 90%). Compared with the general coal, it is about twice its carbon content.
Our equipment adopts double-layer design, which can make the lower part of the machine contact the hot air as much as possible; meanwhile, this design is helpful to raise the heat utilization efficiency from the beginning. There are three times to make maximum full of heating in the whole process of operation, so the temperature of the emission gas is below 100 centigrade and the heat use ratio of our equipment is over 85%. What’s more, biomass carbonization furnace adopts one fire two step method, which is the only in the world. At present, Kingtiger is the top-class manufacturer for waste to energy machine. There is no other technology equipment could be mentioned with us in the same breath.
Biomass Plant from Kingtiger mainly includes coconut shell carbonization furnace, rice husk carbonization furnace, straw carbonization furnace, palm shell carbonization furnace. This kind of plant could help people to make full use of the crop waste and extract useful materials.
Parameters Of Kingtiger Biomass Carbonization Plant
|Raw material||Various biomasses include organics, rice husk, tree leaves, crop straw, hay, tree barks, shells etc.|
|Dimension (W*H*L)||1.0*1.7*8.0m³||1.3*1.9*8.5 m³||1.6*2.2*8.5 m³||2.2*2.8*8.5 m³||3.0*3.3*8.5 m³|
|Cooling method||Water cooling|
Working Process Of Kingtiger Biogas Technology
- Collect the raw material into the measuring conveyor by the material reclaimer machine;
- The dispersion foggy device in the timber dryer pre- drying out the raw material which will free fall inside the carbonization machine and been dry out for the second time;
- Then material fall in the outside bin of the machine and start the high temperature pyrolysis, sulfur emission, flue gas volatile, carbon focused in the carbonization process;
- The carbide will be discharged by the Water-cool conveyor, and the rest hot flue gas and heat will be suffered desulfurization process and smoke abatement process;
- The smoke abatement and desulfurization steam will be cooled by the condenser and led to the recycle water pool.
- Mainly depending on the heat produced by burning raw material itself and fuel, the moisture starts steaming from ignition to the temperature of furnace rising to 160 ℃. There is almost no change of chemical composition. Evaporation phase
- Initial phase mainly depends on the heat produced by burning raw material, which rises the temperature of furnace to between 160 and 280 ℃. In this moment, raw material begins to turn out thermal decomposition.
- The most suitable temperature is between 280 and 400℃. During this stage, raw material starts sharply thermal decomposition and destructive distillation to charcoal with high temperature.
Suitable Raw Material for Biomass Carbonization Plant
- MSW (Municipal solid waste)
- Livestock waste
- Sewage sludge
- Wood (construction timber, polluted timber, wood chip, sawdust, chipboard）
- Green waste（trees, shrubs, lawn clippings, humus, weeds, Algae）
- Crop waste（ starch crops, sugar crops, oilseed crops, nut shells）
After the process which includes high temperature pyrolysis, volatile gas, sulfur emission, carbon enrichment of garbage disposal technology, the end product we get is artificial carbon which owns fixed higher carbon content (about 90%), Compared with the general coal, it is about twice its carbon content ( usually fixed carbon content of coal is 55% ). Besides, it is a new type of high-grade fuel with good flammability, while some biomass after carbonization has very strong activation (it can be activated up to 75%), There is no doubt that it is an ideal material for manufacturing activated carbon. Activated carbon can be processed by our carbon black processing plant to get fine activated carbon.
Application of End Product
In agriculture, biomass carbon owns characteristics of improving soil, promoting soil aggregation, regulating the microbe in the soil. Moreover, biomass is capable to reduce heavy metal content. In industry, charcoal, coconut shell charcoal and palm shell charcoal are indispensable for making activated charcoal. Sawdust carbon and other biomass carbon can be utilized in smelt. Wood coal is traditional barbecue charcoal.
Advantages Of Kingtiger Carbonization Equipment
- Easy operation, labor saving and no risk.
- Environmental-friendly with unique smoke decontamination equipment.
- High output rate and efficient.
- Durable with special materials.
- Top grade product quality.
Biomass Gasification Plant Equipped with Carbonization Plant from Kingtiger
Otherwise, in order to reduce investment cost of our customers, and to achieve the zero release in the whole carbonization process, Kingtiger has researched and developed a new type of biomass gasification system, which is equipped with carbonization plant. This gasification unit can institute the fuel of coal, natural gas, to heat the carbonization plant at the beginning stage.
In concrete terms, firstly, combustible gas comes from biomass gasification power plant, and then they will be sent into the carbonization equipment for heating at the initial state. Fuel of this gasifier is biomass materials such as rich hull, wood, palm shell and sawdust. The gasification machine can be turned off, when combustible gas sourcing from carbonization equipment can meet itself for running. This gasification system can save energy, and reduce the investment cost.
Technical Specification of Biomass Gasification System from Kingtiger Group
|Biomass gasification plant|
|Host size||2300*3860 (D*H)||2300*4860 (D*H)|
|Raw material||Agriculture waste, wood, sawdust, coconut shell, and other biomass material|
