Biomass Dry Distillation Carbonization Furnace

【Application】  wood, logs, mechanism charcoal, shells, bamboo and other different shapes of biomass raw materials carbonized.

【Capacity】300-500 kg/8h

【Power】15-22 kw

Biomass dry distillation carbonization furnace is Dingli new model products. The machine adopts an advanced thermal dry distillation carbonization technology. It is greatly increase the carbonization rate from 85% to 98%. Which is easily operation, safe and protection environmental, and high production efficiency, which can save a lot of energy. It is the ideal equipment of coal, gas, oil, power plant. More sets of combined distillation carbonization furnace use the hoisting composite structure. It uses the hanging from the cooling method to shorten the production product date. And the efficiency of charcoal production is improved. meanwhile using a unique carbon gas (volatile hydrogen material and tar etc.) back burning technology. The flue gas produced by carbonization is sufficient usage. In addition to satisfied the demand of heat stove, to achieve energy conservation and environmental protection requirements. The excess gas can be a heat source for dryer. Which can be save a lot of fuel in the production. That is improve the benefit of enterprise. Carbonized without using dynamic electricity. It uses the mobile production, simple and convenient operation. It is an ideal equipment for large-scale charcoal production.

 Working Principle:

 Dingli biomass dry distillation carbonization furnace is composed by carbonization furnace body, furnace cover, inner tank, material cage, combustible gas return pipe, exhaust pipe, flue gas dust removal device, tank lifting device and thermometer. The furnace adopts the principle of anaerobic dry distillation to remove the volatile substances in the biomass, and achieve the purpose of biomass carbonization. Carbonization process have four steps: charging sealing furnace - preheat drying - anaerobic carbonization - cooling carbon. Charging sealing furnace is putting the biomass core rods, shells and other materials into cage. The cage is divided into two or three layers. in turn into the inner tank, cover, lock the buckle, lifting the charging tank into the furnace. Preheat drying in the furnace with wood and other fuel heating, slowly heated from room temperature to 220-250 ℃, the process time 1.2-2.0 hours (according to the material moisture content, density, particle size determines the specific heating time), and discharge the material moisture and the air in the tank. Anaerobic carbonization is the furnace temperature to the beginning of weak yellow smoke in the smoke pipe (hydrogen and other volatile substances) discharge, that is the beginning of carbonization, recovery of combustible gas into the furnace ignition, adjust intake air, maintain the tank temperature 300-450 ℃ for 2.0-3.5 hours (according to the carbonized material density, particle size, and carbonization depth requirements determine the specific temperature and carbonization time). When the furnace is natural flameout, namely for the end of carbonization. Cooling out the carbon is hanging out of the tank from furnace, into the cooling area of natural cooling or spray water cooling, until the inner tank temperature dropped to below 50 ℃, then open the cover out of charcoal. The total furnace temperature and carbonization time is 3.5-5.5 hours. It can complete 3-6 furnace time in 24 hours. Exhaust gas through dust collector treatment to reach discharge standards. 3 sets of carbonization furnace in parallel use, peak shifting carbonization, which can be completely used volatile gas heating carbonization furnace, without using additional fuel.

1. The carbonization furnace tank and cage adopts 304 stainless steel. The price will be negotiated additionally.

2. The unit price does not include lifting frame and electric hoist, denominated separately.

3. Carbonization capacity, temperature and time is decided by the material moisture content, density, particle size and carbonized depth (volatile and reserve amount). While adjust the carbonization process parameters or change the raw material, the equipment daily output will be changes.

4. Dingli company is responsible for the client's site planning, process design, equipment installation guidance and training etc.
