The whole carbonization process spend few hours. I will introduce the carbonization process according to the temperature. 0-300 ºC is a preheating stage, 300-550 ºC is a carbonization stage, and 550-50 is a cooling stage
When wood is burned, it will produce thermal cracking reaction and generate small molecular products. At about 200 ºC, it mainly produces carbon dioxide, water vapor, formic acid, acetic acid and various flammable gases; at 200 ~ 280 ºC, it produces a small amount of water vapor and carbon monoxide; at 280 ~ 500 ºC, it produces flammable vapor and particles; above 500 ºC, it is mainly carbon, and the generated free radicals have an obvious accelerating effect on combustion.
The stick in the carbonization process will produce a lot of light yellow combustible gas. These gases through the carbonization furnace with there own pipes can make combustible gas diversion to the charring furnace combustion zone to the second fire heating. More environmentally friendly and saving fuel.
Jiutian Biomass dry distillation carbonization furnace is composed of a carbonization furnace body, furnace cover, inner tank, 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; the Carbonization process through charging sealing furnace - preheat drying - anaerobic carbonization - cooling out carbon four steps to complete.
Charging sealing furnace is to prepare carbonized 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 ºC, the process time 1.2-2.0 hours (according to the material moisture content, density, particle size determines the specific heating time), and discharge 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 ºC 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 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 ºC, then open the cover out of charcoal. The total furnace temperature and carbonization time are 3.5-5.5 hours, 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.
Biomass dry distillation carbonization furnace is suitable for: wood, logs, mechanism charcoal, shells, bamboo, and other different shapes of biomass raw materials carbonized.
