Problems solved by technology

At the same time of biomass pyrolysis, the working conditions are very complicated. The high temperature and high concentration of combustible gas when the equipment is running, if the equipment is not properly sealed, it is very easy to cause deflagration and cause danger.

Biomass pyrolysis requires additional energy to break the molecular chains of cellulose, hemicellulose, lignin and other components in biomass. Therefore, it needs to consume a lot of energy. The traditional oil and gas combustion heating efficiency is low, and energy utilization The efficiency is low and it is easy to cause air and other environmental pollution. It is necessary to purchase additional exhaust gas dust removal and pollutant detection devices, and the equipment cost is high. Although the traditional resistance wire heating has improved heating efficiency compared with oil-gas combustion heating, the heat loss is still very serious. , and the resistance wire is easy to age, the life is short, and the replacement of the resistance wire will increase additional costs
