AI Technical Summary
Existing biomass gasifiers lack adaptability and the ability to adjust products during the gasification process. They cannot adjust the ratio of biomass fuel gas to biochar, and cannot adapt to changes in upstream raw materials and the flexibility of downstream market demand.
The process of positive pressure biomass gasification and co-production of charcoal is adopted. The supply of fluidizing air and air gasification agent is adjusted by a variable frequency centrifugal fan, the temperature of the fluidized bed gasifier is controlled, the ratio of biomass fuel gas to biomass charcoal is adjusted, and the gasification products are separated and utilized by a cyclone separator and a conveying system.
It enables safe and reliable adjustment of the gasification product ratio under positive pressure, adapting to downstream demand and upstream fuel changes, improving the adaptability and production flexibility of the gasifier, and reducing equipment costs.
