Description

technical field [0001] The invention relates to a biomass carbonization furnace, which belongs to the technical field of biomass pyrolysis carbonization. Background technique [0002] Biomass energy refers to the form of energy produced from biomass raw materials. At present, biomass energy accounts for 14% of the world's total energy consumption, ranking fourth after oil, coal and natural gas. Biomass energy has the characteristics of large reserves, renewable, storable and replaceable, carbon neutral and clean, and has unique advantages in energy utilization and environmental protection. However, the distribution of biomass is very scattered, with various shapes and low energy density, which brings certain difficulties to collection, transportation, storage and utilization. Certain pretreatment measures or conversion technologies must be adopted to make it practical. [0003] Biomass pyrolysis and carbonization technology is a promising biomass energy utilization technol...

AI Technical Summary

Problems solved by technology

Due to the large differences in moisture content and composition structure of different biomass raw materials, this not only affects the carbonization speed of biomass raw materials, but also affects the carbonization quality of biomass

The currently developed smoldering and spiral integrated carbonization furnaces generally have defects such as single processing varieties, poor adaptability of biomass raw materials, difficulty in guaranteeing the yield and quality of biomass charcoal, etc.
