Abstract

The invention provides a biomass in-situ controlled nitrogen gasification co-production thermal charcoal device, based on the double-bed decoupled gasification combustion design, the heat generated in the gasification combustion zone is used in the pyrolysis zone through the heat exchange plate, realizing the biogenesis The combination of material decoupling gasification combustion technology and in-situ nitrogen control can not only realize the synchronous, efficient and clean production of biochar and biomass gas heat products, but also use the advantages of easy process control of this technology to control the quality of products. quality and quantity, and finally realize the flexible and high-value utilization of biomass resources, and can also use a large amount of volatile matter after biomass pyrolysis to reduce NO in flue gas. x Reduction is carried out to achieve NO in the process x In situ control.

Description

technical field [0001] The invention relates to the field of biomass conversion, relates to gasification co-production of thermal char and nitrogen oxide emission control, in particular to a biomass in-situ nitrogen-controlled gasification and co-generation of thermal char device. Background technique [0002] Resources are an important foundation for the survival and development of human society. With the rapid development of the world economy, the consumption of fossil resources continues to increase, and it also brings increasingly serious environmental pollution. The clean and efficient use of resources is an inevitable choice for the world to take the road of sustainable development in the future. Biomass has a large mass, is widely distributed, and is a carbon-neutral renewable resource, which will play an increasingly important role in social production. However, biomass resources vary widely in quality, and are usually high in nitrogen and water content. Due to the...
