Study on the Cold Experiment of a Multi-Combined Circulating Fluidized Bed Gasification

Abstract

The dual fluidized bed biomass gasification technology is an important technology to convert low-quality biomass into high-grade hydrogen. In order to further reduce the tar content in gas, we proposed a new multi-combined circulating fluidized bed gasification basing on the existing researches of the dual fluidized bed gasification. Moreover, we designed and built a cold state test system, focusing on the influence of bed material, low speed area fluidization velocity, the fluidization velocity ratio of high and low speed area to the gasification chamber pressure distribution and the solid circulation of output loop. They will be the foundation for construction and commissioning of multi-combined circulating fluidized bed gasification thermal test system.
