基于钙链制氢的双流化床气固流动特性
Gas-solid flow characteristics of a dual fluidized bed reactor based on calcium-looping hydrogen process
摘要
Abstract
Calcium looping hydrogen process(CLHP)is an innovative technology for hydrogen-rich syngas production,a dual fluidized-bed reactor was designed and built,which was mainly composed of a gasifier,a calciner and a carbonator,cyclones,diplegs and loop seals. Two types of different particles sizes of white corundum were employed. The gas-solid flow characteristics of the dual fluidized bed reactor was presented in this work. The effect of total solid inventory,particle sizes,the air flow velocities of L-valve,the gasifier,and the calciner on the solid flow rates were investigated. The solid flow rates increased with the increase of the flow velocities of L-valve,the gasifier. The correlation between the air flow rates of L-valve and solid flow rates had also been investigated. The regression equation was obtained through the dimensional analysis and multiple linear fitting. Results showed that the regression equation was in agreement well with the experimental results. It could better reflect the relationship between the air flow rate of L-valve and solid flow rate.关键词
