摘要

从化学反应和传热两个方面考虑，建立了生物质间接供热气化模型，包括化学反应和传热两个子模型。化学反应子模型可以预测产气主要成分以及气化反应需要的热量，而传热子模型则可以估算热管的总热阻和传热功率。在模型分析基础上，开发设计了热管式生物质气化炉，并对化学反应子模型进行了验证。结果表明生物质间接供热气化模型成功地预测了产气主要成分，在利用热管间接供热的生物质气化产气中氢气含量在50%～60%之间，并且气体热值较高，可达10 MJ·m-3

Abstract

A mathematical model of indirectly heated biomass gasification was developed consisting of chemical reaction and heat transfer submodels was developed.The chemical reaction submodel could predict the main components of the product gas as well as the external heat required for biomass gasification.The heat transfer submodel could estimate the total thermal resistance and heat transfer rate of heat pipe.Based on the analysis of two submodels

a heat pipe biomass gasifier was designed.Experiments were carried out in the heat pipe biomass gasifier to validate the chemical reaction submodel.The results showed that the chemical reaction submodel was accurate for the prediction of the main components of the product gas.The percentage of hydrogen in the product gas was about 50%—60% and the heating value of the product gas could reach 10 MJ·m-3 in the heat pipe biomass gasifier.
