Abstract

Biomass being clean and renewable energy with low pollution, the utilization of it can reduce greenhouse gas emissions, solve ecological problems and achieve sustainable development. Biomass gasification is one of the main forms of straw biomass energy utilization, and household biomass gasification system is one form of gasification utilization. Household biomass gasification system with the problems of heating value of gasification gas is low, tar and ash in gasification gas is more and material supply inconvenience, which restricted its application. By reviewing the literature and practical experience, the problems of household biomass gasification system, such as the high impurity content of tar and dust in the gasification gas, poor adaptability of gasifier to raw materials, low calorific value of gasification gas and instability of gasification gas production were summarized; and the key parameters of household gasification system, such as the solid particle size of biomass material, the humidity and compaction degree of biomass material, the height of biological material layer, the flow rate of gasifier agent and the temperature of gasification reaction were analyzed. It will help to optimize the structure of household gasification biomass system and optimize the process parameters, improve the utilization efficiency of household biomass gasification system.
