Abstract


Shortages of fossil energy and its associated environmental degradation leading to the development and utilization of biomass energy attention . The our government Outline sent Biomass effective alternative and complementary positioning for fossil energy . Gasification for power generation , gasification gas heating biomass effective use of , and is particularly suitable for the present stage of technical and economic level . Combustion process is a gasification power generation , an important part of the gasification gas heating , so this paper work to study the combustion characteristics the combustible biomass gas produced in biomass gasification , focuses on the various parameters of combustion and flame the impact . Numerical simulation of the process to select some of the important operating parameters , and to study their impact on the combustion process . These parameters include the size of the burner , the turbulence intensity, air flow, fuel flow , the air-fuel ratio , etc. . Numerical simulation software developed by the Fluid Mechanics Department of the University of Lund, Sweden . Simulation results show that : changing the size of the burner as well as other operating parameters, the impact of the two gases of the combustion process are obvious . There are many similarities in the combustion of biomass gas and methane gas ; However, there are also significant differences . Especially at low flame zone . As biomass gas containing carbon dioxide , the low calorific value, so the low - temperature flame zone , combustion is unstable . To obtain a stable flame , the response to the secondary air to be preheated. Nozzle design a direct relationship to the organization of the combustor flow field layout of the airflow , thereby affecting the combustion characteristics of biomass gas . The paper given in chapter IV of the nozzle design and simulated combustion test system , ready for further simulation result of the verification .
