三种典型低热值气体燃料的层流火焰速度测量
Laminar Flame Speed Measurement of Three Typical Low Calorific Value Gas Fuels
摘要
Abstract
The laminar flame speed of three typical low calorific value (LCV) gases (biomass gasified gas,coal gasified gas,blast furnace gas),methane and ammonia purge gas was measured at atmospheric pressure and ambient temperature,using heat flux method.Equivalence ratios from 0.62 to 2.09 were investigated.The laminar flame speed simulations of these gases were carried out with Chemkin.The results of experiments and Chemkin simulations are very close to each other.Comparing these different gases' experiments and model simulations results,it is found out that the laminar flame speed of these LCV gases is low,which is about 20 cm/s at stoichiometric condition,due to their low heating value (LHV).Laminar flame speed is also influenced by H2 fraction significantly.The LCV gases with bigger H2 fraction have higher laminar flame speed.Besides,CO in the LCV gases makes the peak of laminar flame speed shift to the rich side.关键词
