火力発電所等の燃焼過程における粒子生成を実験室内で模擬した。モデル混合排気ガスには軽金属(アルカリ)と重金属系の粉末の昇華を用いて、その後の希釈(冷却)と凝縮による粒子化の挙動を計測した研究。火力発電所や室内等の「燃焼の場」における捕集技術の高度化に役に立つ。

Thermal Fluid Analysis by Numerical simulation

The emission of alkali (“light-metals”) and heavy metals in combustion processes is an important contributor to environmental load. We investigated experimentally in the laboratory the generation of particles from model exhaust gases derived from NaCl and CdCl2. An on-line gas-phase measurement system showed that the mean diameters of aerosol particles derived from the evaporation of NaCl and CdCl2 were 35 and 30 nm, respectively, when the dilution ratio of the model gas was 1:20. The value was 50 nm in two-metal co-evaporation (NaCl and CdCl2). These results may be informative for predicting the phenomena related to gas-to-particle conversion at the exit of stationary emission sources.
