| 中文摘要 | Dimethyl ether (DME) is a promising alternative fuel, and it is friendly to the environment because of it’s little emissions of conventional pollutants. But when combusted DME，it will produce the aldehydes which are toxic to human being and animals. Formaldehyde form and emission characteristics of DME combustion are experimentally investigated in this paper. Based on the GB acetyl acetone spectrophotometry technology, the method used to measure formaldehyde concentration of DME combustion exhaust gas is improved. By analyzing and controlling the important factors at key steps of this method, The experimental result indicated that formaldehyde was a very important intermediate product in DME flames, and it was generated and consumed near the flame front with very high concentration. the emission concentration of formaldehyde in the DME combustion process is over 10 times than that of methane. Therefore, formaldehyde emission in DME combustion process can not be ignored.Formaldehyde concentration increased when fuel equivalence ratio increased. At the same fuel equivalence ratio, higher flame temperature caused higher formaldehyde concentration. |
