To retain the continuous supply of heat in the reactor, natural gas is burned from the pressure swing adsorption (PSA) in a furnace. Consequently, there will be the presence of the carbon monoxide, CO and carbon dioxide, CO2 throughout the process. Sign in to download hi-res image Fig. ...
The study showed a very considerable enhancement (by a factor of up to 5) of the carbon oxidation rates in the main gaseous flame reaction zone as compared with the burned gas region, thus indicating the importance of the flame radicals O, OH, and H in controlling the oxidation. ...
The undigested sample was filtered through a glass filter crucible, washed by a pepsin solution, dried at 100 °C in a forced-air oven for 24 h, and weighed for IVDMD calculation. To measure IVOMD, the dried residues were burned in a muffle furnace at 550 °C for 3 h. Within each...
Additionally, the mass burning rate (ρuSu0), where ρu in the density of the unburned mixture, is the eigenvalue of freely propagating flames (e.g., [5]). Freely propagating flames are not realized in experiments due to various stability considerations. Along with heat loss, flame ...
The "prompt" mechanism is the principal source of NO x above 1170 K, because at these higher temperatures there is insufficient time for NO to be produced via N 2O as the intermediate.doi:10.1016/S0010-2180(01)00319-4M Pilawska
where V𝑥x is the volume fraction of species x in the initial unburned fuel–air mixtures. The experimental conditions for the mixing are summarized in Table 2. All experiments were conducted at an unburned mixture temperature of 298 K and variations in the temperature were kept within ±2...
Lean premixed combustion is one of the most common solutions for low-emission power generation, which is connected with gas turbine combustion and emission miti- gation techniques. The method works properly for pure hydrocarbon–air flames but can be insufficient, even for the ammonia-doped flames....
For this reason, only positive ions were driven to the premixed zone to produce the ionic wind effect, while electrons would be removed to the burned zone rapidly, due to their low number density and extremely high mobility (K = 4000 cm2/s/V) [36], which is at least three orders of...
The black brown areas are burned areas and the red areas indicate the locations at which fires began. 3.2.
