Radiative Characteristics of Premixed Coke Oven Gas-Ammonia Swirling Flames - Data

Combustion experiments of premixed Coke Oven Gas (COG) - NH₃ swirling flames were conducted with various COG-NH₃ blends and equivalence ratios, and their radiation characteristics were investigated. Furthermore, a theoretical analysis of internal radiation within the gas combustor is performed, using the measured exhaust gas temperature and concentration data.

In this study, seven cases for NH₃ fraction in the range of 0 ≤ X_NH3 ≤ 0.9 and nine cases for equivalence ratio in the range of 0.6 ≤ Φ ≤ 1.4 were investigated. Data for these conditions are available in an xlsx file, limited to conditions where a stable flame was formed and measurements were possible.

In the xlsx file dataset, rows 5-13 correspond to the equivalence ratio for each data point. Columns C-P show the exhaust gas concentrations of H₂O and CO₂ (vol%, wet) for each X_NH3, and columns Q-W show the NH₃ exhaust gas concentration (ppm, wet). Columns X-AD and AE-AK show the outer wall and exhaust gas temperatures (K), respectively. Columns AL-AR, AS-AY, and AZ-BF show the intensity at wavelengths of 2220 nm, 2600 nm, and 2700 nm, respectively, measured by an infrared spectrometer and normalized by the maximum value. Columns BG-BM and BN-BT show the radiation heat flux (kW/m²) released from the combustor to the wall and the radiation heat flux (kW/m²) absorbed within the combustor, respectively. Finally, columns BU-CA and CB-CH show the net radiation heat flux (kW/m²) originating from H₂O and CO₂, respectively.
