Special Issue Information

Dear Colleagues, 

We would like to invite submissions to this Special Issue on Advanced Research on Clean Energy Combustion Diagnosis. 

Due to the background of carbon reduction, clean energy combustion has become a popular and valuable combustion technology, and it is necessary to implement real-time, multidimensional, and multiparameter diagnosis of the clean energy combustion process (flame). Diagnosis is an effective tool that helps us to understand the combustion process, collects original data to develop fuel mechanisms and numerical models, and provides quantitative guidance for improving combustion efficiency and reducing pollutant emissions. With the development of software and hardware, many novel combustion diagnostic techniques have emerged to obtain the speed, temperature, and component concentration distribution of the combustion device, which promote the digitization and intelligence of clean energy combustion. From this perspective, we are committed to facilitating the communication of high-quality studies in this field. 

The topic includes but is not limited to:

  • Clean energy combustion diagnosis and its application;
  • Measurement of speed, temperature, and component concentration distribution;
  • Novel combustion diagnosis technology;
  • Diagnosis algorithm (including machine learning);
  • Software and hardware development;
  • Economy and safety related to diagnostic technology.

Three vanadium-based catalysts were used to remove high concentrations of nitrogen oxides, and the catalysts’ performance of de-NOx and anti-H2O under the high concentrations of NOx were investigated. The V-Mo-W/TiO2 catalysts were tested under 1500 mL/min gas flow (GHSV = 500 h−1, 2.4% NO2, 4.78% NH3, 13% O2, 4% H2O, 5% CO2) and characterized by BET, SEM, EDS, XRD, XPS, H2-TPR, and NH3-TPD; then, their physical and chemical properties were analyzed. The results showed that under the influence of H2O, the NOx conversion of the V-Mo-W/TiO2 catalysts remained above 97% at 200–280 °C indicating that the catalysts had high catalytic activity and strong water resistance. The analysis of the characterization results showed that the larger specific surface area of the catalyst, the higher acid content, stronger redox ability, and higher V4+ and V3+ content were the reasons for the high NOx conversion. The surface area decreased and the microstructure become smoother after the reaction, which may be caused by thermal sintering, but the overall morphology did not change. Comparing the H2-TPR and NH3-TPD of V1.6Mo1.7W1.8/TiO2 before and after NH3-SCR reaction, it was found that the reduction peak and the intensity of the acid sites of the sample had not changed, which indicated that the catalyst had good anti-sintering performance and a long lifetime. This is significant for followup long-term engineering application experiments. Full article

High-alkali coal is rich in alkali metals, which can cause serious effects such as slagging and corrosion on the heating surface during combustion and utilization. A portable spectral system was utilized to simultaneously measure gaseous Na concentration and temperature in a 20 kW slag-tapping combustor and a slagging boiler furnace of a 300 MW power generation unit by flame spontaneous emission spectroscopy (FES) for simultaneous measuring. The result shows that both ZD-FK and ZD-HSQ (Fukang coal and Hongshaquan coal, Xinjiang Zhundong high-alkali coal) combustion flame temperatures are around 1400 °C at the outlet of the cyclone burner while the latter is slightly higher. The sodium concentration in the gas phase increases with the rising of the initial combustion temperature and unit load for one kind of coal, and the level of sodium concentration has a strong correlation with the Na content for different coal. Most of the sodium in the high temperature zone of the furnace exists in the form of gas phase, and more sodium migrates to fly ash. Combined with the analysis of fly ash and liquid slag samples, a closed-loop analysis of the Na migration path could be established. Full article
