“…However, few in situ measuring systems focus on combustion or flame inside the incinerator. Only two of the studies we reviewed [6,7] used infrared thermographic cameras to replace thermocouples and to obtain a temperature map inside the combustion chambers of incineration plants. These studies demonstrated that in situ monitoring combustion can be helpful, particularly for control and optimization purposes.…”

This paper presents experimental investigations of the in situ diagnosis of the alkali metals in the municipal solid waste (MSW) flame of an industrial grade incinerator using flame emission spectroscopy. The spectral radiation intensities of the MSW flame were obtained using a spectrometer. A linear polynomial fitting method is proposed to uncouple the continuous spectrum and the characteristic line. Based on spectra processing and a non-gray emissivity model, the flame temperature, emissivity, and intensities of the emission of alkali metals were calculated by means of measuring the spectral radiation intensities of the MSW flame. Experimental results indicate that the MSW flame contains alkali metals, including Na, K, and even Rb, and it demonstrates non-gray characteristics in a wavelength range from 500 nm to 900 nm. Peak intensities of the emission of the alkali metals were found to increase when the primary air was high, and the measured temperature varied in the same way as the primary air. The temperature and peak intensities of the lines of emission of the alkali metals may be used to adjust the primary airflow and to manage the feeding of the MSW to control the alkali metals in the MSW flame. It was found that the peak intensity of the K emission line had a linear relationship with the peak intensity of the Na emission line; this correlation may be attributed to their similar physicochemical characteristics in the MSW. The variation trend of the emissivity of the MSW flame and the oxygen content in the flue gas were almost opposite because the increased oxygen content suppressed soot formation and decreased soot emissivity. These results prove that the flame emission spectroscopy technique is feasible for monitoring combustion in the MSW incinerator in situ.

Artificial intelligence (AI) has found widespread application across diverse domains, including residential life and product manufacturing. Municipal solid waste incineration (MSWI) represents a significant avenue for realizing waste-to-energy (WTE) objectives, emphasizing resource reuse and sustainability. Theoretically, AI holds the potential to facilitate optimal control of the MSWI process in terms of achieving minimal pollution emissions and maximal energy efficiency. However, a noticeable shortage exists in the current research of the review literature concerning AI in the field of WTE, particularly MSWI, hindering a focused understanding of future development directions. Consequently, this study conducts an exhaustive survey of AI applications for optimal control, categorizing them into four fundamental aspects: modeling, control, optimization, and maintenance. Timeline diagrams depicting the evolution of AI technologies in the MSWI process are presented to offer an intuitive visual representation. Each category undergoes meticulous classification and description, elucidating the shortcomings and challenges inherent in current research. Furthermore, the study articulates the future development trajectory of AI applications within the four fundamental categories, underscoring the contribution it makes to the field of MSWI and WTE.

“…Careful selection of transmitted wavelengths is critical to avoid such interferences by gas species and for obtaining images of the underlying fuel bed surface. Experimental work was performed at the waste-to-energy (WTE) plant in Coburg, Germany [30]. Two reciprocating grate units burn approximately 300 tons of unprocessed refuse daily, generating a gross thermal power of 40 MW for electricity and district heating.…”

Several laser-based diagnostic techniques for nonintrusive measurements of species concentrations and temperatures were developed during recent years and have become valuable tools to study technical combustion processes. Data gained from such experiments are the basis for a comparison with detailed mathematical modelling of chemical processes in laminar and turbulent flows including heat and species transport. Examples for the application of laser-induced fluorescence (LIF), laser-induced thermal grating spectroscopy (LITGS), Rayleigh scattering (RS), differential absorption (DIAL) and emission in the infrared in ignition processes, internal combustion engines, municipal waste incinerators, and pressurized fluidized bed reactors are described.
