“…The causes of agglomeration are not usually clear. CWSF droplets agglomerate as they dry even under ambient conditions (19,26). When the CWSF contains no additives the agglomeration must result from coal particle surface interactions.…”

“…When the CWSF contains no additives the agglomeration must result from coal particle surface interactions. Because agglomerates of all ranks remain intact after the water evaporates, the mechanism binding the agglomerate is independent of coal rank (26). Monolayers of water adsorbed by the coal could serve to hold the particles together (26,27).…”

Combustion technology of coal-water fuels creates a number of new possibilities to organize the combustion process fulfilling contemporary requirements e. g in the environment protection. Therefore an in-depth analysis is necessary to examine the technical application of coal as energy fuel in the form of suspension. The paper undertakes the complex research of the coal with coal-mule and biomass cocombustion. The mathematical model enables the prognosis for change of the surface and the centre temperatures and a mass loss of the fuel during combustion in air and in the fluidized bed.

This study presented a novel diagnosis for the combustion of coal−water slurry (CWS) in a pilot-scale slag-tap vertical cyclone furnace using flame images and three-dimensional temperature distributions reconstructed from these flame images through a two-step inverse radiation analysis. The accuracy of the reconstructed temperature was evaluated by infrared thermometer measurements, with a discrepancy of less than 50 K. The effects of the air/fuel equivalence ratio, the air distribution pattern, and the furnace load on combustion performance were analyzed based on the reconstructed temperature profiles. Experimental and analytical results showed that flame stability was clearly represented by the variance of the image pixel values. The three-dimensional temperature profiles also effectively illustrated the combustion characteristics in the cyclone furnace under different air/fuel settings. By appropriately supplying air, the combustion efficiency of CWS can be maintained at >99% in the proposed cyclone furnace.
