In this paper, the dynamic deposition behavior of Na-enriching Zhundong coal ash on tube bundles with varying longitudinal and transverse pitches was numerically studied. By using a modified critical viscosity model, an improved CFD model has been established key parameters, including deposit mass morphology, particle trajectories impaction sticking probabilities, as well heat flux distribution, have analyzed. The results show that deposited tubes in first row is, respectively, 1.74 3.80...
Abstract This study verified the effect of steel slag as alternative bed material on ash deposition in circulating fluidised (CFB) burning high‐sodium Zhundong lignite (ZD). Sample ZD was burned a lab‐scale CFB at 950°C, and obtained fly deposits were characterised. Results showed that presence leads to abundance Na (2.39 wt%) ash. Na‐bearing minerals such 2 SO 4 , Si O 5 NaCl low melting points had been identified, resulting severe heat transfer surfaces than with quartz material. could be...
