“…These two kinds of formation mechanism often exist and interact at the same time in the actual combustion, in different circumstances the share is different. [1,2,3,4] With the continuous accumulation of sediments, the direct hazard is the dramatically decrease of heat transfer ability, the boiler running deviate from the design working conditions; on the other hand, the deposition often thickening with the running time, ultimately reduce the flue gas circulation section, which result in the partial abrasion problem and increase the local ventilation resistance, threat running stability. What more serious is that the high temperature corrosion effect of the chlorine-containing attachment is more remarkable when the metal wall temperature is high.…”

In response to the deposition problem in biomass-fired boiler, inert addictive was tested to inhibit the possibility of coking. The deposition samples collected from final and primary superheater of biomass-fired CFB (circulating fluidized bed) boiler were grinded into fine powder. The inhibitive ability of additive was tested by mixing the deposition sample with different proportions of inhibitor under high temperature. By means of scanning electron microscope (SEM), X-ray diffraction (XRD) and other analytical procedures, the properties of the samples with inhibitor such as microstructure, composition were studied. The inhibitor was also introduced to the industrial biomass CFB boiler to verify its inhibition effect on superheater deposition. Unfortunately, the effect of adding inhibitor in industrial boiler is not certain, though the inhibitor added to the samples is obviously effective in weakening coking in the laboratory scope.
