The Experimental Research Of Resistivity Characteristics Of Biomass And Coal's Co-firing Ash

The resistivity of dust is an important parameter in the dust collection performance. This thesis studies the resistivity characteristics of some biomass and co-firing ash on the basis of the experiment. The results show that:The resistivity of biomass ash increases as the raising of temperature and there is no obvious peak;the resistivity of co-firing ash changing with temperature is very similar with fly ash;biomass ash has a very serious slag tendency. The contamination trends of co-firing ash changes light and slag characteristics is approach to original coal along with the continuous adding of biomass. but slag characteristics have increasing trends;wear and tear characteristics of three kinds of biomass is very slight;the hydrophilic characteristics of co-firing ash enhances with wheat blending ratio increases;the wetting property of co-firing ash is hydrophilic with corn blending ratio increases,but the data shows that it has increasing trends;wheat ash adhesion is minimum in the three kinds of biomass ash,corn ash and sawdust ash adhesion are large. The adhesion increased first and then decreases with the proportion of biomass increases.
