  • Online Ash Fouling Prediction for Boiler Heating - MDPI

    Depending on its operating conditions, traditional soot blowing is activated for a fixed time. However, low-frequency soot blowing can cause heat transfer efficiency to decrease. High-frequency soot blowing not only wastes high-pressure steam, but also abrades surface pipes, reducing the working life of a heat exchange device. Therefore, it is necessary to design an online ash fouling Learn More

  • Coal ash. Medical search

    The variations of particle properties (e.g. SiO2 content, viscosity) can be mathematically described by random variables. Since bulk analysis of fly ash gives only the mean values of chosen random variables, it is considered insufficient to describe the fly ash behavior either in boiler slagging/fouling or in different concrete structures.Learn More

    This change was considered to be as a result of the fly ash absorbing heat when recirculated from the bottom of the boiler. The unburnt carbon in fly ash saw a decrease from 14.1% to 7.5% as the recirculation rate increased from 0 to 8 t/h and from 14.1% to 8.8% with a 70% recirculation.Learn More

  • Fault Diagnostics on Steam Boilers and Forecasting System

    The slagging/fouling due to the accession of fireside deposits on the steam boilers decreases boiler efficiency and availability which leads to unexpected shut-downs. Since it is inevitably associated with the three major factors namely the fuel characteristics, boiler operating conditions and ash behavior, this serious slagging/fouling may be reduced by varying the above three factors.Learn More
