  • Hybrid System for fouling control in biomass boilers

    Concerning biomass characterization, the approach for fouling study is adapted from coal scheme. It is well known the slagging/fouling formation mechanisms and its influence in coal power plants [2-10], but there is a lack of information about the effects of ashes in biomass boilers.Learn More

  • Fouling control in biomass boilers | Request PDF

    The behaviour of the medium-sized biomass boilers started up recently shows a dramatically tendency to a rapid fouling of the superheater surfaces that reduce the boiler capacity (Zevenhoven-Onderwater et al., 2000). Therefore, the development of large biomass boilers and the wide use of the biomass to produce electricity is being questioned.Learn More

  • The influence of biomass co-combustion on boiler fouling

    Dec 01, 2006 · In particular, biomass combustion produces fouling in boiler heat transfer equipment, causing a reduction of steam output and boiler efficiency. The traditional approach uses experimental correlations but the problem has not been solved due to the inherent complexity of fouling and it is necessary to develop new techniques and strategies to minimize its consequences.Learn More

    Such increase of biomass in the fuel mixture may drastically change the combustion conditions and influence boiler operation and design (Fig. 2). Because of different chemical composition and properties of biomass in comparison to the coal some exploitation issues, like slagging, fouling, heat transfer, erosion and corrosion are expected.Learn More

  • COAL-FIRED UTILITY BOILERS: SOLVING ASH DEPOSITION

    Apr 01, 2001 · Specifically, the EERC attempted to elucidate the ash-related problems--grate clinkering and heat exchange surface fouling--associated with cofiring coal and biomass in grate-fired systems. Utilization of biomass in stoker boilers designed for coal can be a cause of concern for boiler operators.Learn More

  • Boiler Coking - Boiler Slagging, Biomass Boiler Fouling,

    Mar 01, 2006 · All kinds of biomass analyzed are characterized by higher fouling tendency than coal, resulting in the deterioration of boiler efficiency. The ash from sewage sludge is particularly disadvantageous in this regard (more than 2% points of deterioration by cofiring 20% sludge).Learn More

  • Fouling in biomass fired boilers - DiVA portal

    Compared to boilers fired with coal and oil the biomass-fired boilers have more complications related to both fouling and corrosion on the heat transfer surfaces. After the combustion, unburned inorganic matter in state of vapour, melts and solid particles are transported in the flue gas and may form deposits on heat transfer surfaces.Learn More

  • Heat Transfer Surface Fouling in Boilers - Bright Hub

    Oct 19, 2009 · Fouling on the convective heat transfer surface is caused by condensation of the vaporized volatile inorganic elements in fuel during combustion when the gas temperature decreases.
