  • Mechanistic Model for Ash Deposit Formation in Biomass

    The model is used to predict deposit formation rates measured during tests conducted with probes in full-scale suspension-fired biomass boilers. The rates predicted by the model was reasonably able to follow the rates observed in the tests, although with some variation, primarily as overestimations of the deposit formation rates.Learn More

  • Ash Deposition in Biomass Combustion or Co-Firing for

    According to the report by Baxter and Koppejan [95], worldwide approximately 41.5% of 135 coal-fired power plants that have experience co-firing biomass use PFC boilers. However, biomass co-firing in PFCs has encountered both technical and non-technical problems. For example, the co-firing ratio of biomass in most PFC boilers is no more than 10 Learn More
