Ash related Issues in Biomass Combustion

2014-8-11 · Within ThermalNet, WP2D particularly focuses on ash related issues in biomass combustion. A key deliverable is a report summarizing the issues, which is currently available in draft for comments. In the ash one can distinguish inorganic components contained in the biomass, as well as extraneous inorganic material such as sand.

How Circulating Fluidized Bed Boilers Work?

Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air

Fluidized Bed Boiler - an overview | ScienceDirect Topics

Fluidized bed boilers are commonly operated at relatively low temperatures (e.g., 1500–1700°F or 815–926°C). Consequently, slagging is of minor consideration. Further, ash fusion temperatures are of less concern. However, fouling remains an issue, since …
