The factors impacting carbon content in fly ash of the CFB boiler burning low volatile bean coal and anthracite
such as distribution of coal granules fed
bed pressure
primary secondary air fractions
are analyzed.It is found that controlling the fraction of the particles under 100 μm in feeding coal
lowering the bed pressure
and enhancing secondary air blending can all help to decrease the carbon content in fly ash of the CFB boiler burning low volatile lean coal and anthracite.By operational optimization
the carbon content in fly ash of this CFB boiler can be controlled below 10%.
