16-01-2015· Re: AFBC Boilers vs. CFBC Boilers 06/20/2010 7:15 PM effeciency of CFBC boiler is more then AFBC boilers on part load. u may run boiler on even 25% load, Maintenance is less due to less contact od pressure parts by eroding flue gas, low NOX & COX , but refractory cost is much more high compare to AFBC due to quantity and quality also.
