Circulating Fluidised Bed Combustion (CFBC) Boilers

STUDY OF CIRCULATING COAL FLUIDIZED BOILERS

The lower section of the first boiler pass consists of the separators located between the boiler first and second pass, CFBC boilers is comparatively less with that of the

Circulating Fluidized Bed Combustion | …

• Circulating fluidized bed combustion boilers are mainly for medium and large power • CFBC boilers offer greater flexibility as shown in Figure 12.9. Table 12.4 brings out the differences between the two combustion systems. CFBC per­formance is better in nearly every way but is more expensive.

CFBC Boiler vs Pulverized Fired Boiler - SlideShare

CFBC Boiler vs Pulverized Fired Boiler (BFBC) at the lower end and circulating FBC (CFBC) at the higher end. 11. Based on the fluidized region of operation, the FBC boilers emerged in following types BFBC or AFBC – Bubbling/Atmospheric Fluidized bed combustion boilers CFBC – Circulating fluidized bed combustion boilers PFBC
