Fbc Boilers By Rns International

Banking upon in-depth domain knowledge and years of vast experience, we are engaged in exporting, manufacturing and supplying of FBC Boilers in Delhi, India.

Atmospheric Circulating Fluidized Bed Combustion Boilers (CFBC)
In a circulating system the bed parameters are so maintained as to promote solids elutriation from the bed. They are lifted in a relatively dilute phase in a solids riser, and a down-comer with a cyclone provides a return path for the solids. There are no steam generation tubes immersed in the bed. Generation and super heating of steam takes place in the convection section, water walls, at the exit of the riser.
CFBC boilers are generally more economical than AFBC boilers for industrial application requiring more than 75 a 100 T/hr of steam. For large units, the taller furnace characteristics of CFBC boilers offers better space utilization, greater fuel particle and sorbent residence time for efficient combustion and SO2 capture, and easier application of staged combustion techniques for NOx control than AFBC steam generators.
