DIFFERENCE BETWEEN AFBC AND CFBC BOILER PDF

Atmospheric fluidised bed combustion boilers - AFBC boilers Atmospheric fluidised-bed combustion AFBC boilers offer efficient, cost effective and reliable steam generation. AFBC technology promises to provide a viable alternative to conventional coal-fired boilers and other solid fuel-fired boilers. These AFBC boilers are designed with no moving parts in the combustor, which ensures reduced maintenance costs. Uniform temperature distribution in the bed along with the agitating characteristic of the fluid bed provide optimum combustion, resulting in a minimum of unburnt fuel, reduced carbon monoxide emissions and improved efficiency. Circulating fluidised bed combustion boilers — CFBC boilers Circulating fluidized-bed combustion CFBC boiler technology offers high reliability and availability coupled with low maintenance costs, and complies with stringent emission regulations. Better Space utilization for large Industrial units b.

Difference between CFB boiler and pulverised coal boiler

Fuel feeding in cfbc boilers? In cfbc boiler fuel system like a very important funtion of in all process. This type of fuel feeding system accept over size of fuel also. In compared with under feeding system this is more reliable. Now these days have some boiler have both feeding system. In under bed feeding coal size crushed approx mm which is throw from conveyer to combustion panel.

AFBC Boiler VS CFBC Boiler

The technology is proven and is in use for nearly a century. Advances over the years have improved the efficiency of combustion, reliability and reduced emissions. The key differences are listed below. PC firing utilises coal ground to a very fine powder sprayed into the furnace for combustion.
