Bubbling Fluidized Bed or Stoker Which is the Right Choice

the boiler is less than 1% on a fuel efficiency basis. Because there is little to no carryover, BFB systems do not usually have carbon re-injection systems since there are no cinders to capture and re-inject. This also eliminates the need for mechanical dust collectors (MDC) downstream of the boiler.
