• A review on biomass as a fuel for boilers - ScienceDirect

    Jun 01, 2011 · FBC boilers can burn fuel with a combustion efficiency of over 95% irrespective of ash content. FBC boilers can operate with overall efficiency of 84% (±2%). ii). Reduction in boiler size. High heat transfer rate over a small heat transfer area immersed in the bed result in overall size reduction of the boiler. iii). Fuel flexibilityLearn More

    Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as 'fire tube' or 'smoke tube' boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler water.Learn More
