Boiler banks transfer heat from flue gas to evaporate the steam–water mixture. A two-drum boiler bank was very typical in early boilers and is still used in smaller, low-pressure boilers. In small biomass BFB boilers one can often find a boiler bank (i.e., an evaporative heat transfer surface).

Three-drum boiler - Wikipedia

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 …
