A key component of a boiler system is an expansion tank attached to the boiler or the nearby heating pipes, which serves to provide space for water and air within the boiler system to expand and contract without damaging pipes or valves. If the expansion tank is missing or not operating properly, pressure in the system may cause the boiler's pressure relief valve to vent water.
There are two main types of fluidised bed combustion boilers: Bubbling fluidized bed (BFB) and circulating fluidised bed (CFB) boilers.
