    Shell Boilers | Spirax Sarco

    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 …

    This wastes energy and reduces efficiency. Full modulation, however, means that the boiler keeps firing over the whole range to maximise thermal efficiencyand minimise thermal stresses. This type of control can be fitted to any size boiler, but should always be fitted to boilers rated at over 10 000 kg/h. Advantages of a modulating control system:
