Heat Recovery Generators

Heat recovery generators are thermal machines that employ the heat of exhaust gases to produce hot water, superheated water or steam.
Traditional recovery boilers do not have a furnace, as the water inside them is not heated up with a burner, but just with the heat of fumes conveyed in them.
This process allows most of the thermal energy to be recovered that was, before, dissipated in the furnace. This places recovery boilers among the most advanced tools to increase the energy efficiency of a system.
ICI Caldaie's heat-recovery boilers are made with a design called "fire-tube" boilers. In this kind of boiler, the fumes pass through a bundle of tubes immersed in a volume of water in the boiler's body.
As they pass through the bundle of tubes, the fumes transfer heat to the water and have cooled down when they come out from the chimney. At the same time, thanks to the heat absorbed, the water temperature increases until it turns into steam, based on the application required.

GXC

The GXC series heat-recovery boilers are innovative generators that combine the generation of steam by combustion with heat recovery from hot fumes from external sources. This “free” source is primary, while combustion can be used as a backup or provide the power required if the recovery ...

WHB

The only thermal source of the WHB series heat-recovery boilers are hot recovery fumes with no additional combustion. These are entirely automatic single-block generators equipped with all the accessories to ensure a quick activation. The WHB series features great flexibility in terms of ...
