Supplemental Firing - an overview | ScienceDirect Topi

Figure 1-88 shows a schematic diagram of a supplementary fired exhaust gas steam generator. Raising the inlet temperature at the waste-heat boiler allows a significant reduction in the heat transfer area and, consequently, the cost. Typically, as the gas turbine exhaust has ample oxygen, duct burners can conveniently be used.

The condensing economizer can thus recover the sensible and latent heat in the steam condensate contained in the flue gases for the process. The economizer is made of an aluminium and stainless steel alloy. The gases pass through the cylinder and the water through the finned tubes. It condenses about 11% of the water contained in the gases.

Exhaust Gas Steam Boil

Exhaust Gas Boilers also known as Exhaust Gas Economizers, with extended heating surface, used for waste heat recovery in motor ships. A diesel engine loses approximately 30% of the energy to the exhaust gases. A turbocharger recover some of it, but there is still heat losses that can be recovered by means of an Exhaust Gas Boiler, EGB.
