boiler economizer exhaust heat recovery syste

Boiler Economizer Exhaust Heat Recovery Syste

Exhaust heat from combustion typically leaving the stack and into the atmosphere is instead transferred from the exhaust stream by means of a Cain economizer. This lost BTU is now captured and saved to various heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol, and thermal fluids.

exhaust gas steam boil

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.

Boiler Economizer Types And Efficiency Calculation--Z

There are 2 types of economizers: non-condensing and condensing. Non-condensing economizers. The most common are non-condensing economizers. They are heat exchanger coils‚ usually finned‚ that are located in the flue gas ducting at the exit of the boiler. Typically‚ a non-condensing economizer will raise the overall efficiency by 2% to 4%.

Economizer - an overview | ScienceDirect Topi

The economizer is placed as the last of the flue gas to steam–water heat exchanges. The flue gas flow has a low temperature, so fouling is normally not a big problem. Therefore both the transversal spacing and longitudinal spacing can be tight. Economizers are almost without exception countercurrent heat transfer surfaces.
