Need for Recovering Exhaust Gas Heat

Boilers for heating or water-feed heating are equipped in apartment complexes, hotels, hospitals, public baths, swimming pools and industrial buildings. These facilities and buildings are heavily populated in the large cities and industrial areas, where city gas or diesel oils are commonly used for the boilersThe outlet temperature of exhaust gas emitted from boiler ranges roughly 200 ~ 250 °C, in which a large volume of water steam gas is included.

With this high outlet temperature, the heat exchanger, attaining to emit the outlet temperature of the exhaust gas between about 30~50 °C, effective recovery of exhaust gas heat and latent heat can be achieved, enabling the recovery rate to the maximum extent. Installing heat exchanger can recover the gas heat and latent heat from the boiler exhaust gases,

 

and the fuel consumption can be reduced saving roughly 7~12% of fuel expenses. As the fuel price is on the increase recently, the economics of the exhaust gas waste heat recovery system of boiler becomes improving. However, the rate of the heat exchanger is currently standing in low supply quantities due to the low-temperature corrosion problems generated from the acidic contents in the boiler exhaust gases. The oil fuel causes the low-temperature corrosions when using oil for boiler fuels.


According to the report of the U.S. Battelle Research Institute, in case of gas boilers, acidic gases are present in the exhaust gases, which cause corrosions due to the accumulated acidic contents in normal heat exchangers.

 

 

This technology has been widely applied to apartment complexes, hospitals, bathing pools and bathhouses, and so on. As developed and localized in joint study with Korea Institute of Energy Research and Hankuk Aviation University through the multi-year efforts, the technology has far superior corrosion-resistant good performance as the condensed type of waste heat recovery system. This condensed type heat exchanger reduces fuel consumption that can be used for various type boilers, reducing the expenses in importing energies, and contributing to the prevention of earth warming phenomena. The installation of the water floating layer type heat exchanger, while accomplishing the reduction of boiler exhaust gases and recovering the energy from boiler exhaust gas, will be a good approach for your energy saving multi-purposes either in businesses or in households.
