Exhaust Gas Steam Boiler

In practice it is found that the pinch temperature shall be kept at minimum 25°C as a lower temperature difference will substantially increase the heating surface and the price of the Exhaust Gas Boilers. Exhaust Gas Boilers are normally built to regenerate heat from comparatively large flue gas quantities at a not very high temperature and with a limited pressure loss. To fulfill these demands, the boilers ought to be provided with tubes with extended surfaces on the gas …
