Exhaust Gas Boiler

 

Exhaust gas boilers produce steam by using the sensible heat of the exhaust gases of marine diesel engines, thus saving thermal energy that otherwise would get lost. 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-side.

The exhaust gases, by passing through the steaming, give up heat and afterwards are sent to the funnel at lower temperatures. Where it is necessary, the exhaust gas boiler can be equipped with an economizer and with a superheater: the first one is fit to preheat feed water, thus increasing heat recovery, the second one is used when superheated steam is required.

The exhaust gases of diesel engines still contain thermal energy that is superior to 30% of the total heating value of the fuel. Therefore it seems extremely necessary and important to recover this residual energy by using exhaust gas boilers that have been developed especially for the continuous and heavy service on motor ships. Exhaust gas boilers are suitable for any type of diesel engines, different type of fired heater, diesel electric power station and so on.

ZBG can provide a variety of flue gas waste heat recovery boilers, including carbon rotary kiln waste heat boiler, float glass kiln waste heat boiler, coke waste heat boiler, chemical industry flue gas waste recovery boiler and so on. if you want to know more information about waste heat boiler, please contact [email protected] or call 86-371-86062323.
