China Deyuan Marine Fitting Co.,ltd .EGE-series exhaust-gas economizer usually is jointly used with oil-fired boiler to take use of compelling circulation water pipe structure, the produced hot water will go to the oil boiler first, without much heating, the steam needed will be produced here. Without cylindrical boiler shell, the water pipe is also the heat-transferring surface, therefore, compared with natural circulation EGB-series exhaust-gas boiler, EGE-series exhaust-gas economizer is lighter, smaller and more economical when they enjoy the same heating surface.

The most advanced pin-tube is installed in this series economizer as its heat-transferring element; however, the phototube and extended-surface tube can also be installed if there is a particular requirement.
