Description

Product Application
This burning process is similar to the automatic stocker and quite
useful for small capacity boilers (below *5T/h capacity).This usefulness was proved via the multi fuels flexibility that is
automatically applied (i.e.: fuel is able to be in separated or mixed or be used even with different sizes...).The high efficiency and ease in operation and maintenance are also the strong points of this burning process. This burning process can be combined with the boiler body design of ERK Eckrohrkessel to create the perfect product for the Users.
Principle
The Chain-grate boiler system is equipped with multi-fuel feeding system consisting of:
- Main fuel receiving hopper with weight scale; Fuel feeding belt conveyors.
- Auxiliary fuel receiving hopper with weight scale; Fuel feeding belt conveyors.
After Heating, the flue gas will keep going to the Economizer unit to recover the waste
heat and change to useful heat for the boiler or another purpose.
At this time, the energy in the flue gas has nothing much to recover anymore. It will be
treated by a wet scrubber system or the drying collector (what we call bag flter) before
going to the chimney and eventually into the atmosphere.
