Fan Selection For Wood Fired Fire Tube Boiler
Fan Selection For Wood Fired Fire Tube Boiler
(OP)
Now I am Converting A Oil Fired Fire Tube Boiler of 2Ton and 10.54 bar to a Wood Fired Boiler. I have decided to provide Fan for Mechanical Draft.
Please asdvise me whether to select ID Fan or FD Fan.
I have been advised by my friends that use of FD fan is economical in power consumption, blades will not be over heated, discharge rate will be low because density of air is higher than flue gas than in ID Fan, Except that on using FD fan pressure inside furnace will be higher than atm. pressure, so while opening door for charging wood logs on grate, there will be back fire.
Your advice in this regard will be helpful to me.

What Mr.Narashimha says is correct. We often go for single ID fan for small boilers. My Question is Why can't we use only FD fan for such applications, instead of going for ID fan which has many demerits.
I feel demerits in using FD fan is,
## Back fire in furnace, while loading wood logs, since pressure inside furnace is greater than Atmospheric Pressure.
Boiler Specifications Are:
2 Tonnes - 3 Pass - External Furnace Wood Fired -Fire Tube - Horizontal Steam Boiler.
Your valuable ideas and suggestions will be very much helpful to me.
