[Gasification] Reducing air from blower

[drewrt]

A simple way to use a fixed speed fan or blower as a variable speed 
system is to simply allow some of the air being pushed by the fan to 
escape.  If you have a pipe inlet that you attach your blower too now, 
just add a T in between the blower and inlit, then over the open end of 
the T, put a sliding plate.   You now can now infinitely adjust the 
airflow to the gasifier, while leaving the fan running at an appropriate 
speed to cool itself.   You can also just put a restrictor plate on the 
air in side of the blower (I use duct tape for  quick trial runs) but 
you may reduce the air movement  enough to cause the motor to overheat.
