Incinerator air blower

While burning some garden waste i decided to add a fan to increase the airflow in the incinerator to reduce excessive smoke.
The 24 volt set up worked, although the fan was the wrong way around.
The 240 Volts set up was great, even through the small aperture enough air was injected into the fire to keep it burning very well.

The tank is ex 30 or 50 kVA 3 phase transformer and lasts a lot longer than the humble 44 gallon drum.

A few small unvented caps were popped like popcorn.
