Previously I posted on a Micro waste oil heater for a small tent. https://bushwalk.com/forum/viewtopic.php?f=53&t=41040 It was batch-fed with sump oil. This post is about adding the convenience of drip-feeding oil from a bulk supply bottle to allow tiny heaters to have a massive burn time. The video below shows the heater with drip feeding in action.
I also used the drip feed on another outrageously tiny oil burner oil pot that is as small as a matchbox. The video below first shows irregular burning with a reduced throttle setting and then regular combustion with an open throttle setting.
The next video shows the recovery of the burner flame after being choked off by the throttle setting.
