In a previous post I called it a Greenhouse Gas machine but maybe it’s really a Tiki Torch.
From the landowner:
This [the flames and black smoke] occurs about 3 or 4 times a day that I am aware of and more often at night. Lasts 5 to 15 minutes, and creates a heavy chemical odor that makes my throat and nose burn. I am concerned that it should not be doing this and that open flames so close to the condensate tanks might not be such a good idea.
Or Greenhouse Gas Machine?
