This is very similar to what hobbyist mushroom growers use in our setups to inoculate substrate in a 'sterile' environment. Other methods include using sterile, hot oven air, buying very expensive equipment, and making a still air box at home with a plastic tote box. Good times.
I think a lot of those options are born out of creativity. Inoculation typically happens from jar to jar or from a jar to a block of substrate for instance. A Bunsen burner would probably work well for many applications in mycology. I only ever used one in cell bio, and only a mini Bunsen in my mushroom hobby.
