Because different brands use different carbon, if you use steel carbon, you need a fan.

If it's better, just open it, order a napkin and throw it on the disposable stove, and it will be lit. Pay attention to let it burn in the air for about 15 minutes, and then start the barbecue after the open flame is completely extinguished, otherwise it will soon be out of fire. In addition, don't put aluminum paper on the stove, it will go out due to lack of oxygen.
