The hotel's liquefied gas sometimes emits so much black smoke when it burns that it blackens pots, stainless steel and other kitchen utensils. What's going on? Please answer...

The flame of the liquefied gas stove will emit black smoke, which means the combustion is not complete. It is not only difficult to wash off the pot, but also wastes energy. Possible reasons:

1. Liquefied gas Impure, containing more impurities.

2. If the stove is not up to standard, special stoves for liquefied gas must be used instead of gas or natural gas stoves.
