many people ask, I tell you as an actual operator that alcohol fuel has existed for a long time, and now it is popular in restaurants all over the country. The methanol restaurant you mentioned is called alcohol fuel, which is also called environmental oil and bio-oil. This formula is only simple to make, mainly industrial alcohol, mixed with some water and some additives, and circulated by a water pump. It is not technically difficult, and it can be used with the modification of the original liquefied gas furnace core.
