Alcohol-based cookware is a new type of alcohol-based fuel energy-saving cookware, which is an extension of diesel, petroleum and liquefied gas energy-saving cookware. Adding alcohol has the original functions of energy-saving stoves for petroleum, diesel and liquefied gas. It uses environmentally friendly, clean and efficient environment-friendly fuel oil (methanol) as fuel, and cooperates with a specially-made energy-saving furnace core to make the environment-friendly fuel oil burn completely and fully, with high heat conversion efficiency, and the discharged gases are water and carbon dioxide. When in use, there is no smoke, residue, residual liquid and black pot bottom. Moreover, the environmentally-friendly fuel-saving stove adopts brand-new copper glass oil valve and new alcohol-based special cooker, which has accurate oil control and is widely used in families, large and medium-sized restaurants, food stalls, hotels, guesthouses and other users.
