technical field

The utility model relates to the field of liquid burners, in particular to an alcohol-based liquid fuel gasification burner capable of preventing fire failure.

Background technique

The burner is an essential heating tool for households, catering, hot pot restaurants and field operations. At present, due to the shortage of oil resources, the liquefied gas refined from oil is in short supply. In addition, the investment in laying natural gas pipelines is huge and the cycle is long. Therefore, the market supply Insufficient, severe shortage; Diesel and kerosene are prohibited from being used in catering, industry and other industries due to their high prices, no promotional value, and serious pollution. In order not to be affected by oil resources, various countries have increased their efforts to develop other alternative energy sources. As a kind of renewable energy, methanol and ethanol have been paid attention to by various countries, and they have all increased the development and utilization of liquid fuels mainly based on methanol and ethanol, and the alcohol-based liquid fuel mainly produced by methanol is used as a kind of Large-scale promotion of clean energy can change the current situation of serious environmental pollution caused by liquefied petroleum gas, natural gas, diesel, and kerosene as fuels.

Methanol (Methanol, dried, CH4O) is the simplest saturated monohydric alcohol, with CAS numbers of 67-56-1 and 170082-17-4, molecular weight of 32.04, and boiling point of 64.7°C. Also known as "wood alcohol" or "wood essence". It is a colorless, volatile liquid with alcohol odor.

Methanol belongs to renewable energy and is a liquid at room temperature.
