Alcohol-based fuel is mainly blended with refined methanol, and the national standard methanol calorific value is 4680 kcal. Under normal circumstances, the finished product contains 20%-30% moisture, and the calorific value is lower after adding water, almost 4000 calories. This is the alcohol-based fuel currently used in hotels.

Crude alcohol is also useful. The so-called crude alcohol is methanol with other impurities used in many factories, just like waste engine oil. Because this crude alcohol contains other chemical raw materials, it may contain high calorific value, such as stupidity and fat. Therefore, the calorific value of crude alcohol is higher than that of refined alcohol, which will reach more than 5 thousand calories.

There are also high calorific value alcohol-based fuels, industrial boilers, drying, heating, hot air and so on. It needs a calorific value of 6000 ~ 9000 kcal, which contains some methanol, supplemented by other high-carbon alcohols or substances with high calorific value, and the cost is higher than the fuel cost used in the kitchen. The higher the calorific value, the less the dosage.

In short, the use of alcohol-based fuels will become more and more common, and the technology is constantly updated. Jingjiang Chunming Chemical will answer your questions. If you don't understand, you can continue to ask.
