The alcohol-based oil fire directly leads to the unevenness of the alcohol-based market. As a general consumer, there is no professional testing equipment. How to identify the fuel performance? Here are some simple identification methods: 1. There are two or more alcohol-based oil fuels, each of which is placed in a small dish of the same size, ignited at the same time, observe the color of the flame, or use both hands to put the palm above the flame to compare the temperature, calorific value The high temperature is naturally high and the palm feels hotter. 2. It is also possible to boil the same water at the same flow rate of different fuels, and record the time of boiling water, and the natural heat value of the short time is high. 3, you can pour some of the methanol in a white porcelain bowl (cup), directly igniting methanol, burning results: nothing on the wall is refined alcohol, basically the best product; there is a little yellow on the cup wall Layer by layer, indicating that methanol is distilled alcohol, it is OK, it is no problem to use as alcohol-based oil; if there is a layer of black on the wall of the cup, it means that methanol is waste alcohol Without any treatment, such methanol is best not used, because such methanol will have an unpleasant smell when burned, and some will have a blinking phenomenon. If there is something else, it is best not to use this. Concerned about surprises Label: How to identify the advantages and disadvantages of alcohol-based oils?
