Ignition point of ethanol vapor
Thread Content
Under what conditions can a mixture of ethanol vapor and air be ignited? What temperature is required? If it is a high-speed airflow, what flow rate should be controlled to avoid danger?
The ignition point of 100% ethanol is 75 degrees Celsius; the lower the concentration when mixed with water, the lower the ignition point. When mixed with flammable substances, the outcome depends on specific circumstances. Alcohol has a very low ignition point, so it burns quickly. Moreover, the boiling point of alcohol is only 78°C, while that of water is 100°C. The key factor is the ratio of ethanol to air in the mixture The flow rate is generally kept at around 30 meters. If combustion is to occur, a two-stage ignition method can be used, with an open flame being used to ignite the mixture.
