What is the principle of alcohol blowtorch and what is the difference between alcohol lamp and alcoh

How the alcohol blowtorch works:

The fire power of the alcohol blowtorch mainly depends on the combustion of alcohol mixed with air and vapor to obtain a high-temperature flame.

There are two types of alcohol blowtorches: seated and hanging.

The alcohol of the seated blowtorch is stored in the lamp holder, and the alcohol storage tank of the hanging blowtorch is suspended at a high place.

The flame temperature of the alcohol blowtorch can reach about 1000.

Before use, the preheating basin is filled with alcohol, and the copper lamp is heated after being lit; When the alcohol in the basin is almost burned, turn on the switch on the lamp (turn counterclockwise); The alcohol from the tank is heated and vaporized in the lamp tube and mixed with the air from the pores; At this time, the nozzle gas is ignited with fire, and a high-temperature flame is generated; Adjust the on/off valve to control the size of the flame.

When it is finished, the hanging blowtorch holder can be extinguished by tightening the switch and closing the live plug under the alcohol tank.

How it works. The fire power of the blowtorch mainly depends on the combustion of alcohol mixed with air and vapor to obtain a high-temperature flame.

There are two commonly used alcohol blowtorches: seated alcohol blowtorch and hanging alcohol blowtorch. The alcohol of the seated alcohol blowtorch is stored in the lampholder, and the alcohol storage tank of the hanging blowtorch is suspended at a high place. The flame temperature of the alcohol blowtorch can reach about 1000.

Before use, the preheating basin is filled with alcohol, and the copper lamp is heated after being lit; When the alcohol in the basin is almost burned, turn on the switch on the lamp (turn counterclockwise); The alcohol from the tank is heated and vaporized in the lamp tube and mixed with the air from the pores; At this time, the nozzle gas is ignited with fire, and a high-temperature flame is generated; Adjust the on/off valve to control the size of the flame. After use, the hanging blowtorch holder can be extinguished by tightening the switch and closing the live bolt under the alcohol storage tank at the same time.

1. The temperature is different

The flame temperature of the alcohol blowtorch can reach about 1000.

The thermal temperature of the alcohol lamp reaches more than 400-1000.

2. The flame is different

The alcohol blowtorch flame is concentrated and is not affected by the natural environment.

Alcohol lamps are influenced by the natural environment.

3. The burning object is different.

Alcohol blowtorch burns alcohol vapor.

Alcohol lamps burn liquids.

Proper use of alcohol blowtorch:

1. The alcohol lamp must be lit with a burning match, and one alcohol lamp must not be used to light another alcohol lamp. Otherwise, the alcohol can easily overflow and lead to disaster.

2. Heating requirements: If there are no special requirements in the heating process, the equipment is usually heated by an external flame. The distance between the heating device and the lamp flame should be appropriate, not too high and not too low. The distance from the flame of the lamp is usually regulated by the height of the wooden or iron ring of the lamp.

3. When the heating is complete or when you need to add alcohol and need to extinguish the flame of the lamp, you can use the lamp head to cover it. If it is a glass lamp head, it needs to be closed after the lid is extinguished, and the alcohol vapor is released to let the air in, so as to avoid negative pressure in the lid after cooling and prevent the lid from opening.

4. Storage conditions: The lid of the alcohol lamp that is not used must be covered to avoid the alcohol from volatilizing, because the alcohol in the alcohol lamp is not pure alcohol, so there will be water on the wick after volatilization, resulting in the alcohol lamp cannot be ignited.

5. Storage method: When the alcohol lamp is not in use, cover the lamp cap. If not used for a long time, the alcohol in the lamp should be poured out to avoid volatilization. At the same time, a small piece of paper should be clamped between the lamp head and the lamp neck to prevent sticking.

Precautions and maintenance:

1. It is strictly forbidden to use a blowtorch for open welding.

2. It is strictly forbidden to use other heat sources to heat the lamp pot. When the blowtorch is working, there must not be any heat source under the lamp holder, and the ambient temperature should generally be below 35, and there should be no flammable materials around.

3. If the blowtorch still cannot be lit after two preheatings, it should be temporarily stopped. Check whether there is air leakage at the interface (can be ignited by a match), whether the nozzle is blocked (can be dredged with a probe) and whether the wick is intact (the wick is scorched and should be replaced if it becomes thinner), and it can be used only after repair.

4. Before opening the switch and igniting the nozzle gas, the lamp must be fully heated, otherwise the alcohol cannot be fully vaporized, and liquid alcohol will be sprayed out from the nozzle, which may form a "fire rain" (especially the hanging blowtorch), and even lead to disasters.

5. The continuous use time of the blowtorch is 30 to 40 minutes. If the use time is too long, the temperature of the lamp pot will gradually rise, resulting in excessive pressure inside the light pot, and the blowtorch will be in danger of cracking.

A4Do not use it continuously for too long at a time. If it is found that the temperature of the lamp body rises or the alcohol in the tank boils (there is a bubble bursting sound), it should be stopped immediately to avoid the cracking of the tank body due to the increase of pressure in the tank. Hope it helps you and I wish you happiness and happiness every day! 欄欄

1. Preparation. Unscrew the filled with alcohol on the body of the kettle, and pour the alcohol into the kettle through the funnel between 2 5 2 3 of the total capacity of the kettle, not too full, not too little. If it is too full, it is easy to be dangerous, and if it is too little, the wick will be scorched, which will affect the combustion effect.

Tighten the so that it does not leak.

2. Note: Due to the thin alcohol vapor nozzle in the lamp (the diameter of the common model is millimeters), it is easy to be blocked by ash particles, etc., so that it is difficult to ignite. Therefore, the spout should be inspected before each use, and if a blockage is found, the spout should be pierced with a through needle or a thin steel needle.

For new lamps or blowtorches that have not been used for a long time, the lamp body needs to be reversed 2 or 3 times before lighting to soak the wick in alcohol.

3. Preheating and ignition. Place the blowtorch on an asbestos board or large asbestos net (to prevent the alcohol from being sprayed during preheating from ignition) and turn the air conditioner to minimize the air intake. Pour about 2 3 volumes of alcohol into the preheated dish and set it on fire.

When the alcohol in the preheating tube is heated and vaporized and ejected from the nozzle, the flame burning in the preheating plate ignites the ejected alcohol vapor. Sometimes it is also necessary to light it with a match.

4. When the nozzle flame is ignited, adjust the air intake volume through the air adjustment rod to make the flame reach the required temperature. In general, the more air that enters, the higher the flame temperature.

5. Turn off the heat. When it is not in use, the nozzle mouth can be covered with asbestos net or waste wood board, and the flame can generally be extinguished. While covering the nozzle, you can also use a damp cloth to cool the lamp holder and increase the air intake to turn off the fire.

Later, put a cloth (to prevent scalding) and loosen the (copper cap) on the body of the kettle to let out the alcohol vapor in the kettle.

6. After the blowtorch is used, the remaining alcohol should be poured out.
