Where is the temperature highest in the fire?

"Fire" is a phenomenon of "gaseous combustibles" combusting! So there will be fire when gaseous combustibles burn! In the case of solid or liquid combustibles, the heat emitted by self-combustion when burned causes the unburned combustibles to vaporize and burn, resulting in flames.

Generally, combustibles with high melting points do not have flames when burned.

The fire is divided into inner flame middle blue flame outer flame, where the highest fire temperature is the middle flame in the middle blue part!

The flame is divided into inner flame, medium flame, and outer flame. The outer flame temperature is the highest.

The color of the fire element changes with its temperature. When the temperature is lower than 1000, the color of the fire is reddish; In the range of 1000 2000, the color of the fire also fades and turns yellow; When the temperature exceeds 2000, the flame will turn pale cyan. As the temperature continues to increase, the fire elemental that reaches 6000 emits an intense white light. Different fuels produce different temperatures, so the color of the flame is of course different, but the determining factor is not the fuel itself"quality", but it can be produced"amount"。

Even if it is the same fuel, the color of the flame will be different in different environments; Take the household gas stove as an example, there is an air regulating port under the stove seat, if the gas is mixed with the air correctly, the normal flame is cyan with a little yellow head, then when the air is not mixed enough, because the combustion is not complete, you will see that it is a yellow flame.

Of course, if you add chemicals to the combustion process, you can change the color, like fireworks.

When the temperature reaches a certain level, colored light is emitted.

Red (2000-3500 degrees Celsius).

Orange (3500-4600 degrees Celsius).

Yellow (4600-5700 degrees Celsius).

Yellow-white (5700-7400 degrees Celsius).

White (7400-11500 degrees Celsius).

Blue and white (11500-25000 degrees Celsius).

Blue (above 25,000 degrees Celsius).

So generally the center of the flame is blue, and the temperature is relatively high.

The temperature of the flame ignited by different materials is different:

1. The temperature when the match is lit: 1000-2000 degrees, and the low point when the matchstick burns, 470 degrees.

2. a gas lamp; Alcohol blowtorch: 800 degrees 2500 degrees.

3. Hydroxide flame; Oxyylene flame: 2500-3000 degrees.

4. Fire: 800 degrees.

5. Alcohol lamp: 600 700 degrees.

6. Lighter: 300-500 degrees.

7. Paper: 200 degrees.

Relationship between flame color and temperature: The essence of a flame is a high-temperature gaseous or plasma substance.

There are two factors that determine the color of the flame, and these two factors are as follows:

1. The temperature of the flame determines the color of the flame, and the flame is a reaction. At low temperatures, it is infrared, and as the temperature rises, the flame changes from red-orange (3000 degrees Celsius) to yellow-white (4000 degrees) to cyan blue (5000 6000 degrees) to purple (7000 degrees or more) to finally invisible ultraviolet rays (tens of thousands of degrees). From the perspective of high-energy physics, the flames in the infrared and colored spectral bands are all low-energy flames, and the temperature continues to be high, and the color of the flame ranges from ultraviolet rays to X-rays to gamma rays, etc., which are indescribable "colors".

2. The elemental composition of gaseous and plasma substances determines the intrinsic spectrum of flames, and each element in the element table will emit its own specific light color at high temperature, such as sodium will appear yellow, potassium will be purple, copper will be green, and the light color of the compound is a variegated color, because there are many kinds of elements that are emitting. This is also the reason why the colors of the various flames are different.

The temperature of the fire is not fixed.

Because the flame temperature is determined by the composition of the combustible. For example, the temperature of the flame is more than 600 degrees when wood is burned, the temperature of the flame is more than 1000 degrees when coal is burned, and the temperature of the flame can reach 1400 degrees when hydrogen is burned. An open flame is a fire that really burns in nature, a fire that can be seen, like a visible flame, a visible spark, a candle and so on.

Different substances will be different, depending on the melting point, even if the same substance is burned, the flame will cause temperature differences due to different parts, such as the high external temperature of the alcohol lamp combustion flame, and the internal temperature of cigarette combustion can be as high as 800 degrees.

How did fire originate?

In ancient times, our ancestors had no ability to cultivate, no source of fire, and they only hunted animals for raw food. This era is known as the era of "Ru Mao Drinking Blood". Later, due to the continuous volcanic eruptions, lightning strikes and lightning flashes caused forest fires.

These fires are called "natural fires". After this phenomenon, some of the animals that were burned to death by the fire emitted a fragrance.

Our ancestors believed that animals that had been burned by fire were far better than those that were raw. People are starting to change from raw food to cooked food. Some anthropologists believe that the Yuanmou people who lived in China 1.7 million years ago began to use fire, and they led the fire to the caves, where firewood was often put into the caves to form a fire that was not easy to extinguish for people to use.

This is the preservation of the earliest fires. According to the available data, humans have been using fire since 500,000-600,000 years ago.

Around 12 degrees.

Microwave ovens are mainly divided into three levels: high heat, medium heat and low heat, and different temperatures are used to make non-sail food. Among them, medium fire is divided into medium and low fire, medium fire and medium high fire. Medium fire is also known as civil and military fire or slow fire, the fire power is between the strong fire and the small fire, the fire letter this pillar slightly protrudes from the edge of the pot, the flame is low and unstable.

The temperature of the flame ignited by the substance of different materials is different:

1. Lighter: 300-500 degrees.

2. Paper: 200 degrees.

3. Furnace fire: 800 degrees.

4. The temperature when the match is lit: 1000-2000 degrees, but the low point when the matchstick burns, 470 degrees.

5. Alcohol lamp.

600-700 degrees.

6. Gas lamp and alcohol blowtorch.

800-2500 degrees.

7. Oxygen-oxygen flame Oxy-alkyne flame: 2500-3000 degrees.

Conditions under which the flame burns:

Combustion must have three conditions at the same time: combustibles, combustibles, and ignition sources.

Combustibles refer to substances that can be burned with oxygen or other oxidants in the air, such as wood, natural gas, petroleum, etc.

Combustibles refer to substances that can react with combustible substances, generally referring to oxygen and oxidants, mainly referring to oxygen in the air.

Ignition source, also known as (zháo) ignition source, refers to a thermal energy source with a certain amount of energy that can cause the combustion of combustibles. There are mainly open flames, electric sparks, friction sparks, etc.

Summary. Hello dear, I have been waiting for a long time, and the temperature of the fire can vary depending on its type and burning conditions. In general, the temperature range of a common flame is between 500°C and 1500°C, for example, the temperature of a wood-burning campfire is around 800°C to 1000°C.

However, some high-temperature flames can exceed 2000°C in flamethrowers, rocket engines, and high-temperature furnaces. The maximum temperature of the flame can reach about 3500°C. (Information ** in the headlines).

Hello dear, I have been waiting for a long time, and the temperature of the fire can vary depending on its type and burning conditions. Generally speaking, the temperature range of common macro flames is between 500°C and 1500°C, for example, the temperature of a wood-burning campfire is about 800°C to 1000°C. However, some high-temperature ignition sources can exceed 2000°C for flames in flamethrowers, rocket engines, and high-temperature furnaces.

The maximum temperature of the fire shield can reach about 3500°C. (Information ** in the headlines).

Precautions: Keep a safe distance: A hot flame may produce strong radiant heat, and a safe distance needs to be kept to avoid burns.

Wear appropriate protective gear: For hot flames, wearing appropriate protective gear can provide additional safety protection, such as fireproof clothing, heat-resistant gloves, and goggles. Make sure there is good ventilation:

When dealing with high-temperature flames, it is necessary to ensure that the surrounding area of the chain is well ventilated to avoid inhalation of harmful gases. Note imitation of positive ignition source: The high-temperature flame has a high combustion capacity, and it is necessary to pay attention to the surrounding combustibles and fire sources to avoid fire accidents.

Question 1: What is the maximum temperature of the fire What is the highest temperature of the fire The temperature of the fire has a lot to do with the color, the temperature of red and blue is not very high, and the temperature is highest when it is bright white. It is related to the combustion area and oxygen concentration, and their amount can be said to be an important condition for reaching the maximum temperature

Question 2: What is the maximum temperature of the fire The flame of the fire is divided into the inner flame, the flame core, and the outer flame, of which the inner flame temperature is 120-150 degrees, and the outer flame: The outer flame temperature of the alcohol lamp is 400-500.

The flame temperature of the alcohol blowtorch can reach 800-1200. However, the outer flame temperature of natural gas is much higher than this temperature, probably above 3000.

Question 3: What is the maximum temperature of fire There are many kinds of fire, the common fire is gas + oxygen combustion, and acetylene + oxygen combustion, and the temperature is different. The star is blessed with fire, a nuclear reactor.

Question 4: What is the highest temperature of fire? The temperature of the fire has a lot to do with the color, the temperature of red and blue is not very high, and the temperature is highest when it is bright white. It is related to the burning area and oxygen concentration, and the number of them can be said to be an important condition for reaching the maximum temperature.

Question 5: What is the maximum temperature of the fire This statement is not true in itself. The combustion temperature of different materials is different, some are high, some are low, for example, the fire temperature produced by the natural temperature of white phosphorus is up to 40 degrees, and the instantaneous temperature of hydrogen fusion combustion can reach hundreds of millions of degrees.

Question 6: What is the name of the fire with a relatively high temperature in the lighter The fire in the lighter can be divided into flame core, inner flame, and outer flame. The outer flame has the highest temperature and the core flame has the lowest temperature.

Question 7: What is the maximum temperature of various fuel combustion? Medium Wax? The oxylene flame combustion temperature can reach more than 3200 degrees and is used to cut metal.
