First, it depends on what kind of fire is used to burn it. 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 the number of them can be said to be an important condition for reaching the maximum temperature.
Second, iron is the most thermally conductive. Nothing else can compare with it, so iron has been widely used since ancient times.

What are you going to burn?
Alcohol burner. Coke oven.
Oxygen welding.

Agree with the oxyyne flame, which reached more than 1000 °, but certainly not the highest.

Oxy-alkyne flame. "Oxyylene flame" refers to the flame of acetylene (acetylene commonly known as calcium carbide gas, which is produced by the reaction of calcium carbide with water) in oxygen, and its reaction text expression is: acetylene + oxygen carbon dioxide + water.
In this reaction, a large amount of heat is released, so that the temperature of the oxyalkyne flame can reach more than 3000, and the steel will soon melt when it comes into contact with the oxyalkyne flame. Taking advantage of this property, oxyalkyl flames are commonly used in production to weld or cut metals, often referred to as gas welding and gas cutting. gas welding; It is to use the high temperature of the oxy-acetylene flame to fuse two pieces of metal together, the key is to make the metal at high temperature not oxidized by the oxygen in the air, for this reason, the amount of oxygen must be controlled, so that the acetylene combustion is not sufficient. In this way, the flame is reducible due to the presence of carbon monoxide and hydrogen gas produced by the incomplete combustion of acetylene. This flame prevents the metal parts and electrodes to be welded from being oxidized and changes their composition when they are melted, and the weld is not stained by oxides.

The combustion temperature of alcohol can reach 800 degrees, the combustion temperature of carbon can reach 600 degrees, and the combustion temperature of hydrogen can reach 3000 degrees
-
Fire on Earth can reach up to 3000 degrees.
-
The maximum temperature of the fire can be heated to 3200 degrees.
1.The ignition point of paper burning is 183 degrees, and we can use cigarette paper with a relatively high potassium content, so that the paper burns at a temperature of just 200 degrees.
2.Within 10-15 minutes after the fire scene, the temperature of the room where the fire occurred was 400 degrees, which is a relatively hot vapor wave, and you may be asking for flames.
3.The temperature of the outer flame of the alcohol lamp is 600 degrees.
4.The calorific value of hydrogen is very large, and the flame temperature is generally 2830 degrees when burned in the equivalent amount of oxygen.
5.Coke is a commonly used fuel in industry, and the temperature of the general steelmaking furnace is 1700 degrees.
6.Generally, the flame temperature does not exceed 3000 degrees, but these are the temperatures under air conditions and normal heat dissipation, but we can also prevent heat dissipation from accumulating heat to create a higher temperature, for example, we can smelt tungsten, if it is in pure oxygen and prevent heat dissipation from accumulating heat, or burning quickly to accumulate a large amount of heat in a short period of time, this temperature is already very high. Nuclear-powered fuel can go up to a higher level.

It depends on what kind of substance is being heated, what kind of pressure, such as water, the standard atmospheric pressure is the highest at 100 degrees, and the increased pressure can rise to more than 100.
-
The temperature of the flame core of gas cutting can reach more than 3,000 degrees.

Everyone knows that drinking more boiled water in daily life is good for health, but how to boil water and how to drink boiled water are still a lot of attention.
Boiling water can kill bacteria and remove substances harmful to the human body, because tap water is chlorinated, and chlorine interacts with residual organic matter in the water to form toxic carcinogenic compounds such as halogenated hydrocarbons and chloroform. When the water temperature reaches 90, the content of halogenated hydrocarbons rises to 191 micrograms, and chloroform rises to 177 micrograms, both exceeding the national standard by 2 times. When the water temperature reached 100, the levels of halogenated hydrocarbons and chloroform were 110 micrograms and 99 micrograms per liter, respectively. If you continue to boil for 3 minutes, the two substances quickly drop to micrograms and micrograms per liter, respectively, to meet the drinking standard. Therefore, it is best to boil water for about 3 minutes.
In order to save water, some people often reheat the leftover boiled water, which is a bad habit. Because repeated boiling of water will cause the aging of water, it will not only cause the loss of minerals that are beneficial to the human body, but also may produce some harmful substances such as nitrite. Once nitrite enters the human body in large quantities, it can make the red blood cells in the blood lose the function of carrying oxygen, resulting in tissue hypoxia, people will drink this water for a long time will cause nausea, vomiting, headache, nails and lips purple, palpitation and other symptoms, serious can also cause hypoxia, and may even induce cancer.
After getting up in the morning, drink a cup of cold and white, which is good for health. Many people like to dry a glass of boiling water the night before and drink it again the next morning. This is okay when the temperature is not high; For example, in summer, when the temperature exceeds 30 degrees Celsius, the air humidity is high, and the bacteria multiply quickly, the cold boiled water overnight will lose its biological activity, and it is very easy to be contaminated and cause diarrhea.
You can pour half a small cup of boiled water the night before, then cover the lid, and mix the boiling water with warm water the next morning.
In addition, the time of cooling and boiling should not be too long, and the boiling water boiled on the same day is best drunk on the same day. It is best not to drink it again if it is left cool for more than 3 days

Summary. 1. Different references 1. Searing: burning; burn off; Burn out.
Mao Dun "The Death of Jesus" II: "The cities were burned by fire, and the fields were swallowed up by the Gentiles. "2. Heating:
Mao Dun, "Midnight" XVII: "The current Wu Sunfu is no longer the Wu Sunfu of Old Lady Wu two months ago when he was first mourned, and the enthusiasm for developing industry has been heated in his veins. "Third, the focus is different: 1. Burning:
Heat-heating, luminescent chemical reactions. It usually refers to the violent oxidation reaction of heat and light by combining firewood, charcoal, oil, sulfur, and coal gas with oxygen in the air at higher temperatures. "2. Heating:
The process by which a heat source transfers heat energy to a cooler object, making it hot.

It usually refers to the violent oxidation reaction of heat and light by combining firewood, charcoal, oil, sulfur, and coal gas with oxygen in the air at higher temperatures. 2. Heating: The process by which the heat source transfers heat energy to a colder object and makes it hot.
Firing definition: through high temperature treatment, a series of physical and chemical changes are made in the green body to form the expected mineral composition and microstructure, so as to achieve a fixed shape and obtain the required effect. Temperature regime:
Including the heating rate of each stage, the maximum firing nuclear slip temperature and the holding time atmosphere system: the corresponding atmosphere requirements of each stage. (oxidative, neutral, reducing) pressure regime:
In order to ensure the realization of the temperature and atmosphere system, the firing process of the pressure in the kiln is one of the most important processes in the process of ceramic raw and raw wax production, and the development of a scientific and reasonable firing system and accurate implementation is an important guarantee for product quality. Firing temperature: The maximum temperature that should be burned in order to achieve the performance requirements of the product.
Sintering temperature: when the material heating process reaches the minimum porosity and maximum density.
Heating: Increase the temperature. It is also a metaphor for intensifying the intensity of a certain action. Opposite to cooling.
