【Daily Question 2019】Hydrogen production and hydrogenation section – Question No. 006: Briefly explain the principle of air-induced charring of furnace tubes. At certain temperatures, the char inside the furnace tubes is broken down and burned due to the impact of high-temperature steam and air; the products of combustion along with the unburned char particles are carried away by the airflow. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

At a certain temperature, the coke inside the furnace tubes is broken down, crushed, and burned as a result of the impact of high-temperature steam and air; the products of combustion along with the unburned coke particles are carried away by the airflow.
At a certain temperature, the coke particles inside the furnace tubes are subjected to the impact of high-temperature steam and air, causing them to break apart, burn, and explode. The products of combustion, along with the unburned coke particles, are carried away by the airflow.
The working media that cause the heating furnace tubes to burn are air and steam. The coke inside the tubes burns in contact with air at high temperatures; the combustion products, the unburned coke particles that break apart, and the scale are carried away by air, steam, and combustion gases at high speeds. Air is introduced to supply the oxygen required for the combustion of the coke, while steam serves to control the speed of combustion, remove excess heat, prevent local overheating, reduce the oxygen content in the gases, and thus slow down the rate of combustion, thereby protecting the furnace tubes.
At a certain temperature, the char-like substances inside the furnace tubes are broken apart, crushed, and burned as a result of the impact of high-temperature steam or air; the products of combustion, along with the unburned char particles, are carried away by the gas flow.

The coke inside the furnace tubes burns in contact with air at high temperatures; the products of this combustion, along with the broken unburned coke particles and scale, are carried away by the air and combustion gases at high speeds； Introducing air supplies the oxygen required for the combustion of coke, while the purpose of introducing steam is to control the burning rate, remove excess heat, prevent localized overheating, reduce the oxygen content in the gases, slow down the burning rate, and thus protect the furnace tubes.
