What is a hot explosion?
Hot explosion concerns preheated air that is blown into a blast furnace. The technique is used in metallurgical operations such as steel production to increase the efficiency of the refining process. It works by recycling waste gases that would otherwise have to be ventilated. The burning of these waste gases for preheating air reduces the amount of fuel required in the high furnace and reduces the cost of operation. High carbon fuel, known as coke, is used to heat ore to reduce it to its ingredients, so that the metal can be divided. Hot gases are produced as a by -product of this process.
There are two methods of waste gases. One option is to clean them from any dangerous substances in the environment and vent them from the system. However, this leads to a substantial waste of energy. Instead, the waste gases may be directed by the special stove where they are burned to preheat air, which is subsequently fed to the main explosive furnace.
three or four castesHot explosions are usually aligned along the air intake to the main explosion furnace. At any moment, one stove is generally used, while the others are loaded to a temperature. The unmanned air, known as a cold explosion, is driven by a turbocharger to a stain where it is heated.
After warming up, this air leaves the stove as a hot explosion and is directed to the main line of the pumping furnace. If it is needed to control the temperature, cold air can be added using a mixing line that is connected to the main. The valve controls the release of cold explosion.
Before entering the main chamber of the furnace explosion, a hot explosion enters the structure. This tube has several equally placed nozzles from which a hot explosion is injected into the furniture. These nozzles are known as Tuyeres, and there may be 15 to 40 around the perimeter of the blast furnace, depending on its size.
a hot explosion in a high furnace,Sometimes supplemented with natural gas, it burns together with coke to achieve the necessary temperature for ore processing. Preheating this air improves combustion efficiency and reduces the amount of fuel desired in the main explosion furnace. It can also speed up the production of the final processed metal. This causes considerable saving costs of recycling energy that would otherwise be unnecessary.
