With the simulation of combustion condition in the raceway in front of a tuyere, the burning rate of pulverized coal injected into a blast furnace has been experimentally and theoretically investigated. A mathematical model based on some assumptions and analyses is then established and proved basically real by comparing the results measured with those calculated by computer. Some modifications are made to the model for no other reason but the difference between actuality and model, and a mathematical model...

With the simulation of combustion condition in the raceway in front of a tuyere, the burning rate of pulverized coal injected into a blast furnace has been experimentally and theoretically investigated. A mathematical model based on some assumptions and analyses is then established and proved basically real by comparing the results measured with those calculated by computer. Some modifications are made to the model for no other reason but the difference between actuality and model, and a mathematical model describing the behavior of the burning rate of pulverized coal injected during combustion process is therefore obtained to adapt itself to the actual injection conditions in blast furnace. It is found that in case of uniformly stable injection an appropriate amount of which the pulverized coal injects can be up to 140-160 kg per tonne molten iron.

Based on the experimental result in cool state of latest - type of coal - burner gun for injection, It is discussed the model test in heat state for contrast Ⅱ- type and Ⅰ-type with fundament - gun (0- type), and is indicated that the combustion efficiency of Ⅱ- type and Ⅰ - type for injection coal excels fundament-gun (0-type) in the equal combustion condition, in particular the former occupies a dominant position when bitu menite is injected, pulverized coal becomes coare,the temperature of preheated air brings down and coal injected increases in quantity.Oxygen enrichment(1.2%) and hard coal mixing bitumenite (10%) can increase the efficiency of coal combustion, but they produce less effect than the latest -type of coal - burner gun within the framework of the test.
