combustion. The results of this field test must be carefully examined to identify the
functional advantages and practicality of the structures.
Combustion methods can be divided into a direct injection method in which fuel
is directly injected into a furnace and an indirect injection method. The combustion
method is selected in accordance with the shape of the furnace, the type of fuel, etc.
The combustion method is the key factor influencing NO x emissions, combustion
quality, flame length, and in-furnace temperature distribution. The difference
