Sažetak
In this paper formation of sulphur trioxide in the furnace of the steam generator was investigated. The mathematical model that could realistically describe SO3 generation and reduction was developed. The model was applied on a real steam generator combustion chamber. Different combustion parameters were varied: the combustion air excess ratio, the magnitude of the swirl of combustion air, the fuel droplet size, and the fuel injection spray angle. The greatest influence on SO3 reduction exhibited the air excess ratio. The problem of this particular case lied in fact that the air excess ratio could not be notably decreased due to incomplete combustion (increase of CO and H2 appearance of the soot and unburned hydrocarbons above legal emission limits) that it would cause. It was shown that by applying the other measures (increasing magnitude of the swirl of combustion air, increasing fuel spray angle and finer spraying i.e. smaller fuel droplet size) simultaneously with the excess air ratio reduction this problem could be alleviated.
