Boilers and the like that burn fossil fuels such as coal, oil, and gas are required to operate with as low an excess air ratio as possible from the viewpoint of improving plant efficiency and preventing low-temperature corrosion. however,
As the units of these boilers become larger, most of them are constructed from multi-burner systems, and even if there is a combustion failure in any one of the multi-burners, smoke will be produced. Therefore, the theoretical combustion air amount is 7~
It is operated with an excess air rate of about 15%. In a burner system composed of multiple burners, there are many factors such as product manufacturing errors, air and fuel pressure loss, and differences in branch loss in the early stages of construction, and after construction, wear and tear on the fuel side due to differences in operating hours between burners. Combustion of individual burners and between burners is affected by deterioration factors such as burnout and clogging of some parts. Conventional low excess air combustion methods include equipment improvements such as atomizer atomization, as well as
