Abstract：

This paper described the characteristic of air dynamic field distribution situation in a six corners tangentially boiler after the retrofit by using the air gradation combustion technology. The result is shown that, it can be concluded that the air gradation combustion technology is useful to ensure the lignite steady combustion under lower load, control the emission of NO x and reduce the slagging phenomenon in a six corners tangentially boiler.

Key Words： air gradation combustion technology; six corners tangentially; low NO x ; steady combustion.
