Abstract

Focusing on the combustion characteristics and engineering application value of the constant-pressure sequential burner equipped in the GT36-S5 gas turbine

the structural principles and combustion adjustment mechanisms of the burner in actual operation were systematically elucidated. The effects of characteristic parameters

such as fuel staging ratio

combustion pressure pulsation frequency

and temperature distribution

on the operational stability of the unit were analyzed. By analyzing the process parameters of combustion adjustments under actual operating conditions

the nonlinear response laws of the gas turbine combustion during dynamic load changes were revealed. Specifically addressing the low-temperature operating scenario in winter

the effects of various factors

including fuel staging ratios at various stages

the MET setpoint

and

content

on combustion stability

pulsations in different frequency bands and NO

emissions were analyzed. Results show that the obtained combustion characteristic analysis provides a critical basis for the operation and maintenance of the unit. It can guide on-site personnel to improve combustion stability and equipment reliability in complex environments by adjusting the gas turbine load

the residence time at different load stages

offering significant engineering reference value for the operation optimization of similar heavy-duty gas turbines.
