Application and Equipment Modification of Dry Low Nitrogen Combustion Technology for 10 kW Gas Turbine
The synthetic ammonia plant is facing shutdown for rectification due to excessive nitrogen oxides in waste heat boiler,so the gas turbine,the source of excessive nitrogen oxides,was selected for treatment.Analyzing the reasons for high nitrogen oxides in gas turbine exhaust,studying the route of reducing nitrogen oxides,selecting and appling a dry low nitrogen combustion technology.Transforming the diffusion combustion chamber into a dry low nitrogen combustion chamber,implementing overall updates to the high-pressure turbine,and renovating and optimizing supporting facilities such as the control system,hydraulic actuators,gas system,and ventilation system.The nitrogen oxide concentration in the exhaust of the gas turbine was reduced from 140 mg/m3 to below 50 mg/m3,not only achieving the standard NOx emissions of the device,but also reducing the operating energy consumption of the device.
