Improving Air Flow Uniformity at Burner Exit by Effective Flow Distribution in Wind Box Case Study Highlights Client Profile: Power Plant Equipment Manufacturer, Mexico Objective: To improve air flow uniformity at each burner exit by design modification of the wind box. Challenges: = Developing accurate simulation model to obtain
meaningful results = Identify design improvement areas to improve
flow distribution = Provide additional design changes to achieve
The combustion efficiency inside the boiler is highly dependent on the air fuel ratio available for the burner. The wind box utilized to supply air for combustion has to ensure uniform air flow distribution across each burner, in order to ensure complete combustion. However, due to complex wind box design, chances for incomplete combustion are always present, due to the non-uniformity of the air flow across the burners. Optimizing the flow distribution, in a manner where there is uniform air available at every burner exit, maximizes the combustion efficiency and thereby improves the overall plant efficiency.
air flow uniformity at burner exit Solution: The wind box consisting of burner arrangements were first modeled through CAD tools and uniformity across the burner exits was measured. In order to improve the uniformity, use of baffles at several different locations around the burners were suggested. The simulation for the new configuration reduced the flow rate difference below 2 percent, proving the significance of the optimized wind box design. Software Used : ANSYS Fluent 14
A leading power plant manufacturer from Mexico needed a design solution to address similar issue for their wind box, utilized for combustion process in boilers.
The Solution Fluid dynamicists at Hi-Tech provided a cost-effective solution to improve the uniformity in air flow distribution across the burners, through design modification and subsequent CFD simulations. In order to achieve uniformity in flow, the wind box was modified with additional baffles surrounding the burners, to direct the flow uniformly at each burner. It was observed that through different baffle arrangements, the velocity distribution across all the burners improved significantly. The difference in flow rates between the top and bottom burners were reduced by half, indicating better mass flow rate availability for complete combustion. Also, it was measured that the pressure in the first two compartments were comparatively higher, due to accumulation of air due to recirculation.This solution can also be provided using OpenFOAM, STAR CCM+, Abaqus CFD, COMSOL Multiphysics.
Benefits = Enhances combustion efficiency and productivity
of the boiler = Reduced prototyping trials and associated costs = Reduction in exhaust emissions
