AI Technical Summary
Traditional flare systems maintain a slight positive pressure by purging nitrogen, resulting in high nitrogen consumption and operating costs.
Design a self-sealing positive pressure flare burner, which adopts a fluid sealing cover and floating cover structure. Automatic sealing is achieved by automatic gravity. When the internal gas pressure reaches above 2 kPa, the floating cover is lifted to release the flare gas. When it falls below 2 kPa, it automatically closes and seals.
It reduces nitrogen usage, lowers operating costs, and achieves automated sealing to prevent air from entering the burner housing.
