Abstract

The flare burner has flow tube connected at one end to a Coanda nozzle. One edge of the Coanda nozzle slot contacts the Coand surface. The opposite edge of the slot is a flexible flap, which moves within certain limits when pressure is applied and varies the effective slot width. Steam is used as air entraining medium. The low pressure combustion gas is fed into the stack. The flare unit is held in fixed position relative to coanda nozzle when the flare is in operation. Low pressure combustion gas flows through supply tube (9) whose outlet (8) is zero to 150mm upstream of the Coanda nozzle. The flexible flap (5) can be preloaded against Coand surface.
