Problems solved by technology

As a result, in order to achieve higher capacities, larger diameter flares with larger Coanda bodies, slots and surfaces are required which become very heavy and costly.
In some cases, the waste flammable gas pressure in a Coanda flare is limited by the process involved and by the geometry of the flare.

Embodiment Construction

[0031] Referring now to the drawings, and particularly to FIGS. 1 and 2, a prior art Coanda flare 10 is illustrated having an upstanding waste flammable gas supply pipe 12 and a Coanda body 14 attached to the top of the supply pipe 12. A circular slot 16 is provided between the top of the pipe 12 and the bottom of the Coanda body 14 through which pressurized waste flammable gas flows at high velocity. The gas follows the Coanda surface until it has turned through approximately 90° thereby producing a very stable and efficient flare device. However, in order to achieve higher capacities, larger diameter waste flammable gas supply pipes, larger Coanda slots and larger Coanda bodies are required which are heavy and costly.

[0032] Referring now to FIGS. 3 and 4, one form of the linear Coanda flare apparatus of the present invention is illustrated and designated by the numeral 18. The linear Coanda flare apparatus 18 comprises an elongated closed end pipe 20 connected to a waste flammabl...

Abstract

Linear Coanda flare apparatus for burning pressurized waste flammable gas are disclosed. The flare apparatus basically comprises an elongated closed end pipe connected to a waste flammable gas supply pipe and having an elongated linear opening therein; and an elongated flammable gas distributor trough positioned adjacent to the elongated linear opening in the closed end pipe with the sides of the distributor trough being positioned adjacent to the outer curved surfaces of the closed end pipe thereby forming slots that discharge pressurized waste flammable gas from inside the closed end pipe over the outer curved surfaces of the closed end pipe.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to linear Coanda flare apparatus and methods of burning waste flammable gas in the apparatus. [0003] 2. Description of the Prior Art [0004] High pressure Coanda flares have been utilized in the oil and gas and petrochemical industries for many years. The flares include a Coanda body having a surface shape similar to a pot that has an enlarged round bottom and a smaller circular top. The Coanda bodies utilized heretofore have been formed from castings or forgings. [0005] The prior art Coanda flares include a Coanda body attached to the top of a vertical pipe whereby a circular slot is formed between the top of the pipe and the bottom of the Coanda body. Pressurized waste flammable gas exits the slot at a velocity that creates low pressure regions at the boundaries of the gas stream. The space between the Coanda body and the gas stream is quickly evacuated by the low pressure which forces...
