Improved flare apparatus having long service lives for burning flammable and air and methods are provided. The flare apparatus is basically comprised of an outer tubular member and an inner tubular member positioned within the outer tubular member whereby an annular flammable gas discharge space is provided immediately adjacent to an annular air discharge space. The flammable gas is discharged into the atmosphere in an annular straight out pattern. At least a portion of the air is discharged into the atmosphere for mixing with the flammable gas in a swirling pattern immediately adjacent to the flammable gas which prevents internal burning and premature failure of the flare apparatus.

Flare apparatus and methods

The present invention provides improved acoustic flame detection apparatus and methods for detecting the presence or non-presence of a flame from a location remote from the flame. The flame detection apparatus is comprised of a conduit extending between the location of the flame to be detected and the remote location, a sound detector connected to the conduit for detecting sound conducted to it by the conduit and generating a signal representative thereof and means for receiving the signal and indicating the presence or non-presence of the flame in response thereto.

A regenerative thermal oxidizer is provided with a combustion chamber and a plurality of heat transfer columns. Heat transfer media within the columns include solid surfaces which define vapor flow passages. To permit higher volumetric vapor flow rates nearer the combustion chamber, the passages are larger in cross-sectional area and the solid surfaces have less total surface area in those portions of the heat transfer media nearer the combustion chamber than in those portions away from the combustion chamber. The larger cross-sectional area of the passages and reduced area of the solid surfaces decreases the resistance to vapor flow and allows the passages to accommodate the higher volumetric flow rate of the vapor stream passing through the hotter portions of the heat transfer media. The relatively smaller cross-sectional area of the passages and increased area of the solid surfaces in that portion of the heat transfer media located away from the combustion chamber allows for more efficient heat transfer between the media and the vapor stream in those cooler portions of the heat transfer media.
