Patent ID: 8444411

Claim:
An incinerator for disposing of boil-off gas on an LNG carrier, which incinerator comprises a wall defining a combustion section extending from a proximal end to a distal end wherein the boil-off gas is burned in a stream of combustion air admitted into the combustion section at the proximal end of the combustion section, thereby forming combustion products, and wherein non-combustion dilution air is admitted into the combustion section between the proximal end and the distal end of the combustion section in a stream of non-combustion dilution air separate from the stream of combustion air and subsequently is mixed with the combustion products, wherein the incinerator is configured and arranged so that before being mixed with the combustion products said non-combustion dilution air is admitted into the combustion section separate from the combustion products for being passed along the combustion section between the wall the and the combustion products and contiguous with the combustion products for diluting and cooling the combustion products separating the combustion products from the wall to cool the wall.
