An object includes an annular outer body having an end and an interior surface; a first annular inner body disposed inside the annular outer body, the first annular inner body having an exterior surface defining a first annular passage with the interior surface of the annular outer body. The first annular passage includes a first plurality of outlets formed on the end of the annular outer body, the first annular passage receiving a coolant and discharging the coolant adjacent the end of the annular outer body. The object also includes a second annular inner body disposed inside the first annular inner body, the second annular inner body defining a second annular passage with the first annular inner body. Further, the object includes a third annular inner body disposed inside the second annular inner body, with the third annular inner body defining a third annular passage with the second annular inner body; and a fourth annular passage opposite and surrounded by the third annular passage. The object further includes a plurality of suspension elements connecting the interior surface of the annular outer body to the exterior surface of the first annular inner body, each suspension element including a first end connected to a first position on the first inner annular body and a second end connected to a second position on the annular outer body, wherein each first position is angularly circumferentially offset from each second position; and each suspension element is configured to substantially rigidly locate a position of the annular outer body relative to the first annular inner body in axial and lateral directions while permitting controlled deflection in a radial direction wherein the first position of each suspension element is angularly circumferentially offset to provide an imbalanced suspension capable of addressing an imbalanced loading, wherein each suspension element has an at least partially tear-shaped cross-section, and each of the second annular passage, the third annular passage, and the fourth annular passage includes a plurality of outlets formed through the annular outer body, adjacent the end, each of the plurality of outlets for each of the second annular passage, the third annular passage, and the fourth annular passage delivering a gas or fuel adjacent the end of the annular outer body.
