Abstract
A flow diverter of a coke catching element is provided. The flow diverter includes a body disposable in a flow field and defining an interior, an upstream end, which is defined relative to the flow field, and a downstream end, which is downstream from the upstream end. At least one of the upstream end and the downstream end is open to the interior and the other of the upstream end and the downstream end is closed. The interior diverges at the one of the upstream end and the downstream end that is open and converges at the other of the upstream end and the downstream end.
Claims20
A flow diverter of a coke catching element, comprising:
- a body disposable in a flow field and defining an interior;
- an upstream end, which is defined relative to the flow field;
- and
- a downstream end, which is downstream from the upstream end,
- wherein:
- at least one of the upstream end and the downstream end is open to the interior and the other of the upstream end and the downstream end is closed, and
- the interior diverges at the one of the upstream end and the downstream end that is open and converges at the other of the upstream end and the downstream end.
A coke catching element, comprising:
- flow diverters arranged in a flow field to form an intervening space with converging and diverging sections,
- at least one of the flow diverters comprising a body defining an interior with upstream and downstream ends defined relative to the flow field,
- the upstream and downstream ends being open and closed, respectively, or closed and open, respectively, to form a stagnant, recirculating flow in the interior via the open one of the upstream and downstream ends to promote coke deposition in the interior at the closed one of the upstream and downstream ends while maintaining a minimal pressure drop in the intervening space.
A fuel system, comprising:
- an engine;
- a fuel tank to supply fuel to the engine;
- and
- a coke catching element interposed between the fuel tank and the engine, the coke catching element comprising screening media to screen fuel supplied to the engine, the screening media comprising:
- flow diverters arranged to form intervening spaces,
- at least one of the flow diverters comprising a body defining an interior with upstream and downstream ends,
- the upstream and downstream ends being open and closed, respectively, or closed and open, respectively, to form a stagnant, recirculating flow in the interior via the open one of the upstream and downstream ends to promote coke deposition in the interior at the closed one of the upstream and downstream ends while maintaining a minimal pressure drop in the intervening space.
