Claims
- 1. A method for quenching a hot gas stream flowing in a conduit, comprising the steps of:conveying said hot gas stream through said conduit from an upstream source to a downstream location; inserting flow obstruction means within said conduit; injecting a quenching fluid tangentially into said hot gas stream at a momentum sufficient to cause said quenching fluid to flow circumferentially around the entire inside surface of said conduit; providing a sharp interface between said hot gas stream and said quenching fluid; creating a low-pressure zone in said hot gas stream immediately downstream of said flow obstruction means; filling said low-pressure zone of said hot gas stream with said quenching fluid; and causing said quenching fluid to contact and wet the downstream face of said flow obstruction means.
- 2. The method of claim 1 wherein said quenching fluid is injected downstream of said flow obstruction means.
- 3. The method of claim 1 wherein said quenching fluid is injected at substantially a right angle to said hot gas stream.
- 4. The method of claim 1 wherein said quenching fluid is injected so as to provide a momentum according to the equationU2/(Rg)>1 where: U2 is the square of the inlet velocity, R is the inside radius of quench tube 10, and g is the acceleration of gravity.
