Abstract
Abstract A liquid mist for being conveyed by a carrier gas stream is produced from a liquid by atomizing the liquid into the carrier gas stream in the form of a collection of droplets, deflecting the collection of droplets in the carrier gas stream at a deflection region, separating droplets in the collection of droplets which exceed a maximum size from the carrier gas stream, collecting at least a part of the separated droplets on at least one heatable contact surface, and at least partially vaporizing them into the carrier gas stream.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
102 words
A method of producing from a liquid a liquid mist which can be transported in a carrier gas stream, comprising: atomizing the liquid in an atomization region into a carrier gas stream in the form of a collection of droplets, deflecting the collection of droplets in the carrier gas stream at a deflection region, in the deflection region, separating droplets in the collection of droplets which exceed a maximum size from the carrier gas stream, collecting at least a part of the separated droplets on at least one heatable contact surface, and at least partially vaporizing them into the carrier gas stream.
Claim 2
Independent Claim
102 words
A method of producing from a liquid a liquid mist which can be transported in a carrier gas stream, comprising: atomizing the liquid in an atomization region into a carrier gas stream in the form of a collection of droplets, deflecting the collection of droplets in the carrier gas stream at a deflection region, in the deflection region, separating droplets in the collection of droplets which exceed a maximum size from the carrier gas stream, collecting at least a part of the separated droplets on at least one heatable contact surface, and at least partially vaporizing them into the carrier gas stream.
Claim 3
Dependent Claim
30 words
A method according to claim 1, further comprising collecting at least part of the droplets to be vaporized and vaporizing them on a heatable contact surface in the atomization region.
