Aerosol Generator, In Particular Soot Generator

Abstract

An aerosol generator, in particular a soot generator. The aerosol generator includes a combustion chamber, in which fuel can be burned with an oxidizing agent in at least one soot-particle-creating flame, and a fluid feeding device for feeding fuel and an oxidizing agent into the combustion chamber. The fluid feeding device has at least three feed lines, the outlet-side end portions of which run parallel, so that at least three fluids of different types, in particular gases, can be introduced into the combustion chamber unmixed and in a parallel inflow direction.

What is claimed: 
     
         1 . An aerosol generator, configured as a soot generator, comprising
 a combustion chamber, in which fuel can be burned with an oxidizing agent in at least one soot-particle-creating flame;   a fluid feeding device for feeding the fuel and the oxidizing agent into the combustion chamber;   wherein the fluid feeding device has at least three feed lines each feed line having a respective end portion, the respective end portions of each feed line are arranged parallel to each other so that at least three fluids of different types can be introduced into the combustion chamber unmixed and in a parallel inflow direction.   
     
     
         2 . The aerosol generator according to  claim 1 , wherein the respective end portions of the at least three feed lines are arranged coaxially in one another. 
     
     
         3 . The aerosol generator according to  claim 1 , wherein at least one of
 the respective end portions are arranged lying parallel next to one another; and   the respective end portions are arranged parallel next to one another to form an arrangement of lines with a packing density that is as great as possible.   
     
     
         4 . The aerosol generator according to  claim 1 , wherein the fluid feeding device has one of:
 at least four feed lines;   four feed lines; and   seven feed lines.   
     
     
         5 . The aerosol generator according to  claim 1 , wherein respective outlets of the feed lines are located at a same height with respect to an inflow direction. 
     
     
         6 . The aerosol generator according to  claim 1 , wherein
 a first of the feed lines is connected on an inlet side to a first fluid container containing a first fuel; and   a second of the feed lines is connected on an inlet side to a second fluid container, containing a second fuel.   
     
     
         7 . The aerosol generator according to  claim 4 , wherein
 a third of the feed lines is connected on an inlet side to a third fluid container, containing an oxidizing gas; and   a fourth feed line is connected on an inlet side to a fourth fluid container, containing one of a reactive gas and an inert gas.   
     
     
         8 . The aerosol generator according to  claim 1 , wherein a fluid flow rate can be set in each of the respective feed lines by a regulator. 
     
     
         9 . The aerosol generator according to  claim 1 , wherein the respective end portions of each feed line are arranged parallel to each other so that respective fluids are introduced into the combustion chamber unmixed and in a same inflow direction. 
     
     
         10 . The aerosol generator according to  claim 9 , wherein each feed line is parallel to a longitudinal axis of the combustion chamber. 
     
     
         11 . The aerosol generator according to  claim 10 , wherein each respective end portion of each feed line is arranged in the combustion chamber at a same fixed height from a base of the combustion chamber.
