Liquid-Fuel Miniature Inverted Soot Generator
Description
​
Our Liquid-Fuel Miniature Inverted Soot Generator (LF-MISG) can be operated on gaseous or liquid fuels. The LF-MISG integrates a Bronkhorst Controlled Evaporator and Mixer (CEM). The CEM atomizes a liquid and mixes it with a carrier gas (usually ethylene or nitrogen) which is then burnt in our soot generator. The soot generator and the combustion air is also heated to prevent the condensation of fuel vapour in the soot generator. The CEM and soot generator are limited to 200 C which is sufficient for the vaporization of many volatile liquid fuels like gasoline, ethanol, methanol, kerosene, and Jet A1.

Features
​
• Operates on mixture of vaporized liquid fuel and carrier gas. Common liquid fuels are Jet A1, n-dodecane, and kerosene. Inert (e.g. N2) or reactive carrier gases (e.g. ethylene, propane) may be used.
• Inverted flame geometry for a stable soot concentration
• Produces high concentrations of soot
• Concentration and size of soot can be changed by varying fuel, carrier gas, or air flow rates
