[Gasification] reducing temp. of gasification

[Pete & Sheri]

Hello, Greg.
  I know that the correct solution to tar is to keep the reactor temp up,
but, just in case,
how do YOU test for tar?

Greetings, Jai, and list members.

Reducing tars in gas output, is really quite simple, design a gasifier
that works correctly for the desired feedstock is the main method,
however, you can also design a poorly built gasifier, and use many
cleaning filters after the gasifier, in the gas output pipes.

But really, one must understand what "tars" are, and at what internal
temperature the gasifier runs at, once this is known, then the design
can be re-designed to achive the correct temperature to reduce the
tars BEFORE they enter the gas output area.

In other words, generally 2 or more gasifiers must be built (or the
original one modified) to the point of acceptable level of tars within
the gas output.
