[Gasification] Alter NRG Waste Gasification

As I have previously posted to the list the electrical power input to the
AlterNRG process is about 2.5% of the total heat input allowing for the
conversion to electricity.   In the AlterNRG scheme you can think of the
plasma heated bed like a high temperature hot plate that maintains
temperature for conversion at the grate and melts the ash fraction which is
recovered as slag through the bed. Because you have a hot bed it allows you
to control gasification air more closely and make a higher quality gas. It
is still fundamentally an updraft gasifier but with an externally
controllable slagging bed.

Dear Tom


Have you ever seen any figures showing electrical energy consumption
required per kw-hr of output gas energy? 


More specifically, "Plasma energy In" vs "Chemical energy Out"...
