A Gasification System for the Disposal of Industrial Waste and Energy Generation: Experimentation and Thermodynamic Analysis

Abstract

The  present  paper  shows  the  thermodynamic  analysis  of  a gasification system (Fig. 1), which is currently used for the recovery   of   metals   from   contaminated   substances   of organic origin (waste of mechanical process, rolling, cold-drawn, tins, multi-coupled materials, tetra, etc. .), and that, in  this  paper,  is  extended  to  the  energy  recovery  and disposal of Paper Industry Waste. The interest in pyrolysis and  gasification  is  justified  because  these  processes  go over  the  traditional  combustion  systems  of  biomass  and waste. In this system the inert ambient is supported by the smoke coming  from  the  combustion  of  natural  gas  and  it  is possible  to  schematize  it  into  a  line  of  heat  treatment  and in a flue gas cleaning occurring after the combustion. Using   the   results   of   different   experimental   tests   a thermodynamic  and  thermo-chemical  analysis  is  carried out.  Starting  from  the  energy  and  mass  balances  on  the entire  system  and  on  the  each  component,  the  balance  of the gasification reactions is verified.
