Commercial facility energy recovery configuration alternatives are shown on the following schematic flow chart:
Energy Recovery Options: 1. Syngas Clean-up / Gas Engine
2. Syngas Clean-up / Gas Turbine / HRSG / Steam Turbine
3. Afterburner / HRSG / Steam Turbine / Flue Gas Cleaning
In incineration only this (No. 3) option is possible, since the waste, combusted directly, produces only Off-gas which does not retain any latent calorific value and cannot be used as a fuel.
