Gasification & Syngas Technology
How It Works
1. Fuel In-Feed system
The metering bin provides short-term storage and ensures a constant supply of fuel to the gasifier.
The fuel moves through progressive stages of drying pyrolysis, gasification and reduction to ash. Combustion air (20 ñ 30% of stoichiometric), steam and/or oxygen is introduced through the inner and outer cone into the base of the fuel pile. Partial oxidation, pyrolysis and gasification occur at 1500 ñ 1800 deg F
(815 ñ 980 deg C0, and the fuel is converted into syngas
3. Automatic Ash Removal System
The ash migrates to the grate at the bottom of the gasifier where it is removed.
Syngas exits the gasifier at 500-700 deg F (260-370 deg C), the syngas can be combusted in a close-coupled oxidizer.
Typical System Components from Pellets to Syngas
Typically four steps are required to go from municipal solid waste (MSW) to a liquid fuel.
Step #1 the MSW will go through a process facility where all of the recycling products shall be removed such as glass, aluminum, tin, grade 1 and 2 plastics. The remaining products shall be shredded, fiberized, and pelletized.
Step #2 the pellets the sent to the gasifier were it goes through several stages before it is converted into a synthetic fuel “syngas”.
Step #3 the “syngas” goes through several steps were it is cooled, washed and cleaned.
Step #4 the cleaned “syngas” goes through a catalytic reactor were it is converted into a liquid fuel, which is ready to use or be mixed with other bio-fuels.
