Abstract
The present invention is a system for removing particulate matter and aerosols from a gas stream generated by gasification prior to the gas stream being used as fuel in an internal combustion device or as synthesis gas for subsequent processing. The present invention consists of removing excess ash by passing the gas stream through a high temperature cyclone separator cooling the gas stream, oil scrubbing the gas to further cool it and to remove particulates and some tars, passing the gas stream through one or more vortex chambers to remove additional tars, passing the gas stream through a heat exchanger to cool the gas, and finally passing the gas stream through a demister to remove aerosols from the gas.
