A fail-safe back-up filter system for filtering particles from a flow of hot gas in a coal gasifier or the like in the event of a failure of the primary filter system. In the event of a break in one of the primary filter elements of the filtration system, the back-up filters, having a higher porosity than the primary filters, begin to collect particulate matter such that the particulates become embedded in the back-up filter. After a period of time, the back-up filters become clogged and prevent the flow of particle laden gas through the back-up filter a...


A method of removing particulates from a flow of hot gas, comprising: passing said flow of hot gas through a plurality of primary filter elements, each said primary filter element having a membrane having a first porosity, wherein said particulates become collected as cake on said membrane; passing said flow of hot gas through a secondary filter element disposed downstream and adjacent to a corresponding one of said primary filter elements, said secondary filter element having a second porosity greater than said first porosity, wherein said secondary fil...
