NOVELTY - The gas cleaner (100) has a first filter (104) that is coupled to a receiver (102). The filter is a fabric filter (114) having coating of an inert material and a second layer. The fabric filter is configured to operate at a temperature range within which the fuel-gas maintains gaseous state. A condenser (106) is coupled to the first filter and is configured to control the temperature of the fuel-gas to obtain condensate by condensing constituents of the fuel-gas that are condensable and to facilitate dissolving constituents of the fuel-gas dissolvable in the condensate.    USE - Gas cleaner for down draft with throat, down draft throat less, updraft gasifier and fluidized based gasifier for producing fuel-gases from base fuels coal wood/woody bio-mass, lignite, fine and coarse biomass, waste and other substances such as coal.    ADVANTAGE - The fabric is provided with a coating of an inert material that increases temperature resistance of the fabric and thus increases its capability to operate at high temperature without getting damaged. The inert material coating is an inorganic coating which enhances the dynamic mechanical properties of the fabric thus gives first filter improved high temperature performance, resistance to thermal excursion and abrasion. The cleaning and/or replacing of filter become very easy as no condensation occurs and water is not used in the process. The fuel gas is extracted from the gasifier and the fuel-gas is combusted till temperature of the fuel gas reaches well above the tar dew point to avoid condensation in fabric filter. The combusting the fuel-gas at the combustor also ensures that the undesired fuel gas gets burned at the combustor and therefore do not get released in the environment and hence preventing environment pollution. The gas cleaner is easy and simple to handle because the undesirable constituents are removed from the fuel-gas without using water scrubbing of the fuel-gas and requires no special heat exchanger. Thus the fuel-gas remains dry and does not require cooling the fuel-gas before removing the suspended particles from the fuel-gas.
