Abstract: A method of removing dust from dust laden gases said method including the sequential steps of: (1) passing a flow of gases laden with dust particles, at a selected first gas stream velocity through a first dust removing mechanism capable of creating multiple vortexes of gases; (2) agglomerating the dust particles of the gases as they pass through the first dust removing mechanism said first gas stream velocity being selected to cause agglomeration of said dust particles; (3) passing the gas stream carrying agglomerated particles at a selected second gas stream velocity through a second dust removing mechanism capable of creating multiple vortexes of gases; (4) removing the agglomerated dust particles as they pass through the second dust removing mechanism at said second gas stream velocity; wherein the second gas stream velocity is substantially slower than the first gas stream velocity.
