A system for conversion of energy in a residual gas generated in an industrial process. The system includes a combustion chamber having a fuel inlet configured to receive a flow of residual gas for combustion in the combustion chamber. The combustion chamber further includes an air inlet. The system also includes a Stirling engine configured to convert heat from the combustion chamber into mechanical energy, the Stirling engine having a heat exchanger, wherein at least a portion of the heat exchanger extends into the combustion chamber. The system further includes a residual gas duct arranged for transporting the residual gas at atmospheric or near atmospheric pressure and an air duct arranged for transporting air at atmospheric or near atmospheric pressure. The system further includes a gas diffusion chamber including a residual gas inlet through which the residual gas enters the gas diffusion chamber from the residual gas duct, and a residual gas outlet in fluid communication with the fuel inlet of the combustion chamber, wherein the residual gas is transported in a diffusion direction from the residual gas inlet to the residual gas outlet. The gas diffusion chamber has such a shape that the flow of residual gas at the fuel inlet is substantially laminar and has a symmetric velocity profile.

System for recovery of energy from a residual gas

An arrangement for removal of particulates in a gas flow includes at least one gas passage that is at least partly surrounded by a porous material. An arrangement for exposing the gas passage to sound that induces gas movements in a direction towards the porous material is provided. A method for removal of particulates in a gas flow is also provided.

A particulate filtration device includes a filter with a feed inlet side for a feed gas and an filtrate outlet for a filtrate, feed gas channels and filtrate channels, and one or more diaphragms between the feed inlet side and the filtrate outlet. Opposite to the feed inlet side a particulate outlet is arranged with a collector compartment attached to the particulate outlet for collecting particulates retained in the feed gas channels.
