According to one implementation, a centrifugal oil mist separator includes a duct, a fan and a power transmission mechanism. The duct forms a flow path of a first exhaust gas discharged from an engine. The first exhaust gas includes oil mist. The fan is disposed inside the duct. The power transmission mechanism rotates the fan using energy of a second exhaust gas discharged from the engine. The second exhaust gas includes no oil mist.

A method of separating a fluid includes adding a fluid to a canister of a fluid separator. The canister includes first and second barriers disposed concentrically within the canister that define a first and second annulus within the canister, and a canister rotor having a first magnet associated therewith. The method includes rotating an induction base rotor disposed within an induction base. The induction base rotor includes a second magnet. The canister rotor and the induction base rotor are magnetically coupled and rotating the induction base rotor causes the canister rotor to rotate. The method further includes forming a vortex in the fluid via the rotation of the canister rotor, and the vortex causes the fluid to separate into a first component and a second component.

A combustion system, particle separator and feed system for a combined heat and power system is provided. The system includes a combustion chamber configured to directly combust solid organic material. A combustion system is provided having a pressure vessel and a combustion chamber. The combustion chamber is disposed within the pressure vessel with a space therebetween. A conical plenum is disposed within the combustion chamber that distributes fuel to a perimeter of the combustion chamber. Plenum tubes extend from the conical plenum are configured to lift and suspend the solid organic material and induce a cyclonic flow within the combustion chamber. A port is coupled between an air source and the space, wherein during operation, air flows from the air source through the port and into the space to provide a thermal break between the combustion chamber and the pressure vessel.
