Exhaust flow spark arrestor

Abstract

A spark arrestor is provided. The spark arrestor includes a housing and an inlet tube. The inlet tube is configured to receive an exhaust flow into the housing. A first baffle is positioned within the housing. The first baffle has a curved configuration and is placed such that a convex side of the first baffle faces the exhaust flow. A second baffle is positioned within the housing. The first baffle and the second baffle are configured to separate particles from the exhaust flow. An outlet tube is present within the housing and is positioned centrally in relation to the first baffle and the second baffle. An end of the outlet tube is configured to contact a concave side of the first baffle. Further, the outlet tube includes a plurality of perforations at the end. The perforations are configured to receive air separated from the exhaust flow into the outlet tube.

What is claimed is: 
     
         1 . A spark arrestor comprising:
 a housing;   an inlet tube in fluid communication with the housing, the inlet tube configured to receive an exhaust flow into the housing;   a first baffle positioned within the housing, the first baffle having a curved configuration, wherein a convex side of the first baffle is configured to face the exhaust flow;   a second baffle positioned within the housing and in relation to the first baffle, the second baffle sized smaller than the first baffle, wherein the first baffle and the second baffle are configured to separate particles from the exhaust flow; and   an outlet tube disposed at least partially within the housing, the outlet tube positioned centrally in relation to the first baffle and the second baffle, the outlet tube having an end in contact with a concave side of the first baffle, wherein the outlet tube includes a plurality of perforations at the end, the perforations configured to receive air separated from the exhaust flow into the outlet tube.
