Abstract
Entrained particles from an exhaust gas stream may be removed from the gas stream with a device including a housing having a top, an inner surface, and a bottom with a hole passing therethrough, where the housing further includes an impact surface. An entrance pipe guides the exhaust gas stream into the housing toward the impact surface, and is arranged so that the entrance pipe has an inner diameter x; and the impact surface is separated from the opening of the entrance pipe by a distance y, wherein y is between 3x and ⅓x. An exit pipe guide the exhaust gas stream out of the housing. A receptacle is removably connected to the hole in the bottom of the housing. The impact surface diverts the exhaust gas stream from a first flow direction to a second flow direction, causing the entrained particles to fall from the exhaust gas stream into the receptacle before entering the exit pipe.
