1. A system for exhausting gases from one or more generators or engines, comprising:
a plurality of metal exhaust stack sections, slidably joined and in fluid communication, one to another, to form a continuous hollow column having an upper end with an opening and a lower end with an opening; a metal stand comprising a housing having a top, a bottom, an interior channel connecting an opening on the top to an opening on the bottom, the top opening configured to receive internally the lower end of the continuous hollow column and support the column in an upright vertical position, and three or more legs attached to the exterior of the housing that support the housing; a hanger bracket fixed to and extending below the bottom opening of the housing; and a metal connector tube having a first end adapted to collect exhaust gases from one or more exhaust pipes on the one or more generators or engines, and a second end releasably secured to the hanger bracket and forming a separation space between the second connector tube end and the bottom opening of the housing; wherein the system is configured so the exhaust gases from the one or more exhaust pipes flow into and through the connector tube and into and through the separation space and into the bottom opening of the housing in such a manner as to form a vacuum drawing ambient air into the separation space to mix with and cool the exhaust gases flowing through the channel and into and through the continuous hollow column for cooling and exhaustion from the upper end of the continuous hollow column; and each metal exhaust stack section has an outer surface that is grooved, serrated, ribbed, fluted/scalloped, or notched to increase the outer circumferential surface area of each exhaust stack section to displace heat. |
