ABSTRACT:
This invention relates to an improved design associated with the fabrication and construction of a double shell chimney stack capable of conveying hot gases generated in conjunction with industrial endeavors to a height within the atmosphere sufficient to meet current pollution standards. In accordance with the invention, an inner core member thermally insulated is contained within, as well as supported by, an upright outer structural column member, there being selectively positioned on the exterior wall of said inner core member, between said inner core member and said outer structural member, vibrator mechanisms capable of being selectively actuated so as to vibrate said inner core member when desired. In this manner, the double shell chimney is in effect self cleaning without requiring the shutting down of the stack to achieve same since by mechanically vibrating the inner core member of said double shell chimney during its normal operations, particulate matter is prevented from building up on said inner surface of said inner core member as well as being dislodged from the inner surface of said inner core member and is either allowed to fall to the bottom of said chimney stack whereupon it is removed in a manner well known in the prior art or said particulate matter passes out of the top of the chimney stack with the rising gasses passing through said chimney stack. Additionally, there is also incorporated in the overall design of said chimney stack means as part of the inner core member of said chimney stack for maintaining the flue gas temperature above the acid dewpoint temperature of the various acid vapors contained in said flue gases passing through said stack as well as additionally incorporating in the overall design of said chimney stack means for creating a pressure differential between the air space existing between the inner core member of said chimney stack and the outer structural column member and the center passageway of said chimney stack thereby reducing to a minimum maintenance requirements associated with said chimney stack as well as extending their operating life. By incorporation of the above in an overall design for a chimney stack, the advantages and achievements of the present invention are realized.
