Abstract: An improved design associated with the fabrication and construction of a chimney stack wherein the liner material utilized as the inner liner of the stack which comes into direct contact with the flue gases being conveyed by the chimney stack to the outside atmosphere comprises erodable material having embedded therein a resistance type electrical or thermal conductivity type alarm system capable of detecting the degree of erosion of the erodable liner of the chimney stack thereby providing the ability to monitor when reconditioning of the inner liner of a chimney stack is required. Additionally, there is also incorporated the utilization of turbine blades positioned within the stream of gas flow within the chimney stack such that the flue gases cause the turbine blades to rotate, said rotation then being converted into the generation of electrical energy for utilization outside of or in accordance with the operation of the chimney stack.

Abstract: This invention relates to an improved design associated with the fabrication and construction of a chimney stack or other structures of extreme height such as towers, masts, and the like, wherein precast sections are utilized having reinforcing steel members positioned therein so as to permit upon stacking of said precast sections, vertical alignment thereof such that said reinforcing steel members are positioned in vertical alignment throughout the height of the chimney so as to achieve optimum structural integrity. Additionally, the invention herein utilizes the reinforcing steel members to facilitate the movement of said precast sections of said chimney by use of threaded eye bolts which are easily detachable from the steel reinforcing members once the precast sections of said chimney have been lifted and aligned in place.

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.
