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. Furthermore, by selectively controlling the rotation of the turbine blades and their position within the stream of gas flow within the chimney stack, there is achieved the ability to selectively generate turbulence down stream from the turbine blades' location thereby providing for the ability to selectively reduce the build up of corrosive particles on the erodable liner of the chimney stack thereby increasing the usable life of the inner liner.
