Natural draft cooling tower with shell disconnected from the substructure
Description
The aim of this paper is the analysis of results of a research done by Electricite de France, concerning a new type of cooling tower. The traditional structure (i.e. a hyperbolic shell supported by X shaped or diagonal columns) is replaced by two independent structures: the shell, becoming a self-contained structure, the lower rim being stiffened by an annular beam; the substructure, resting on the soil. This new type of cooling tower has an improved thermal performance due to the increase of the area of air entrance. Bearing pads are provided between the lower ring beam of the shell and the substructure. Any differential settlement can be coped with by jacking. The water distribution structure can be laid out so as to benefit from advantages offered by the presence of the stiff ring and columns of the substructure
Abstract (French)
La presente etude a pour objet d'analyser les resultats des recherches effectuees a l'EDF sur un refrigerant atmospherique de conception nouvelle. La structure traditionelle de ce type d'ouvrage constitue d'un voile et de poteaux diagonales ou en forme de X, est remplacee par deux structures independantes: le voile, rendu autostable par l'adjonction d'un anneau raidisseur; l'infrastructure reposant sur le sol. Le nouveau type de refrigerant presente l'avantage d'ameliorer le rendement thermique par augmentation des entrees d'air. Les tassements differentiels peuvent etre compenses par l'intermediaire d'appareils d'appui places entre l'anneau du voile et l'infrastructure. Enfin, le systeme de ruissellement peut etre amenage afin de beneficier des possibilites offertes par la presence de l'anneau et des poteaux rigides de l'infrastructureAdditional details
