1. A spider diffuser system for use in a thermal energy storage tank, said tank comprising an outer wall having a generally cylindrical inner surface surrounding a hollow internal space in the tank, said spider diffuser system comprising:
a centrally disposed manifold structure, said spider diffuser system being arranged for mounting in said space with the manifold structure in vertically spaced relationship relative to a thermocline formed in a temperature stratifiable liquid in said space during operation of the tank, said manifold structure having an internal chamber, said manifold structure including an opening for introduction of a said liquid into the chamber or discharge of a said liquid from the chamber; and a diffuser pipe assembly comprising a plurality of elongated diffuser legs mounted in the space, each leg being attached to said manifold structure so as to extend generally outwardly from said structure and toward said inner surface, said legs each having an internal channel in fluid communication with the chamber and a plurality of apertures distributed along the length of the leg, said apertures intercommunicating said channel with the space. |
