<p>The invention provides a rotary heat regenerator which includes a regenerator wheel (10) in which the regenerator matrix is formed of at least one strip (14) of synthetic organic plastic wound onto a central hub (12), with suitable spacing means being formed in the strip to form gas passages (18). The wheel (10) has reinforcing means provided by narrow portions extending radially in which the layers of the strip (14) have been adhered together, in addition to said a method is provided for providing reinforcement to the rotary heat recovery device formed of a spiral winding of at least one strip (14) of thermoplastic material, comprising applying to said strip (14) a heated member to form a radial fused portion.</p> |
