The heat regenerator 51 is detachable at one end from a burner B and at its other end from a reversing valve 58, and comprises two axially engaging portions 56 and 57, portion 56 comprising a cylindrical heat storage bed 59 and a surrounding annular layer 60 of ceramic fibre insulation, while portion 57 comprises a cylindrical body of refractory having a bore 61 forming a passage tapering towards valve 58. Heat storage bed 59 is a monolithic refractory block with multiple gas- carrying channels 65. Channels 65 convey combustion products from burner portion 52 to regenerator portion 56 when the bed is extracting heat from the products for storage. Alternatively channels 65 may convey air from portion 56 to portion 52 so that the air can be heated by the stored heat now released from the bed. <IMAGE> |
