BURNER FOR USE IN HEATING AN ENCLOSURE

摘要

Figure 2 The present invention relates to a heat regenerator for use in heating an enclosure such as a furnace. The heat regenerator 51 is detachable at one end from a burner B and at its other end from a reversing valve 58. The regenerator 51 comprises two axially engaging portions 56 and 57, the front portion 56 comprising a cylindrical heat storage bed 59 and a surrounding annular layer 60 of a ceramic fibre insulation material. The rear portion 57 comprises a cylindrical body of refractory material having a bore 61 forming a bottle-neck type passage tapering towards the valve 58. The heat storage bed 59 comprises a monolithic refractory block through which a multiplicity of axially aligned gas-carrying channels 65 extends. These channels 65 convey combustion products from the burner portion 52 to the regenerator portion 56 in one mode of operation where the bed is extracting heat from the products for storage. In another mode of operation the channels 65 convey air from the portion 56 to the portion 52 so that the air can be heated by the stored heat now released from the bed.
