Claims

[Scope of utility model registration request]

A rotary regenerative heat exchanger that injects a soot blower such as superheated steam onto a rotor-type heat storage body, which is constructed by alternately laminating undulated plates and flat plates as heat storage plates, to soot-blow away deposits on the surface of the heat storage plate. A protection plate of a predetermined width is disposed along the edge of the soot blower injection nozzle side of the radial diaphragm that divides the rotor-type heat storage body in the circumferential direction or the basket that holds the heat storage plate, A rotary regenerative heat exchanger characterized in that the soot blower is prevented from being sprayed onto the end of the heat storage plate located near the diaphragm or the basket.
