<p>A swing-arm sootblower (56) for a rotary regenerative air preheater is mounted to sweep across the air preheater rotor (14) at an adjustable constant speed or angular velocity. The sootblower (56) has means for sootblowing with a relatively low pressure medium such as air or steam or with high pressure water. The nozzle unit (78) is equipped with a low pressure nozzle (108) and a plurality of high pressure nozzles (110). The high pressure nozzles (110) are arranged in a row and the nozzle unit (78) is mounted so that the row is at an angle to the swing arm (74, 76, 77) such that the row of high pressure nozzles (110) is parallel to the heat transfer plates and tangential to the rotor (14) at the outside of the swing of the arm (74, 76, 77).</p> |
