A support structure for a rotary regenerative heat exchanger includes an upper section, a lower section, and a plurality of support members. The upper section includes an upper ring having a first exterior surface, an upper hub and at least three upper spokes each extending between and secured at respective ends thereof to the upper ring and the upper hub. Each of the plurality of support members are fixedly secured, directly or indirectly, to the upper ring and the lower section. An annular space is between the upper ring and the lower ring, which is configured to receive compartments of a rotor assembly. The upper hub, the upper spokes and the support members cooperate to provide rigidity to the support structure by cooperating to support and transmit the weight of the upper spokes, the upper ring and the upper hub to the lower section.

Low profile support structure for a rotary regenerative heat exchanger

A swing-arm sootblower for a rotary regenerative air preheater is mounted to sweep across the air preheater rotor at an adjustable constant speed or angular velocity. The sootblower has means for sootblowing with a relatively low pressure medium such as air or steam or with high pressure water. The nozzle unit is equipped with a low pressure nozzle and a plurality of high pressure nozzles. The high pressure nozzles are arranged in a row and the nozzle unit is mounted so that the row is at an angle to the swing arm such that the row of high pressure nozzles is parallel to the heat transfer plates and tangential to the rotor at the outside of the swing of the arm.
