Abstract
An arrangement is provided in an air preheater for mounting and adjusting the sector plates and the axial seal plates in relation to the rotor using one adjustable mounting means and a stabilizer assembly. The stabilizer assembly includes a stabilizer beam which is fixedly mounted to the external preheater structure, a pair of stabilizer lugs having one end fixedly mounted to the stabilizer beam, a pair of stabilizer arms each having a first end rotatably mounted to the other end of the stabilizer lugs by a torsion bar which extends between the stabilizer lugs, and a pinned linkage mechanism which rotatably mounts the second end of each stabilizer arm to the sector plate or axial plate.
Claims18
In a rotary regenerative air preheater including a rotor defining an axis, an external structure surrounding said rotor having a plurality of structure portions, and at least one plate mounted on one of said structure portions between said one structure portion and said rotor, means mounting said plate on said one structure portion comprising:
- a stabilizer beam fixedly mountable to said one structure portion, said stabilizer beam having oppositely disposed first and second ends;
- first and second stabilizer lugs having oppositely disposed first and second end portions, said first end portion of said first and second stabilizer lugs being mounted adjacent said first and second ends of said stabilizer beam, respectively;
- first and second stabilizer arms having oppositely disposed first and second end portions, said first end portion of said first and second stabilizer arms being rotatably mounted to said second end portion of said first and second stabilizer lugs, respectively;
- torsion bar means disposed intermediate said first and second stabilizer lugs and fixed thereto for transmitting force between said first and second stabilizer lugs;
- first and second mounting lugs having oppositely disposed first and second end portions, said first end portion of each mounting lug being fixedly mountable to said plate;
- and
- first and second linkage means for rotatably linking said second end portion of said first and second stabilizer arms in offset relationship to said second end portion of said first and second mounting lugs, respectively.
In a rotary regenerative air preheater including a rotor defining an axis, an external structure having a plurality of structure portions surrounding said rotor, and at least one plate mounted on one of said structure portions between said one structure portion and said rotor, mounting means for mounting said plate on said one structure portion, and adjustment means for adjusting the position of said plate relative to said one structure portion;
- said mounting means comprising:
- a stabilizer beam fixedly mountable to said one structure portion, said stabilizer beam having oppositely disposed first and second ends;
- first and second stabilizer lugs having oppositely disposed first and second end portions, said first end portion of said first and second stabilizer lugs being mounted adjacent said first and second ends of said stabilizer beam, respectively;
- first and second stabilizer arms having oppositely disposed first and second end portions, said first end portion of said first and second stabilizer arms being rotatably mounted to said second end portion of said first and second stabilizer lugs, respectively;
- torsion bar means disposed intermediate said first and second stabilizer lugs and fixed thereto for transmitting force between said first and second stabilizer lugs;
- first and second mounting lugs having oppositely disposed first and second end portions, said first end portion of each mounting lug being fixedly mountable to said plate;
- and
- first and second linkage means for rotatably linking said second end portion of said first and second stabilizer arms in offset relationship to said second end portion of said first and second mounting lugs, respectively;
- said adjustment means comprising:
- a mounting plate having oppositely disposed first and second end portions, said first end portion of said mounting plate being fixedly mounted to said plate;
- an adjustment rod comprising a first end portion linked to said mounting plate, a second end portion disposed exteriorly to said external structure, and a shaft portion extending from said first end portion to said second end portion of said adjustment rod;
- and
- third linkage means for rotatably linking said first end portion of said adjustment rod to said mounting plate.
