Case Histories

Case History #1

A utility station in the southern U.S. whose forced draft fans were consuming excessive power and creating high levels of noise.

Case History #2

A utility station in the southern U.S. with structural cracking of a fan, associated ductwork and foundation.

Case History #3

A utility station in the southwestern U.S. experiencing cracking in the center plates of their forced draft fans.

Case History #4

An iron foundry in the southeastern U.S. with an induced draft fan that had frequent bearing failures and a reduced flow rate.

Case History #5

A pulp and paper mill in the southeastern U.S. having bearing failures and high vibration with their penthouse boiler seal air fan on their power boiler.

Case History #6

An aluminum plant in the eastern U.S. with inadequate ventilation from a potline work area.

Case History #7

A utility station in the southern U.S. experiencing excessive housing pulsations on two induced draft fans.

Case History #8

A pulp and paper mill in the southern U.S. needing additional secondary air flow to a recovery boiler to increase their liquor burning capacity.

Case History #9

A utility station in the western U.S. with an inadequate flow rate from two primary air fans that supplied five individual pulverizers.

Case History #10

A pulp and paper mill in the southern U.S. experiencing inadequate primary air flow on a recovery boiler.

Case History #11

A chemical plant in the eastern U.S. experiencing frequent bearing failures on a single inlet, overhung fan.

Case History #12

A utility station in the western U.S. with inadequate capacity from one of two identical forced draft fans.

Case History #13

A pulp and paper mill in the midwestern U.S. having poor control of a lime kiln attributable to the induced draft fan.

Case History #14

A utility station in the eastern U.S. with control difficulties on five primary air fans operated in parallel.

Case History #15

A cement plant in the northeastern U.S. with an inadequate flow rate from an induced draft fan.

Case History #16

A cement plant in the southeastern U.S. with an inadequate flow rate from two induced draft fans operated in parallel.

Case History #17

A pulp and paper mill experiencing cracking of a fan's ductwork and discharge stack.

Case History #18

A pulp and paper mill in the northeastern U.S. with high noise levels from an induced draft fan on a cogeneration boiler.

Case History #19

A pulp and paper mill in the southern U.S. with a lime kiln induced draft fan that was consuming excessive power and providing an inadequate flow rate.

Case History #20

A utility station in the northeastern U.S. which was unable to operate two gas recirculation fans simultaneously because of vibration problems.
